− TM Samsung One NAND and managed NAND including eMMC up to rev 4.4 (in muxed I/O mode) The i.MX53 system is built around the following system on chip interfaces: • 64‐bit AMBA AXI v1.0 bus – used by ARM platform, multimedia accelerators (such as VPU, IPU, GPU3D, GPU2D) and the external memory controller (EXTMC) operating at 200 MHz. • 32‐bit AMBA AHB 2.0 bus – used by the rest of the bus master peripherals operating at 133 MHz. • 32‐bit IP bus – peripheral bus used for control (and slow data traffic) of the most system peripheral devices operating at 66 MHz. The i.MX53 makes use of dedicated hardware accelerators to achieve state‐of‐the‐art multimedia performance. The use of hardware accelerators provides both high performance and low power consumption while freeing up the CPU core for other tasks.

3.6. SATA 7‐pin Data Connector (J7) The SATA connector provides the means to connect an external SATA memory device to the Quick Start board. Commonly, this would be an External hard drive or a DVD/CD reader. Power for the SATA device needs to be supplied externally by the user via a 12‐pin power connector. It is possible to boot from a SATA drive by making OTP fuse changes. Once the fuse changes are made, they cannot be reversed. 3.7. VGA Video Output (J8) A standard VGA signal is output directly from the i.MX53 Processor with minimum external components required. Power for the TVE module of the i.MX535 Processor is supplied by VLDO7 of the PMIC and is set to 2.75V. If VGA output is not desired, it is possible to program the PMIC to turn off VLDO7 to conserve power. The VGA output supports a variety of video formats up to 150 Mega‐Pixels per second. Level shifters are required on the Horizontal and Vertical Synchronization signals as well as the VGA I2C communications signals in order to meet VGA specifications. Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...
3.10. Dual USB Host Connector (J2A) The USB module of the i.MX53 Processor provides two high speed USB PHYs that are connected to each of the USB‐A Host Jacks on connector J2. One PHY provides Host‐only functionality and is connected to the upper USB jack on the connector tower. The second PHY is USB 2.0 OTG capable and is connected to the lower USB jack on the connector tower. Both jacks receive 5V power directly from the 5V Wall Power Supply, via a FET that can be controlled by software, and a 1.1A Poly‐fuse. The PMIC provides an over‐voltage functionality to limit voltage applied to the USB jack in the event that a DC Power Supply other than the original supply provided is used. Also, there is no current regulating device to limit current supplied to each jack, other than the Poly‐fuse. NOTE The lower USB Host Jack is cross connected with the Micro‐B USB Device connector. This was done as a convenience to the user as cables with micro‐A plugs are still uncommon at the time the board was designed. The USB OTG PHY will switch to ‘device’ mode if a USB Host is attached to the micro‐B connector with a cable. This design is not recommended for release to the general electronics consumer population. This board has not been tested for USB compliance.

Microphone Jack. A 2.5mm to 3.5mm adapter may be necessary to convert the microphone, mono headphone device to fit the Microphone Jack. On both the Headphone Jack and Microphone jack, a fourth pin is used to detect the insertion of a plug into either jack. When a standard 3‐pin device is inserted into the 4‐pin jack, the detect line is grounded, indicating to the i.MX53 Processor that the plug has been inserted. 3.13. 5V Power Connector (J1) A 2.0mm x 6.5mm barrel connector is used which should fit standard DC Plugs with an inner dimension of 2.1mm and an outer dimension of 5.5mm. If an alternate power supply is used (not the original, supplied power supply), it should supply no more than 5.25V / 3A output. If the PMIC senses too high voltage at the connector input, it will turn off isolation FET Q1 to protect the Quick Start board. In between the Power Connector and the isolation FET is a single blow, fast acting fuse to protect the Quick Start board from an over current situation fault. If a Wall Power Supply is properly connected to the Quick Start board, and the green 5V power LED indicator is not lit, it could mean that either the fuse has been blown, or that the voltage output of the power supply is too high.

3.15. JTAG Connector (J15) A standard 20‐pin ARM JTAG connector is provided on the Quick Start board. Logic signals to the JTAG connector are 1.8V signals. A 1.8V reference signal is provided to pin 1 of the connector so that the attached JTAG tool can automatically configure the logic signals for the right voltage. If the JTAG tool does not have an automatic logic voltage sense, make sure that the tool is configured for 1.8V logic. JTAG tools that have been specifically tested with the Quick Start board are: • JTAG Commander (Macraigor) • DS‐5 and RealView (ARM Ltd.) • Trace32 (Lauterbach) • J‐Link (Segger/Codesourcery) • J‐Link (IAR) Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...
User Interface Buttons There are four user interface buttons on the Quick Start board. Their functionality is as follows: POWER: In the ‘Power Off’ state, momentarily pressing the POWER button will begin the PMIC power on cycle. The PMIC supplied voltage rails will come up in the proper sequence to power the i.MX53 Processor. When the processor is fully powered, the boot cycle will be initiated. In the ‘Power On’ state, momentarily pressing the POWER button will send a signal to a GPIO port for user defined action, but will not initiate a hardware shutdown. In the ‘Power On’ state, holding the power button down for greater than 5 seconds will result in the PMIC initiating a shutdown to the ‘Standby’ power condition. This will also be the result from the ‘Power Off’ state as the PMIC will transition into the ‘Power On’ state and will still see the POWER button as held down. Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...
The User status LED (D16) is a Green LED gated by the PATA_DATA1 (L3) GPIO pin. The developer is left to determine the action of this pin in code. Sample codes do not assign functionality to the pin. The LED comes on by default when the processor starts up. FLT: The FLT status LED (D14) is a Red LED gated by the NVDD_FAULT signal from the PMIC. The LED will turn on anytime the PMIC is not outputting the requested voltages or when the PMIC senses a fault condition and will begin to power down the voltage rails. This may aid in trouble shooting power problems if both the PMIC and FLT LEDs are on at the same time, it indicates that the PMIC is causing a shutdown based on a fault it has sensed. 3.3V: The 3.3V status LED (D10) is a Blue LED gated by the External Regulator 3.2V power rail. This power rail can be turned off by software for power savings measures. This LED provides an easy visual recognition as to the status of this bus.

The battery charging feature is an autonomous operation of the Dialog DA9053 PMIC that does not require software support. Battery charging may be prevented by software by making registry changes to the PMIC. The developer may need to verify in software that PMIC registry settings are proper for battery charging operations. The footprints for testing with a battery were included for skilled developers looking to experiment. 3.20. Optional Back‐Up Coin Cell posts (JP1, JP2) On the Quick Start board, there are two through‐holes (JP1 and JP2) next to the power connector. These through‐holes are positioned to hold a Lithium coin cell battery (Sanyo ML1220‐VM1 or equivalent). For proper operation, the coin cell posts should be soldered direction to the Quick Start board, with the positive terminal connected to JP1 and the negative terminal connected to JP2. The DA9053 PMIC will charge the coin cell when 5V Wall Power is available. When 5V Wall Power is removed, the coin cell will provide power only to the RTC power rail (VLDO1) supplying power to the i.MX53 processor. The length of time a coin cell can power the RTC subsystem may vary.

1) Isolate power to major subsystems or components. 2) Install small value precision resistors to measure current consumption of major subsystems. 3) Or reconfigure power sources to subsystems or components using wires soldered to the pads. To restore a shorting trace back to normal after the trace is cut, it is only necessary to solder a Zero Ohm resistor to the pads. 4. Quick Start Board Connectors and Expansion Port The Quick Start board provides a number of connectors for a variety of inputs and outputs to and from the board. The following subsections describe these connections in detail.

(J1) on the board as show in Figure 1. If the original power supply is lost, it is possible to use a substitute power supply for the Quick Start board. Voltage above 5.5V, and below 12V, will trigger the Over‐ Voltage protection circuitry on the board. It is not recommended to use a higher voltage since, in the event of a failure to the protection circuitry, damage to the board will result. A voltage supply above 12V will damage the PMIC part.

4.8. micro‐B USB Device Connector (J3) The Quick Start board has one micro‐B USB device connector that can be used to connect the Quick Start board to a USB Host computer. The micro‐B connector is connected to the High‐speed (HS) USB 2.0 OTG module of the i.MX53 processor and is cross connected with the lower USB Host port on J2. When a 5V supply is seen on the micro‐B connector (from the USB Host), the i.MX53 processor will configure the OTG module for device mode, which will prevent the lower USB Host port from operating correctly. The 5V power provided by the attached USB Host is only used by the i.MX53 processor for sensing that the host is present. The Quick Start board will not draw power from the connected USB Host and will not operate without a 5V DC power source or charged Li‐ION battery. The micro‐B connector is keyed and will not accept a micro‐A plug from a cable. A micro‐B to USB‐A cable is supplied as part of the Quick Start kit and can be inserted into the micro‐B USB connector at the point shown in Figure 8. micro‐B USB Connector (J3) Figure 8. micro‐B USB Device Connector (J3) Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...
It is possible to initiate a boot from an attached SATA device. See the software reference manuals for instructions on how to configure the Quick Start board for SATA boot. The SATA Data cable is plugged into the Quick Start board at the location shown in Figure 9. SATA 7‐pin Data Connector (J7) Figure 9.

4.10. SD Card Connector (J5) The Quick Start board has one full size SD/MMC connector that can be used for memory, or for third‐ party SDIO type cards such as WiFi or Bluetooth. The SD Card Connector (J5) connects a full 8‐bit parallel data bus to the SD3 port of the i.MX53 processor. The SD Card Connector receives power from the DCDC_3V2 power rail supplied by the supplementary Voltage Regulator. The Quick Start board does not come pre‐configured to boot from the full size SD Card Connector, but the board can be modified to support booting from this connector instead of the microSD Card Connector. See the section on Quick Start boot options on how to make the necessary changes (Section 5.4.2). The SD Card Connector is not spring loaded, so pushing the card into the slot will not initiate an action to disengage the SD Card. The SD Card is inserted facing up at the location shown in Figure 10. SD Card Connector (J5) Figure 10. SD Card Connector (J5) Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...
4.11. microSD Card Connector (J4) The Quick Start board has one micro SD/MMC connector that can be used for memory. The micro SD Card Connector (J4) connects a 4‐bit parallel data bus to the SD1 port of the i.MX53 processor. The micro SD Card Connector receives power from the VLDO3 power rail. The Quick Start board comes configured to boot from the micro SD Card Connector by default. The micro SD Card Connector is spring loaded and will eject a properly inserted card if the card is pushed in again. Caution: If the card is ejected while serving as the file system, the processor will undergo a software crash. The micro SD Card is inserted facing up at the location shown in Figure 11. microSD Connector (J4) Figure 11. microSD Card Connector (J4) Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...
4.12. 20‐pin ARM JTAG Connector (J15) The Quick Start board contains a standard 20‐pin ARM JTAG connector (J15) for advanced debugging with a third‐party emulator. The header is configured for use with 1.8V data signals. The developer should exercise caution when selecting the appropriate debugging tools. If an emulator set for 3.3V power and data is connected to the Quick Start board, the i.MX53 processor will be damaged. The emulator JTAG cable is connected to the bottom side of the Quick Start board at the location shown in Figure 12. VGA DB15 Connector (J8) JTAG Connector (J15) Figure 12. JTAG Connector (J15) Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...
The Quick Start board includes a 30‐pin (Hirose, DF19G‐30P‐1H(56)) connector for use with an LVDS display. The developer can create custom cables that will allow the Quick Start board to be used with a wide variety of commercially available LVDS displays. The pin‐out for this connector is used on other Freescale designed boards in the i.MX53 series, such as the MCIMX53SMD tablet. Freescale has available a cable and LVDS display (HannStar, HSD100PXN1‐A00‐C11) for purchase if the developer wishes to use a pre‐tested configuration. The LVDS display can be used in conjunction with the optional LCD display, the VGA output or the optional HDMI card, as long as the total video output does not exceed the specified limits of the i.MX53 processor. The pin‐out table for the connector is located in different section of this user guide. This connector is located on the bottom side of the board in the location shown in Figure 13.

The power sequence requirements for the i.MX53 Applications Processor from the data sheet are as follows: NVCC_SRTC_POW (VLDO1) VCC, VDDA, VDDGP, VDD_REG [in any order] All other supplies [in any order] NOTE: in case the internal regulator is used for VDDA generation, the VDD_REG should be powered up together with VCC and VDDGP, before the other supplies. In case the internal regulator is not used to generate VDDA (as on the Quick Start board), the VDD_REG is independent and has no power‐up restrictions. The power on timing sequence shown in Table 1 is the sequence programmed into the Dialog PMIC. It is one way of providing sequences power to the i.MX53 processor. Designers are free to change the power timing sequence on their own board designs as long as the timing requirements are met. Freescale has not formally tested other power on timing sequences. Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...
Table 1. Regulator Timing Sequence The Dialog PMIC will enter a SHUTDOWN/STANDBY condition by one of three ways; By a command from the i.MX53 Processor via I2C communications, by i.MX53 Processor action to hold the nONKEY/KEEPACT pin low for at least five seconds, or by hardware if the user holds down the POWER button for more than five seconds. All three actions result in the Dialog PMIC powering down the voltage regulators in reverse order of the power on sequence, except for VLDO1. A subsequent press of the POWER button will initiate the same power on sequence as shown in Table 1. The various power rails supplied by the PMIC are discussed in the section on Quick Start Power Rails. Other features of the Dialog PMIC implemented by the Quick Start board are discussed in subsequent sub‐sections including: Li‐ION Battery Charging, Backlight LED Driver, Touch‐Screen Operation, Miscellaneous.

In designing a board using the Dialog PMIC, it is important to include a capacitor of 47 uF or greater attached to the VBAT pin if any operations are planned without a Li‐ION battery. If during the initial pre‐ charge phase, the Dialog PMIC does not sense any voltage present when the pre‐charge voltage is momentarily removed and VBAT voltage is measured, the PMIC will assume a massive board failure and will not supply any voltage via the regulators. 5.2.3. Backlight LED Driver The Dialog PMIC provides a Boost circuit which controls an external MOSFET Q8. The PMIC is capable of driving 3 independent strings of up to 5 white LEDs each with a voltage of approximately 24 Volts and a maximum of 50 mA. The Quick Start board does not have a direct connection for white backlight LEDs, but does supply one connection to the Expansion Port that can be used to support an attached LCD Daughter Card. The Expansion Port uses the LED1_IN port of the PMIC. Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...

5.2.5. Miscellaneous If a coin cell battery is attached to the Quick Start board, it will automatically charge using the programmed charging settings whenever wall power is supplied to the Quick Start board. When the battery voltage reaches the programmed level, charging will stop. Battery discharge will not begin until wall power is removed from the board and, if a Li‐ION battery is attached, the main battery discharges to the battery cut off level. There are two port ID traces connected from the Expansion Port header to two of the ADC pins of the PMIC. Each unique Daughter Card designed by Freescale has a different resistor value attached to the two ID traces on the Daughter Card. It is possible to use this voltage divider identification system to determine at boot time if a daughter card is attached, and if so, which specific daughter card it is. Resistor values for the two daughter cards commonly used with the Quick start board are shown in Table 3. Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...
The PMIC has several different options for Pull‐Up levels on each of its output pins. In some cases, VDDOUT is one option, along with power supplied to both the VDD_IO1 (L4) and VDD_IO2 (K4) pins as Pull‐Up source. The exact source of Pull‐Up power is determined by the registry settings of the PMIC and can be pre‐programmed at the factory as the designer wishes. Some Pull‐Up registry settings apply to groups of pins, so care must be made in selecting which source power source is used for a particular grouping of pins. The Dialog PMIC Datasheet contains much more detailed information on the registry settings. For the Quick Start board, VLDO3 (3.3V) is connected to VDD_IO1 primarily to ensure that the 3V3_EN signal sent to the external regulator is sufficient to turn on the regulator, and VLDO8 (1.8V) is connected to VDD_IO2 to provide for proper I2C TTL logic levels.

Expansion Port (HDMI) 30 mA SD Card 60 mA For the Expansion Port and the SD Card socket, it may be that the current draws exceed the above estimates if a custom designed board is added to the Expansion Port, or if an SDIO device is plugged into the SD Card Socket (ie, WiFi, Bluetooth). The external voltage regulator is capable of supplying up to 1A of current and should be capable of accommodating most custom configurations. Since the Quick Start board was originally designed, it has been found that VDDA, VDDAL, and DIG_PLL can all be powered internally by the i.MX53 processor (with the correct eFuse settings). This would then free the PMIC VLDO2, VLDO6 and VLDO10 power sources for other uses. VLDO6 and VLDO10 will be able to supply the above expected loads, provided a high current draw SDIO card is not inserted in the SD Card Socket. The designer is free to rearrange power rails as desired. Freescale Semiconductor Hardware User Guide for i.MX53 Quick Start Board, Preliminary Rev 0.91 PUBI – Public Use Business Information...

5.4.1. Peripheral Module Logic Voltage Levels By convention, pins used on the I.MX53 Processor to set module logic voltage levels begin with NVCC_. This is to aid the developer in the design of a project based on the i.MX53 Processor. There are 25 such pins used, and practically speaking, they supply the internal pull‐up voltages for pins designated for data output. These 25 pins are shown in detail in Table 4. Module Voltage Supplies. Once a voltage level is selected for a particular module, all pins within that module will use the same voltage level. It is important for the developer not to try to use an external pull‐up to a different voltage level for individual pins. Level shifters must be used if certain pins need to have different voltage levels to interface with external ICs. If a different voltage level is used on an external pull‐up, one or both of the affected power rails will most likely have a different voltage level than intended throughout the design. On a newly designed board that shows unexpected voltage levels, this may be the first thing to check. On the Quick Start board, there are a number of unpopulated pull‐up resistors. This is a result of the initial design being conservative, and the addition of external pull‐up resistors to supplement internal i.MX53 pull‐up supply voltage. Subsequent Quick Start board usage has shown these pull‐ups to be unnecessary, so they are unpopulated.

Figure 18. Clock Source Locations The clock source for the Ethernet PHY is a 50 MHz Oscillator (X1) with an enable pin and is shown in Figure 18. The oscillator was originally placed to support both the SATA module and the Ethernet PHY. It is no longer used for the SATA module, and only supplies a clock signal to the Ethernet PHY. It is powered by the DCDC_3V2 power rail and, by default, is always on when the DCDC_3V2 rail is powered on. It is possible for the developer to remove resistor R110 and place a zero Ohm resistor across R197 to give the developer software control of the oscillator through pin GPIO_4 (D4).

5.4.5. Watch Dog Timer The i.MX53 Application Processor has an internal Watch Dog Timer circuit. On the Quick Start board, the WDOG output is assigned to GPIO_9. The WDOG is an active low signal. The Dialog PMIC does not have a specific pin to accept a Watch Dog signal to force a Processor reset. Therefore, the WDOG signal is modified by hardware components on the Quick Start board and applied to the Processor Reset pin (POR_B, pin C19). By using an active‐low enabled buffer, the active low WDOG signal can be transformed into a low pulse, which returns back to the logic high state immediately after the i.MX53 Processor resets ( ~ 700 nsec). This allows the processor to reset the WDOG signal and then come out of reset. The buffer IC also is in a tri‐state condition when the WDOG signal is normally high, thus allowing the push‐button reset circuitry to work. The Watch Dog circuitry is shown in Figure 19.

5.4.6. Wakeup After User Initiated Standby Q13 is a dual P‐channel/N‐channel MOSFET designed to take a transition from a low state to a high state on PMIC_ON_REQ (pin W15) and turn it into a PMIC nONKEY request to bring the Dialog DA9053 chip out of a standby state to a fully on state. The PMIC_ON_REQ pin has been designed to work with the Freescale companion PMIC chip and is always in a high state even if the user forces the board into standby with the nONKEY. To configure the wakeup after user initiated standby feature, the user first has to program the software to transition the PMIC_ON_REQ to the low state after a start up or resume after standby operation. This will place the circuit in a correct configuration to request a startup from the standby state. Without this software change, pressing the nONKEY after a forced standby will not wake the board back up out of sleep. To keep the board operating correctly before this software modification is made, Q13 has not been populated on the board. When the developer has modified code to make this work, Q13 can be populated to complete the circuit. Information on Q13 can be found in section 14, Bill of Materials.

The DDR_VREF is created by a simple voltage divider using 470 Ohm 1% resistors and 0.1 uF capacitors for stability. The relatively small value resistors provide enough current to maintain a steady mid‐point voltage. The calibration resistors used by the four DDR3 chips and the Processor are 240 Ohm 1% resistors. This resistor value is specified by the DDR3 Specifications. There is a 200 Ohm resistor between each clock differential pair to maintain the correct impedance between the two traces. The DDR3 SDRAM should be rated for 1066 MHz or faster. For skilled designers wishing to double the amount of DDR3 SDRAM available for use with the i.MX53 processor using eight x8 width DDR3 chips, the following considerations should be weighed carefully before proceeding: Four DDR3 chips on a chip select line will exceed the current supply capability of the VBUCKMEM power source. An additional 1.5V power source would need to be added. Also, attaching the address lines to eight DDR3 chips is a great amount of loading. Premium PCB materials would be required to reduce losses. Freescale has tested and validated using eight DDR2 SDRAM chips in this manner. Using eight DDR3 SDRAM chips has not yet been tried.

The SD1 Clock trace has a 22 Ohm series termination resistor (R211). This resistor is inserted to prevent a reflected signal from being sensed by the i.M53 processor. This has been found to occur on MMC card operation and is recommended for all designs. In addition, the following eSDHC channel 1 trace is pulled high to 3.3V (VLDO2_3V3). SD3 Command (R76) By default, the Quick Start board is manufactured with a 3M 29‐08‐05WB‐MG part for availability reasons. The combined Data3/Card Detect trace is not supported by the BSP software. It is possible for the developer to remove the original card socket and repopulate the position with an alternate microSD Card Socket made by Proconn, MSPN09‐A0‐2000. The developer should also then populate R108 with a suitable pull‐up resistor (10K). This will then give the developer the option to use the card detect trace for channel 1 connected to EIM_DA13 (pin AC7).

Main power to the SD Card Connector is from the external LDO regulator (DCDC_3V2). If this regulator is turned off for power savings purposes, the card socket will not function. It is possible for the developer to cut the trace between the pads of SH32 and attach a different source of power to the pad next to the card socket via a wire solder. Note that the eSDHC module internal to the i.MX53 processor is operating at 3.3V, therefore it is recommended that the alternate source also be 3.3V. Cutting the SH32 trace should only be used if a SDIO device inserted into the socket is drawing more power than the LDO Regulator is capable of supplying. The SD3 Clock trace has a 22 Ohm series termination resistor (R212). This resistor is inserted to prevent a reflected signal from being sensed by the i.M53 processor.

The Component Video signals are terminated to ground, each with a 75 Ohm resistor to meet cabling requirements. A separate VGA ground plane has been created to minimize noise on the video signals by necking through a small trace. The voltage reference signal for the TVDAC module is provided by placing a 1.05K 1% Ohm resistor at pin Y18. The constant current source provided by the TVDAC module generates the exact voltage reference required by the VGA standard. A 0.1uF capacitor should be connected to pin AA19 to reduce noise on the voltage reference sense point. Each of the Component Video output traces should be connected to their respective feedback pins. This provides the Cable Detection (CD) circuitry the ability to detect whether a cable has been plugged into the connector. The CD circuitry is not active for TV signal output, so it would not be necessary to connect the feedback circuit in that case. If any signal filtering or conditioning components are added to the Component Video traces, the feedback pins should be connected after the additional components (ie, feedback pins should tap into to the connector side of the Component Video signals). A ferrite bead is recommended near the voltage input pins of the TVDAC module to reduce noise in the video module.

Display Control 3.3V (VLDO3_3V3) I2C channel two 3.2V (DCDC_3V2) I2C channel three 3.3V (VLDO3_3V3) Isolation resistors on the i2C channel two traces (R213, R214) provide a means of isolating the LVDS connector from other functions on the board if the LVDS connector is interfering with I2C communication. In addition, the empty pads can also serve as attachment points for hand soldered wires if the developer wishes to run different signals to this connector. The i.MX53 Applications Processor has both an internal and external method to measure Band Gap resistance. If the internal method is chosen by software, pin AA14 can be left floating. If the external method is desired, a 28.0K 1% Ohm resistor should be attached between pin AA14 and ground. It is recommended that this resistor be added routinely to give software the option of choosing between the two methods. It is also recommended to place a 49.9 1% Ohm resistor as the voltage input pin of U14 (NVCC_LVDS_BG) to filter the power used in measuring the Band Gap.

The developer is free to reprogram the voltage of the LDO regulator on the PMIC for whatever voltage may be required subject to the following limitations (1.25V – 3.6V, 100mA). The proper connector to mate with Expansion Port J13 is made by Samtec, QTH‐060‐XX‐L‐D‐A, where XX determines the height of the connector.

The Quick Start board is also designed with a cable detect feature on both the Headphone and Microphone Jacks. One option would be to use an audio connector with an internal flag that would make or break depending on whether the connector barrel was inserted into the jack. These connectors are available, but are often more expensive and may have supply problems. On the Quick Start board, a four pin, Audio/Video style connector was chosen to implement the cable detect feature. When a three connector cable is inserted into the connector, the cable detect pin is shorted to the ground pin, sending an active low signal back to the processor to indicate that a cable was inserted. For this reason, the ground pin on the Microphone and Headphone Jacks must be system ground and not a virtual audio ground. Therefore, the Audio CODEC was designed to use the AC Coupled audio mode which makes use of two 220uF capacitors. If the developer wishes to design a board that uses a flagged jack for cable detection or does not implement a cable detection scheme, it would then be possible to use the Direct Drive feature of the Audio CODEC and eliminate the need for the large capacitors. The Audio CODEC can be reset by software via the I2C channel, but there is no hardware reset pin on the CODEC. Should I2C communications be lost between the Audio CODEC and the Processor, it may be necessary to shutdown DCDC_3V2 power to the Quick Start board and reinitialize the Audio CODEC by the power on sequence.

Receive inputs to correctly match the device attached. This eliminates the need for cross‐over cables when directly connecting to another Ethernet end device. The LED status indicators are driven by the PHY to show a connected link and activity on the link. It is important to note that the LED control lines from the PHY also serve as PHY feature selection options. At boot time, the LED1 control pin serves to determine whether the 1.2V internal regulator should be turned on or off, and the LED2 control pins determines whether the PHY accepts an external reference clock or internally generates the clock signal and outputs it to the processor for reference. See the LAN8720 datasheet for further details. If a board designer wishes to reduce costs in the implementation of Ethernet, it is possible to replace the oscillator with a lower cost 50 MHz crystal. The LAN8720 has more information on this implementation. The oscillator was originally designed to support two different subsystems on the board, and is no longer an necessary expense.

USB Device port. In the normal implementation of OTG, the same connector is used for both Host and Device USB connections. A high or low signal on the USB ID pin would indicate whether a Host (A) plug or a Device (B) plug was attached. Since most Host plugs available today are the full size plugs, but most portable USB Devices are moving toward the Micro‐B connector, a two connector approach was implemented on the Quick Start board. The USB_5V power supplied by an attached Host device through the Micro‐B connector will provide a TTL logic high signal to the OTG Port through USB_OTG_ID (pin C16). The ID signal is corrected to the proper logic by way of a simple voltage divider. When the OTG Port senses this logic high condition, the OTG Port will switch to device operations, regardless of whether there is a USB Device plugged into the Lower USB Host Port. This USB OTG configuration is used for demonstration purposes only and is not recommended for mass production. The developer is cautioned to only plug one cable into the Lower USB Host Port OR the micro‐B Device port at a time, since two cables might degrade the USB signal beyond acceptable operating limits. The External USB 5V power supplied by a connected USB device is only used in two locations on the Quick Start board. It is used to provide the USB ID signal (passive sense) and to provide the USB_OTG_VBUS reference signal. For the board designer, two 6.04K Ohm 1% resistors are used, one attached to each of the Host1 and OTG Ports. These resistors are used to set the Band Gap levels.

The JTAG_MOD pin used by the JTAG module of the i.MX53 Processor determines how much of the i.MX53 processor is connected to the JTAG Debugging device. In the pull‐down mode (default on the Quick Start board) allows all of the i.MX53 TAPs (SJC, SDMA, ARM) to be connected to the debugging device in a daisy chain connection. If the JTAG_MOD pin is pulled high, then the attached debugging device can only access the SJC TAP. Three other common JTAG signals used by debugging devices (Return Clock, Data Enable, and Data Acknowledge) are not used by the i.MX53 Applications Processor and are either pulled‐up or pulled‐ down by the Quick Start board. On the Quick Start board, the logic signals for JTAG are designed to be 1.8V. A 1.8V reference signal from VLDO8_1V8 is connected to pin 1 of the 20‐pin JTAG connector to provide this logic level signal to the attached debugging device. In addition, for debugging devices that required power, a limited amount (~0.5 A) of 3.2V power can be supplied to the debugging device. If the device requires 1.8V power (instead of 3.2V power), the Quick Start board can be configured to supply this as well, but in a very limited amount (100 mA).

2) UART Test. When the test is running, the test expects different characters to be input from the keyboard of the host computer. After a character is input, the i.MX53 Processor receives the input, transmits to the terminal window the received character, and then asks the user to confirm that the character is correct by pressing the ‘x’ key. The test is exited by typing an ‘x’ as an input character. 3) DDR Test. The test writes predetermined data onto the DDR3 memory, reads those memory blocks back out, and then compares the two values for errors. If the values match, the test passes. 4) USBH1 Enumeration Test. Any USB device is plugged into the upper HOST connector (the lower port is connected to the USBOTG module). After confirming that a USB device is plugged in, the I.MX53 will read the device enumeration data and print it out on the terminal window. If the Processor cannot read enumeration information, the test fails.
