Page 19 SIM to a PC or powered USB hub. The complete module may require as much as 500mA from the USB power supply, so ensure that the USB hub or USB power supply can deliver enough power. The SIM225 can support concurrent connection from some of these supplies. See the Power Supplies for details.
Page 20: Module Feature Detail
SIM225 Technical Reference Manual MODULE FEATURE DETAIL RENESAS RX63N/RX631 MCU At the heart of the SIM225 is a 100MHz 32-bit Renesas RX63N/RX631 MCU equipped with extensive analog and digital peripherals. Features include: MCU Core & Memory 100MHz 32-bit core ...
Page 21: Mcu Boot Modes, Switch S4, And The Usb Boot Flash
Note that on the SIM225, the MCU should normally be operated at 96MHz to ensure the clocking system can generate the appropriate clocks for SRAM, USB, and other peripherals. The following table summarizes the size, speed, and configuration of each family member:...
Page 22 Boot Mode selected, the Renesas firmware reads P35 (NMI#) and finds it pulled high, causing the USB device port to tell a connected USB host (such as a PC) that the SIM225 is bus powered and requires up to 500mA of power from the USB port. The USB VID will be 0x045B (registered exclusively to Renesas) and USB PID of 0x0025.
Page 23: Graphic Lcd Display
SIM225 Technical Reference Manual GRAPHIC LCD DISPLAY The LCD display (or “glass”) on the SIM225 is a 4.3” diagonal active area 480x272 TFT with optional 4-wire resistive touch layer. Features include: Parameter Typical Value Type TFT TRANSMISSIVE Active Area 95.04×53.86 mm...
Page 24: Touch
LCD output very inexpensively with excellent visual results. The LCD panel has two timing modes: VSYNC/HSYNC mode and DEN mode. The SIM225 uses DEN mode which provides better Direct Drive performance and uses less pins and software overhead than VSYNC/HSYNC mode.
Page 25 Basic touch testing requires only the ADC pins. The ADC pins, connected through current-limiting resistors to the touch panel, can be configured dynamically by software to be low current outputs or ADC inputs. To do a basic “are we touched?” test on the SIM225, the pins can be configured as follows: Signal...
Page 26 Since the touch planes can have resistance as low as 200Ω, up to 16mA is required to drive them – beyond the capability of the RX digital outputs. Therefore the SIM225 has a set of four higher-current output drivers with the following signals directly wired through the drivers from the MCU...

500mA to power the board. On the schematics, this supply is denoted +5V_USBF. In the USB-only powered mode the SIM225’s total power is limited to 500mA: only the extra power not consumed by the SIM225 will be available for battery charging. This may result in long charge times.
Page 29: Turning Sim225 Off: The Pwrdwn# Signal
Lithium batteries, including carefully following the recommendations in the TI BQ24030 documentation. LIPO CONNECTION The SIM225 supports single cell 3.7V LiPo batteries with two or three wires (power, ground, and optional temperature sensor). These three signals are available on both the LiPo Battery/Switch Connector Baseboard Connector.
Page 30 USB port will not exceed 500mA, so whatever power is left over from powering the SIM225 will charge the battery. The amount of time taken to charge the battery is dependent on many factors, but the less power available to the charging circuit the longer it will take to charge the battery.
Page 31 BATTERY LEVEL MEASUREMENT Measuring the true current charge on a battery is quite challenging. As a balance between cost and accuracy, the SIM225 has a simple method to determine the current voltage on the LiPo battery. A simple high-side switch (Diodes Inc.

USB Mini-B power input: SIM or even connected equipment such as a PC or USB Hub. The 500mA limit on +5_USBF is lower than some variants, for example the SIM225-A00 with 0.7W audio amplifier/speaker, require for their complete functionality. Turning on some features without sufficient power may cause a system reset.
Page 33: Usb Host Power
SIM225 Technical Reference Manual USB HOST POWER In SIM225 variants with LiPo support (such as the SIM225-A00), there is no assurance that the main operating power source is +5VDC; often as the battery drains, the main supply voltage will drop below 4.0 volts.
Page 34: Memory
The SDRAM, when used with the MCU’s Direct Drive DMA and Timer peripherals, can deliver pixel data directly to the SIM225’s LCD screen. During the delivery of pixel data to the LCD, software in the MCU must be cautious not to access the SDRAM or visible timing artifacts can appear on the screen.
Page 35: Eeprom
-A04 8 Megabytes 512KB x 16 EEPROM The SIM225 features a 2Kbit (256 byte) On Semiconductor CAT34C02 EEPROM with software write protection features. The EEPROM is an I2C device on the RX MCU’s RIIC1 port and shares an I2C connection with the Temperature Sensor chip.
Page 36: Universial Serial Bus (Usb)
All others UNIVERSIAL SERIAL BUS (USB) All SIM225 variants have a single USB 2.0 Full Speed (12Mbit/s) device (or “function”) capability, though not all variants have the associated mini-B connector. The USB Device signals are also available on other connectors, including the PCB Edge Connector and the Baseboard Connector (when present).

Page 40: Speaker/Amplifier
TEMPERATURE SENSING MCU ON-CHIP TEMPERATURE SENSOR The SIM225’s MCU contains an on-chip temperature sensor, readable by the on-chip 12 bit ADC with a typical accuracy of +/- 1%. This sensor may be suitable for keeping track of general system temperature, but is not an accurate ambient air temperature sensor.
Page 41: Clocks, Oscillators, And Time Keeping
A real time clock/calendar which keeps track of the correct time/date as set by the end user or some other means. There are many producers and consumers of stable clock signals (or “clocks”) on the SIM225. All clocks – including, for instance, the 96MHz CPU core clock, the 12MHz USB clock, and a 9,600baud serial port clock –...
Page 42: Cpu And Peripheral Clocks
USB ports, 9600 baud for a UART serial port, 48MHz for the SRAM bus, etc. While the RX63x MCU family used on the SIM225 can operate up to 100MHz, on the SIM225 it should typically be programmed to operate at 96MHz so that all the other peripherals can divide down properly from that top frequency. The complexity and capabilities of the RX family clock system are beyond the scope of this guide: consult the Renesas documentation for a complete description.
Page 43: User Pushbutton Switch And Leds
Some SIM225 variants have two bi-color red-green LEDs placed on front of the display-side of the module. A bi-color LED is actually two independent LEDs in one package: the LED on the SIM225 has red and green LEDs that, when both are on, have an amber hue. Typically, a plastic or metal front panel enclosure will expose this LED through a plastic light pipe;...
Page 44: Connectors
SIM225 (and most common across various sizes and families of SIMs), the SIM225 Baseboard Connector is one of the most flexible off-module connectors available and exposes many more signals. Often a simple 2-layer PCB daughter-card will be attached to the SIM225 using this connector to adapt the SIM225 to a particular system environment.
Page 45: Pcb Edge Connector
P03/DA0 Ground Ground There is no legacy full-level RS232 port on the SIM225 however a simple and inexpensive adaptor (such as CircuitMonkey.com USB-Serial TTL Adapter) can be easily attached to the one of the Baseboard Connector’s UARTs to enable full serial-over-USB communications to a PC. Alternatively, a common...
Page 46 SPA100 may be required to reprogram SIM225 variants that do not have the JTAG Connector and/or USB Mini-B Device Connector. Some SIM225 variants have the extended version of the PCB Edge Connector exposing additional signals: RX631/63N RX621/62N Signal Description...
