Board Description Board overview This chapter introduces the Atmel SAM4E-EK Evaluation Kit design. It introduces system-level concepts, such as power distribution, memory, and interface assignments. ® The SAM4E-EK board is based on the integration of an ARM Cortex™-M4 processor with on-board NAND Flash and a set of popular peripherals.
BNC connector for ADC input • BNC connector for DAC output • User potentiometer connected to the ADC input • ® ZigBee connector • PIO connection interfaces (PIOA, PIOC and PIOD with 32-bit, PIOB with 16-bit, PIOE with 6-bit) SAM4E-EK User Guide 42067B−SAM4E−04/2013...
The SAM4E16 features an External Bus Interface (EBI) that permits interfacing to a broad range of external memories and virtually to any parallel peripheral. The SAM4E-EK board is equipped with one NAND Flash MT29F2G08ABAEA on the EBI. This can change to other type of flash by setting the Static Memory Controller.
Conversely, it can be asserted low from the outside to reset the microcontroller Core and the peripherals. The NRST pin integrates a permanent pull-up resistor of 100kΩ to VDDIO. On the SAM4E-EK board, the NRST signal is connected to the LCD module and JTAG port. Note: At power-on, the NRST signal is asserted with default duration of two clock cycles.
Power supply and management The Atmel SAM4E-EK board is supplied with an external 5V DC block through input J1. It is protected by a PolyZen diode (MN2) and an LC combinatory filter (MN3). The PolyZen is used in the event of an incorrect power supply connection.
DMA interface. The Atmel SAM4E-EK is equipped with a MICREL KSZ8051MNL 10/100 Mbps Fast Ethernet Physical Layer transceiver. It contains the entire physical layer functions of 100BASE-TX as defined by IEEE 802.3u.
CAN1 4.3.11 Display interface The SAM4E-EK carries a TFT transmissive LCD module with touch panel, FTM280C34D. Its integrated driver IC is ILI9325. The LCD display area is 2.8 inches diagonally measured, with a native resolution of 240 x 320 dots.
On the anode drive line, a 0Ω resistor R18 is implemented in series for an optional current limitation. Figure 4-11. Backlight control. MN15 +3V3 AAT3155ITP-T1 PC13 EN/SET LED_A +3V3 OUTCP BN03K314S300R LED_K1 LED_K2 LED_K3 4.7uF LED_K4 LCD BACKLIGHT SAM4E-EK User Guide 42067B−SAM4E−04/2013...
AGND_TP 4.3.13 JTAG/ICE A standard 20-pin JTAG/ICE connector is implemented on the Atmel SAM4E-EK for the connection of a compatible ARM JTAG emulator interface, such as the SAM-ICE™ from Segger. Note that the NRST signal is connected to BP1 system button and is also used to reset the LCD module. The 0Ω...
4.3.14 Audio Interface The Atmel SAM4E-EK evaluation kit supports mono/stereo audio driven by a TPA0223 audio amplifier connected to two DAC channels of the microcontroller. The TPA0223 is a 2W mono Bridge-Tied-Load (BTL) amplifier designed to drive speakers with as low as 4Ω...
Each BNC input has an on-board 50Ω resistor termination that can be applied by closing jumper JP20, JP23 or JP26 • A 10kΩ potentiometer (VR1) is also connected to the AFE0_AD5 implement an easy access to ADC programming and debugging (or implement an analog user control like display brightness, volume, etc.) SAM4E-EK User Guide 42067B−SAM4E−04/2013...
JP21. A filter can be implemented on this output channel by replacing R74 and C69 with appropriate resistor and capacitor values, depending on the application requirements. Figure 4-18. DAC output. JP18 PB14 DAC1 2.2uF JP19 49.9R SAM4E-EK User Guide 42067B−SAM4E−04/2013...
QTouch keys consist in a series of sensors formed by the association of a copper area and the capacitive effect of human fingers approaching it. Keys The Atmel SAM4E-EK implements two individual capacitive touch keys (RIGHT, LEFT). Slider A group of channels forms a Slider. A Slider is composed of eight channels for a QTouch acquisition method. Such a sensor is used to detect a linear finger displacement on a sensitive area.
4.3.19 SD/MMC card The Atmel SAM4E-EK has a high-speed 4-bit multimedia MMC interface, which is connected to a 4-bit SD/MMC micro card slot featuring a card detection switch. Figure 4-21. SD card. +3V3 VDD_MCI SD POWER CTRL R161 SD CARD...
