Page 7: Electrostatic Warning
Kit Contents Electrostatic Warning The SAM3U-EK board is shipped in a protective anti-static package. The board must not be subjected to high electrostatic potentials. A grounding strap or similar protective device should be worn when han- dling the board. Avoid touching the components or any other metallic element of the board. -
Page 8: Power Up
The on-board NAND Flash contains “SAM3U-EK DevStart”. It is stored in the “SAM3U-EK DevStart” folder on the USB Flash disk available when the SAM3U-EK is connected to a host computer and you click on the Flash Disk icon of the on-board demo. -

Page 11: Features List
3x32 bit PIO connection interfaces (PIOA, PIOB, PIOC) Function Blocks 4.3.1 Processor The SAM3U-EK is equipped with a SAM3U4E in LQFP144 package. 4.3.2 Memory The SAM3U4E chip embeds: 256 Kbytes of embedded Flash 48 Kbytes of embedded SRAM with dual bank 16 Kbytes of ROM with embedded bootloader routines (UART, USB) and IAP (In-Application Programming functions) routines. - Page 12 The SAM3U4E features an External Bus Interface (EBI) that permits interfacing to a broad range of external memories and virtually to any parallel peripheral. The SAM3U-EK board is equipped with two kinds of memory devices connected to the SAM3U4E EBI: One PSRAM (Micron MT45V512KW16PEGA 512K*16, 48-ball VFBGA), 16 bits data interface One NAND-Flash MT29F2G16ABD.

Page 13: Clock Circuitry
A 96 to 192 MHz programmable PLL (input from 8 to 16 MHz), capable of providing the clock MCK to the processor and to the peripherals. The SAM3U-EK board is equipped with one 12 MHz crystal, one 32,768 Hz crystal and an external clock input connector (optional, not populated by default). -
Page 14: Reset And Wake-Up Circuitry
The NRST pin integrates a permanent pull-up resistor of about 100 kOhm to VDDIO. On the SAM3U-EK board, the NRST signal is connected to the LCD module and JTAG port. The NRSTB pin is an input-only signal that enables the asynchronous reset of the SAM3U4E series when asserted low. -
Page 15: Power Supply And Management
4.3.5 Power Supply and Management The SAM3U-EK board is supplied with an external 5V DC block through input J11. Protection circuitry is obtained by a PolyZen diode MN13 and an LC combinatory filter MN14. The adjustable LDO regulator MN12 is employed for the main supply of the 3.3V rail. It powers all the 3.3V board components. -
Page 16: Uart
USART is also associated with PDC channels for TX/RX data access. There are 3 USARTs on the SAM3U4E device, SAM3U-EK connects the USART1 bus (including TXD, RXD, RTS, CTS handshake signals control) to the DB9 male connector J4 through the RS232 Trans- ceiver MN7. -

4.3.9 LCD, Backlight Control and Touch Panel SAM3U-EK carries one TFT/Transmissive LCD module with touch screen, FTM280C12D, with inte- grated driver IC HX8347. The LCD display size is 2.8 inches, with a native resolution of 240 x 320 pixels. SAM3U-EK Development Board User Guide... - Page 18 BP1. The LCD chip select signal is connected to NCS2 (a dedicated jumper can disable it, making NCS2 available for other custom usage). The SAM3U4E communicates with the LCD through PIOB where a 16-bit parallel “8080-like” protocol data bus has to be implemented by software. SAM3U-EK Development Board User Guide 6478B–ATARM–05-Oct-09...
- Page 19 The LCD module integrates a 4-wire touch screen panel controlled by MN5, ADS7843, which is a slave device on the SAM3U4E SPI bus. The ADS7843 touch ADC auxiliary inputs IN3/IN4 are connected to test points for optional function extension. 4-10 SAM3U-EK Development Board User Guide 6478B–ATARM–05-Oct-09...

Page 20: Jtag
4.3.10 JTAG A standard 20-pin JTAG connector is implemented on the SAM3U-EK for any ARM JTAG emulator con- nection, such as SAM-ICE. Note that the NRST net is connected to the system button BP1, and is also used to reset the LCD mod- ule. - Page 21 The bit clock is shared; it can be the SSC transmitter clock (TK) or the receiver clock (RK). The default setting on SAM3U-EK is TK and RK shorted together through R97/R99. Please note that trying different ADC/DAC rates would mean different RK/TK rates; this default setting can be modified.
