The AT91SAM3U features an External Bus Interface (EBI) that permits interfacing to a broad range of external memories and virtually to any parallel peripheral. The EB-SAM3U board is equipped with two kinds of memory devices connected to the SAM3U4E EBI: ·... -
Page 8: 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 EB-SAM3U board is equipped with one 12 MHz crystal, one 32,768 Hz crystal and an external clock input connector (optional, not populated by default). -

The USART is also associated with PDC channels for TX/RX data access. There are 3 USARTs on the SAM3U4E device, EB-SAM3U connects the USART1 bus (including TXD, RXD, RTS, CTS handshake signals control) to the DB9 male connector J3 through the RS232 Transceiver MN6. -
Page 10: Jtag
12 JTAG A standard 20-pin JTAG connector is implemented on the EB-SAM3U for any ARM JTAG emulator connection, such as SAM-ICE. Note that the NRST net is connected to the system button BP1, and is also used to reset the LCD module. -
