SAM7-P256 development board Users Manual All boards produced by Olimex are ROHS compliant Rev. F, August 2008 Copyright(c) 2010, OLIMEX Ltd, All rights reserved Page 1 INTRODUCTION: Atmel’s AT91SAM7S256 is a member of a series of low pincount Flash microcontrollers based on the 32-bit ARM RISC processor. It features a 256 Kbyte high-speed Flash and a 64 Kbyte SRAM, a large set of peripherals, including a USB 2.0 device, and a complete set of system functions minimizing the number of external components. The device is an ideal migration path for 8-bit microcontroller users looking for additional performance and extended memory. The embedded Flash memory can be programmed in-system via the JTAGICE interface or via a parallel interface on a production programmer prior to mounting. Built-in lock bits and a security bit protect the firmware from accidental overwrite and preserves its confidentiality. The AT91SAM7S256 system controller includes a reset controller capable of managing the power-on sequence of the microcontroller and the complete system. Correct device operation can be monitored by a built-in brownout detector and a watchdog running off an integrated RC oscillator. The AT91SAM7S256 is a general-purpose microcontroller. Its integrated USB Device port makes it an ideal device for peripheral applications requiring connectivity to a PC or cellular phone. Its aggressive price point and high level of integration pushes its scope of use far into the cost-sensitive, high-volume consumer market.

JUMPER DESCRIPTION: Page 11 Description for programming via RS232_0/D COM port, when is SAMBA software The AT91SAM7S256 can be programmed via COM port using the SAM-BATM software. Before being able to use SAM-BA, a recovery procedure, which consists of copying the SAM-BA Boot Assistant into Flash must be performed as follows: 1. Power down the AT91SAM7S256 2. Close jumper TST 3. Power up the AT91SAM7S256 4. Wait 10 sec 5. Power down the AT91SAM7S256 6. Remove jumper TST 7. Power up the AT91SAM7S256 Note: For programming via COM port, you must set jumpers RXD0/DRXD and TXD0/DTXD, according to jumpers description above.
