1. Description

Atmel's AT91SAM7XC512/256/128 is a member of a series of highly integrated Flash microcon-

trollers based on the 32-bit ARM RISC processor. It features 512/256/128 Kbyte high-speed

Flash and 128/64/32 Kbyte SRAM, a large set of peripherals, including an 802.3 Ethernet MAC,

a CAN controller, an AES 128 Encryption accelerator and a Triple Data Encryption System. A

complete set of system functions minimizes the number of external components.

The embedded Flash memory can be programmed in-system via the JTAG-ICE interface or via

a parallel interface on a production programmer prior to mounting. Built-in lock bits and a secu-

rity bit protect the firmware from accidental overwrite and preserve its confidentiality.

The AT91SAM7XC512/256/128 system controller includes a reset controller capable of manag-

ing 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 inte-

grated RC oscillator.

By combining the ARM7TDMI processor with on-chip Flash and SRAM, and a wide range of

peripheral functions, including USART, SPI, CAN Controller, Ethernet MAC, AES 128 accelera-

tor, TDES, Timer Counter, RTT and Analog-to-Digital Converters on a monolithic chip, the

AT91SAM7XC512/256/128 is a powerful device that provides a flexible, cost-effective solution

to many embedded control applications requiring secure communication over, for example,

Ethernet, CAN wired and Zigbee

™

wireless networks.
