AT91SAM7X512B-AU Microcontroller IC 16/32-Bit 55MHz 512KB FLASH

Description

Atmel's AT91SAM7X512/256/128 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

and a CAN controller. 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 AT91SAM7X512/256/128 system controller includes a reset controller capable of managing

the power-on sequence of the microcontroller and the complete system. Correct device opera-

tion can be monitored by a built-in brownout detector and a watchdog running off an integrated

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, Timer Counter, RTT

and Analog-to-Digital Converters on a monolithic chip, the AT91SAM7X512/256/128 is a power-

ful device that provides a flexible, cost-effective solution to many embedded control applications

requiring communication over, for example, Ethernet, CAN wired and Zigbee™ wireless

networks
