Description
The Atmel SAM7X512/256/128 is a highly-integrated Flash microcontroller based on
the 32-bit ARM
the 32-bit ARM
®
RISC processor. It features 512/256/128 Kbytes of high-speed Flash
and 128/64/32 Kbytes of 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.

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

The SAM7X512/256/128 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.

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
SAM7X512/256/128 is a powerful device that provides a flexible, cost-effective solution
to many embedded control applications requiring communication over Ethernet, wired
CAN and ZigBee
