Description
The Atmel SAM7X512/256/128 is a highly-integrated Flash microcontroller based on 
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. 
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
®
 wireless networks.
