ARM-based Flash MCU SAM7X512 / SAM7X256 / SAM7X128 SUMMARY DATASHEET 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. Builtin 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.
