Description
Atmel's SAM7X512/256/128 is a member of a series of highly integrated Flash microcontrollers
based on the 32-bit ARM RISC processor. It features 512/256/128 Kbytes 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 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, for example, Ethernet, CAN wired and Zigbee
wireless
networks.
