AT91SAM7XC512B-CU

The SMART SAM7XC512 is a member of a series of highly integrated Flash microcontrollers based on the 32-bit ARM RISC processor. It features 512 Kbytes of high-speed Flash and 128 Kbytes of SRAM, an extensive peripheral set, including an 802.3 Ethernet MAC, a CAN controller, an AES128 encryption accelerator and a TDES. 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 SAM7XC512 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.
