HighEnd MCU

The SMART SAM7XC256 is a member of a series of highly integrated Flash microcontrollers based on the 32-bit ARM RISC processor. It features 256 Kbytes of high-speed Flash and 64 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 SAM7XC256 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.
