A2F500M3G-FG256M [Microchip]

The SmartFusion cSoC combines a hard 50MHz 32-bit ARM Cortex-M3 microcontroller with FPGA fabric, embedded nonvolatile memory, and programmable analog components including ADCs, DACs, and signal conditioning blocks. It offers features like secure ISP with 128-bit AES, FlashLock for FPGA security, and operates across military temperature range (-55°C to 125°C). Key benefits include embedded SRAMs and FIFOs, multiple clock conditioning circuits, and a variety of I/O interfaces.
