Description

MC9S12XD256VAL is a microcontroller belonging to the MC9S12XD family. It is a low-cost, low-power, and high-performance device that provides enhanced performance compared to the existing 16-bit MC9S12 MCU family. With an enhanced S12 core, it offers 2 to 5 times the performance of a 25-MHz S12 while maintaining pin and code compatibility with the S12. It introduces the performance-boosting XGATE module that offloads the CPU by providing high-speed data processing and transfer between peripheral modules, RAM, Flash EEPROM, and I/O ports. With up to 80 MIPS additional performance to the CPU, the XGATE can access all peripherals, Flash EEPROM, and the RAM block.
