The S12X family will retain the low cost, power consumption, EMC and code-size efficiency advantages currently enjoyed by users of the existing 16-bit HCS12 MCU family. Based around an enhanced HCS12 core, the S12XD family is designed to deliver 2 to 5 times the performance of a 25 MHz HCS12 whilst retaining a high degree of pin and code compatibility with the HCS12. The S12XD family introduces the performance boosting XGATE module. Using enhance DMA functionality, this parallel processing module offloads the CPU by providing high speed data processing and transfer between peripheral modules, RAM and I/O ports. Providing up to 80MIPS of performance additional to the CPU, the XGATE can access all peripherals and the RAM block.
