Product Summary
The MC9S12XS256MAL is a Microcontroller. The MC9S12XS256MAL will retain the low cost, power consumption, EMC and code-size efficiency advantages currently enjoyed by users of Freescale’s existing 16-Bit MC9S12 MCU Family. Based around an enhanced S12 core, the MC9S12XS256MAL will deliver 2 to 5 times the performance of a 25-MHz S12 whilst retaining a high degree of pin and code compatibility with the S12. The MC9S12XS256MAL introduces the performance boosting XGATE module. Using enhanced DMA functionality, this parallel processing module offloads the CPU by providing high-speed data processing and transfer between peripheral modules, RAM, Flash EEPROM and I/O ports. Providing up to 80 MIPS of performance additional to the CPU, the XGATE can access all peripherals, Flash EEPROM and the RAM block.
