MC9S12XDP512MAL Description
The MC9S12XD family 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 MC9S12XD family will deliver 2 to 5 times the performance ofa 25-MHz S12 whilst retaining a high degree of pin and code compatibility with the S12.
The MC9S12XD family introduces the performance boosting XGATE module. Using enhanced DMAfunctionality, this parallel processing module offloads the CPU by providing high-speed data processingand transfer between peripheral modules, RAM, Flash EEPROM and I/O ports. Providing up to 80 MIPSof performance additional to the CPU, the XGATE can access all peripherals, Flash EEPROM and theRAM block.
