Introduction
Targeted at automotive multiplexing applications, the MC9S12XD Family will deliver 32-bit performance with all the advantages and efficiencies of a 16-bit MCU. The S12X is designed to retain the low cost, low power consumption, excellent EMC performance and code-size efficiency advantages enjoyed by users of Freescales previous 16-bit MC9S12 MCU family.

Based around an enhanced S12 core, the MC9S12XD Family will deliver two to five times the performance of a 25 MHz S12 whilst retaining a high degree of pin and code compatibility with the original S12D - family.
