NXP | MC9S12XS64CAE

The new S12XS family of 16-bit micro controllers is a compatible, reduced version of the S12XE family. These families provide an easy approach to develop common platforms from low-end to high-end applications, minimizing the redesign of software and hardware.

The S12XS family delivers 32-bit performance with all the advantages and efficiencies of a 16-bit MCU while
retaining the low cost, power consumption, EMC and code-size efficiency advantages currently enjoyed by users of Freescale’s existing 16-bit S12 and S12X MCU families. Like members of other S12X families, the S12XS family runs 16-bit wide accesses without wait states for all peripherals and memories.
