MC9S12X256、MC9S12X128、MC9S12X64,pdf datasheet

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.
Targeted at generic automotive applications and CAN nodes, some typical examples of these applications
are: Body Controllers, Occupant Detection, Door Modules, RKE Receivers, Smart Actuators, Lighting
Modules and Smart Junction Boxes amongst many others.
The S12XS family retains many of the features of the S12XE family including Error Correction Code
(ECC) on Flash memory, a separate Data-Flash Module for code or data storage, a Frequency Modulated
Locked Loop (IPLL) that improves the EMC performance and a fast ATD converter.
