S12XS Family Pin Assignments 64-pin LQFP Package

Description

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.

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.

The S12XS family is available in 112-pin LQFP, 80-pin QFP, 64-pin LQFP package options and maintains a high level of pin compatibility with the S12XE family. In addition to the I/O ports available in each module, up to 18 further I/O ports are available with interrupt capability allowing Wake-Up from stop or wait modes.

The peripheral set includes MSCAN, SPI, two SCIs, an 8-channel 24-bit periodic interrupt timer, 8- channel 16-bit Timer, 8-channel PWM and up to 16- channel 12-bit ATD converter.

Software controlled peripheral-to-port routing enables access to a flexible mix of the peripheral modules in the lower pin count package options.
