Freescale 16-bit Core Architectures

S12X
This enhanced HCS12 core provides enhanced EMC performance, additional instructions for improving page capability and code execution of 32-bit calculations. Includes a coprocessor (X-Gate) running at 80 MHz in parallel to S12X Core to increase the MCUs data throughput.
S12
The S12 16-bit processing unit is an industry standard that offers high-speed, a small footprint, and a wide variety of communication and controller interfaces.
HC16
This core is a modular 16-bit CPU with control-oriented digital signal processor capability. It also has a timer processing unit that provides semi-autonomous coprocessor dedicated to performing complex, high-speed timing tasks without CPU intervention.
