The S12G is an optimized, 16-bit microcontroller product line focused on low cost, high performance and low pin count. The S12G is suited for generic automotive and industrial applications requiring CAN or LIN/SAE J2602 communication.

The S12G delivers all the advantages and efficiencies of a 16-bit MCU while retaining the cost effectiveness, power consumption, EMC and code-size efficiency advantages currently enjoyed by users of our existing 8-bit and 16-bit MCU families.
