Device Overview MC9S12G-Family
Revision History
1.1 Introduction
The MC9S12G-Family is an optimized, automotive, 16-bit microcontroller product line focused on
low-cost, high-performance, and low pin-count. This family is intended to bridge between high-end 8-bit
microcontrollers and high-performance 16-bit microcontrollers, such as the MC9S12XS-Family. The
MC9S12G-Family is targeted at generic automotive applications requiring CAN or LIN/J2602
communication. Typical examples of these applications include body controllers, occupant detection, door
modules, seat controllers, RKE receivers, smart actuators, lighting modules, and smart junction boxes.
The MC9S12G-Family uses many of the same features found on the MC9S12XS- and MC9S12P-Family,
including error correction code (ECC) on flash memory, a fast analog-to-digital converter (ADC) and a
frequency modulated phase locked loop (IPLL) that improves the EMC performance.
