FEATURES
The TWR-S12G128 is a demonstration board for the MC9S12G128 microcontroller; an
automotive, 16-bit microcontroller focused on low-cost, high-performance in a low pin-count
device.
peripherals and memories. The MC9S12G128 targets automotive applications requiring CAN
or LIN/J2602 communications. Examples include body controllers, occupant detection, etc…
The board is designed to interface to the Freescale Tower System, a modular development
platform which aids in rapid prototyping and tool-reuse. An integrated Open-Source BDM,
software tools, and examples provided with the development board make application
development and debug quick and easy. All MCU signals are available on one or both edge
connectors.
