Product Overview

The TWR-S12G128-KIT is a tower system kit for the MC9S12G128 microcontroller. The MC9S12G128 is an automotive, 16bit microcontroller focused on low cost, high performance in a low pin count device. The MC9S12G128 provides 16bit wide accesses, without wait states, for all peripherals and memories. The MCU targets automotive applications requiring CAN or LIN/J2602 communications. Examples include body controllers, occupant detection. The module is designed to interface to the 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 tower system module to make application development and debug quick and easy. All MCU signals are available on one or both edge connectors. The TWR-S12G128 operates as a standalone debug tool and can also be combined and used as part of the modular tower system development platform.
