The TWR-S12G128 is a demonstration board for the MC9S12G128 automotive 16-bit MCUs. 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. Write Code, Download, Evaluate. Yes, that simple!

The TWR-S12G128 is available as a stand-alone module or as a kit (TWR-S12G128-KIT) with the Tower Elevator Modules (TWR-ELEV) and the Tower Prototyping Module (TWR-PROTO). The board is designed to interface to the NXP 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.

TheTWR-S12G128 features the MC9S12G12, a 16-bit MCU focused on low-cost, high-performance, and low pin-count. The MC9S12G Family is intended to bridge the gap between high-end 8-bit MCU’s and high-performance 16-bit MCU’s. The MC9S12GC32CPBE Family is targeted to generic automotive applications requiring CAN or LIN/J2602 communications. This guide will show how to quickly connect the board to a host PC, and execute a demonstration application preloaded into FLASH memory. Default jumper positions for the TWR-S12G128 are shown in the figure below.

Key Applications: Space-constrained applications, Body controllers, Door modules, HVAC, Seat controllers, Smart actuators, RKE receivers, Occupant detection, Lighting modules, Smart junction boxes, Fuel pumps, Oil pumps.
