TOWER BOARD FOR MC9S12GN32

A demonstration board for the MC9S12GN32 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. An IO ring around the MCU also provided easy access to all signals. The TWR-S12GN32 operates as a standalone debug tool and can also be combined and used as part of the modular Tower System development platform.
