S12ZVH Instrument Cluster reference design


The S12ZVH-REF-V1 is a reference design engineered for being a design base for starting an instrument cluster project, also it helps to reducing Automotive Cluster development time and maximizing engineering resources.

Based on the 16-bit S12 MagniV® S12ZVH mixed-signal microcontrollers, the S12ZVH-REF-V1 provides a production-looking design with impressive integration. The S12ZVH-REF-V1 reference design is not only provided as a hardware reference but also as a software and mechanical design.
