Keywords:S12ZVH  MCUs  automotive instrumentation  Voltage Regulator  Battery Sensing 

In this application note, we describe the external hardware required by different modules of S12ZVH family of MCUs. The S12ZVH family was designed to be used in basic/low automotive instrumentation clusters that include analogue stepper motors, an LCD, and/or CAN communications. This application note will cover details on the following modules and pins: the Voltage Regulator, Reset Circuitry, ADC module, Battery Sensing module, high current pins, interrupt pins, unused pins, and the CANPHY module, including its dedicated voltage regulator. This note also covers general PCB layout recommendations that help reduce electromagnetic emissions and improve electromagnetic immunity.

As the S12ZVH family is aimed at automotive instrumentation clusters, we will analyse the different requirements for this application in terms of external hardware required for its operation, and the advantages this family offers over typical solutions.
