INTRODUCTION SOFTWARE TOOLS INSTALLATION
The S12VR32 EVB features the S12VR32 microcontroller, an automotive 16-bit MCU
for applications based on motor control relays. The S12VR32 evaluation board
integrates an S12 CPU, a LIN physical interface, a 5 V regulator system to supply the
microcontroller and low-side drivers to control the relay.
This ultra-low-cost development platform also includes a Hall sensor interface, an
external 16 MHz oscillator, a switch button and an onboard OSBDM.
