S12ZVMAEVB QUICK START GUIDE (QSG) ULTRA-RELIABLE MICROCONTROLLERS FOR INDUSTRIAL AND AUTOMOTIVE CONFIDNTIAL AND PROPRIETARY
Get to know the S12ZVMAEVB The S12ZVMA is a programmable single-chip solution for simple loads needed to be controlled in the car remotely via LIN or PWM command.
Step-by-Step Installation Instructions In this quick start guide, you will learn how to set up the S12ZVMAEVB board and run the default exercise. Install Software and Tools 1 Install CodeWarrior Development Studio v11 for S12Z devices. CodeWarrior Dev Tools for MagniV MCUs Connect the USB Cable 2 Connect one end of the USB cable to the PC and the other end to the mini-B connector on the S12ZVMAEVB board. Allow the PC to automatically configure the USB drivers if needed.
Peripheral List The table below shows the components available in the EVB as well as the pin number where it’s connected.

Default Jumper configuration J35 J32 Hall Sensor voltage supply Pin 1-2 Closed Voltage is supplied to Hall sensor using VDDX Pin 2-3 Closed Voltage is supplied to Hall sensor using EVDD pin (PP0) Potenciometer / Temperature Sensor selector Pin 1-2 Closed Potenciometer is routed to PAD3 Pin 2-3 Closed J11 J22 10 Temperature sensor is routed to PAD3 Bootloader Enable Closing this jumper enables the OSBDM to start in bootloader mode.
Default Jumper configuration J21 11 HVI Circuit –Reference Voltage Selector Pin 1-2 Closed - SW1 is connected to VBAT level. This provides a HIGH voltage level when switch SW1 is pressed. Pin 4-6 Closed - SW1 is connected to GND level. This provides a LOW voltage level when switch SW1 is pressed.
Internal Operational Amplifier • The internal amplifier signals of the S12ZVMA EVB are not correctly routed. In order to use the internal amplifier of the S12ZVMA some jumpers need to be open and some external cables connected in order to get the amplifier to work: • Open jumpers: J32, J34 (3-4, 5-6), J38. • External cables: Connected from J38 pin 1 to PAD3 of the header ring, J34 pin 3 to PAD1 of the header ring, J34 pin 5 to PAD2 of the header ring.
