2 Device overview S12ZVC family

The MC9S12ZVC family is a new member of the S12 MagniV product line integrating a battery level (12 V) voltage

regulator, supply voltage monitoring, high voltage inputs, and a CAN physical interface. It’s primarily targeting at CAN

nodes like sensors, switch panels, or small actuators. It offers various low-power modes and wake-up management to address

state of the art power consumption requirements.

Some members of the MC9S12ZVC family are also offered for high temperature applications requiring AEC-Q100 Grade 0

(-40°C to +150°C ambient operating temperature range). The MC9S12ZVC family is based on the enhanced performance,

linear address space S12Z core and delivers an optimized solution with the integration of several key system components into

a single device, optimizing system architecture and achieving significant space savings.

4 Software tools installation

This section describes how to get started with the S12ZVC board by installing CodeWarrior development studio and testing

the demo program that comes programmed with the board.

4.1 Install CodeWarrior development studio

Freescale’s CodeWarrior for MCUs integrates the development tools for several architectures, including the S12Z

architecture, into a single product based on the Eclipse open development platform. Eclipse offers an excellent framework for

building software development environments and is a standard framework used by many embedded software vendors.

The latest version of CodeWarrior for MCUs (Eclipse IDE) can be downloaded from freescale.com/codewarrior.

4.2 Launch the demo program

The S12ZVC EVB board comes preprogrammed with a small demonstration application that exercises the different modules

of the S12ZVC MCU family, including the ADC, SCI, I2C, and GPIO modules.

To see this demonstration:

1. Connect a 12 V power source to the EVB.

2. Connect a USB cable to the USB type B connector.

3. Press the keys on the keypad to hear tones on the buzzer.

4. Tilt the EVB to observe changes on the red and green LEDs.

5. Rotate the potentiometer to observe changes on the orange LED.

6. Notice that the pressure sensor controls the yellow LED.

7. Set up a terminal program to the OSBDM CDC serial port. Set it to a 9600 baud rate and press any key; you will get a

menu to read temperature and humidity from the I2C sensor.

The software for this application is available on freescale.com.
