TRK-S12ZVH128
Introduction and Default Settings
The TRK-S12ZVH128 features the
S12ZVH128 MCU, an automotive 16-bit
MCU for instrument cluster applications.
The S12ZVH128 MCU integrates an
S12Z CPU, a CAN physical interface,
a 5 V regulator system to supply the
MCU, four low-power stepper motor
drivers and an LCD controller on-chip.
The TRK-S12ZVH128 board includes
an on-board OSBDM programmer,
a custom 160-segment LCD, CAN
connector (attached to the internal CAN
transceiver), a LIN physical transceiver
as well as an SCI physical transceiver.
The board also features a speaker and
dedicated headers for four low-power
stepper motors.
This guide will show how to quickly
connect the board to a host PC and
execute a demonstration application
preloaded in to the flash memory.
Default jumper positions of the
TRK-S12ZVH128 board are shown
in the figure.

Software Tools Installation
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.
Launch the Demo
Program
The DVD contains a CodeWarrior project
to exercise the different modules of the
S12ZVH MCU family, including the ADC,
TIM, LCD, key interrupts, SCI and CAN
modules.
