1 Introduction
The S12ZVMx12EVB board is designed to drive 3-phase
BLDC or PMSM motors, enabling implementation of motor
control techniques:
• Sensor-less:
• Back-EMF signal sensing using the MCU
integrated ADC modules
• Back-EMF zero-cross signal monitoring using
MCU integrated comparators
• Sensor-based:
• Hall sensor signal monitoring
• Resolver sin/cos signal monitoring
The board features the S12ZVM, a 16-bit automotive
microcontroller from the MagniV family. This System on
Chip integrates an S12Z microcontroller with a Local
Interconnect Network (LIN) physical interface, a 5-V
regulator and a Gate Driver Unit (GDU). The motor power
stage comprises 6 N-channel power MOSFETs that are
controlled by the MCU integrated GDU.
A USB to SCI interface is available and can be used for
FreeMaster PC-based application control. An integrated
OSBDM debugger interface is also provided for easy
programming/debugging of the S12ZVM microcontroller
device.
The board is available in the following versions:
• S12ZVML12EVBLIN – Features the
MC9S12ZVML12, with integrated LINPHY
