Application Note

AN2955

Rev. 0, 06/2005

Table of Contents

This application note describes the design of a DC motor

drive based on Freescale’s ColdFire MCF523x

microprocessor. The application design takes advantage

of the enhanced time processing unit (eTPU) module,

which is used as a motor control co-processor. The eTPU

completely handles the motor control processing,

eliminating the microprocessor overhead for other

duties.

The concept of the application is to create a speed and

current closed loop DC driver using an optical, Hall-like

position sensor. It serves as an example of a DC motor

control system design using a Freescale microprocessor

with the eTPU. It also illustrates the usage of dedicated

motor control eTPU functions that are included in the

DC motor control eTPU function set.

This application note also includes basic motor theory,

system design concept, hardware implementation, and

microprocessor and eTPU software design, including the

FreeMASTER visualization tool.
