EVAL-M3-302F User Guide
iMOTION™ Modular Application Design Kit
About this document
Scope and purpose
This User Guide provides an overview of the evaluation board EVAL-M3-302F including its main features, key
data, pin assignments and mechanical dimensions.
EVAL-M3-302F is an evaluation board as part of the iMOTION™ modular application design kit (MADK). This
board features and demonstrates Infineon's advanced motion control engine (MCE 2.0) technology for
permanent magnet motor drives over the full speed range.
The evaluation board EVAL-M3-302F was developed to support customers during their first steps designing
applications using permanent magnet motors via sensorless sinusoidal control.
The IMC302A contains two cores - the Motion Control Engine (MCE) and an additional microcontroller (MCU).
MCE support files and documentation will be available from the Infineon website. The MCU core-related CMSIS
pack can be downloaded from the KEIL IDE and this document does not cover those topics.
Intended audience
This User Guide is intended for all technical specialists who have a knowledge of motor control and high-power
electronics converters. The board is intended for use under laboratory conditions.
This board will be used during design in, for evaluation and measurement of characteristics, and proof of data
sheet specifications.
Note:
PCB and auxiliary circuits are NOT optimized for final customer design.
