MCF8329 Evaluation Module
Description
The MCF8329EVM allows users to evaluate the
performance of a MCF8329 motor driver. The EVM
includes an onboard FTDI chip to convert USB
communication, from the micro-USB connector, into
UART. An onboard MSP430FR2355 microcontroller
(MCU) translates the UART communication into either
control signals or SPI formatted data, which is
sent to the MCF8329 device. There are many user-
selectable jumpers, resistors, connectors, and test
points to assist with evaluating the many features of
the MCF8329 IC and the configurable device-specific
settings.
