Functional description
Figure 2 shows the block diagram of the EVAL-M3-302F. The IMC302A-F064 provides a built-in, closed loop and
sensorless control algorithm using the unique flexible Motion Control Engine (MCE) for permanent magnet
motors, and additionally a boost or totem pole power factor correction (PFC). The MCE™ consists of a collection
of control elements, motion peripherals, a dedicated motion control sequencer and internal memory to map
internal signal nodes. IMC302A-F064 also employs a unique single shunt current reconstruction circuit in addition
to a leg shunt current sensing circuit to eliminate additional analog/digital circuitry.
The integrated MCU is based on an Arm® Cortex® M0 core. It is internally connected to the MCE via a fast serial
port. The debug interface (SWD) is routed to the on-board debug interface via a galvanic isolation.
