PMSM/BLDC motor controller with additional 8-bit microcontroller iMOTION™ IRMC motor controller with Motion Control Engine (MCE 1.0) and 8051 MCU in QFP-48 package. The IRMCF171 is a flexible control solution for variable speed drives based on a dual core device. The motor controller performs sensor less field oriented control (FOC) for a variable speed drive based on a permanent magnet synchronous motor (PMSM). The integrated MCU is based on an 8-bit 8051 core and is used to implement customer functionality.
