1 Overview
IRMCF371 is a new International Rectifier integrated circuit device primarily designed as a one-
chip solution for complete inverter controlled appliance motor control applications. Unlike a
traditional microcontroller or DSP, the IRMCF371 provides a built-in closed loop sensorless
control algorithm using the unique Motion Control Engine (MCETM) for permanent magnet motors.
The MCETM consists of a collection of control elements, motion peripherals, a dedicated motion
control sequencer and dual port RAM to map internal signal nodes. IRMCF371 also employs a
unique single shunt current reconstruction circuit to eliminate additional analog/digital circuitry and
enables a direct shunt resistor interface to the IC. Motion control programming is achieved using
a dedicated graphical compiler integrated into the MATLAB/SimulinkTM development environment.
Sequencing, user interface, host communication, and upper layer control tasks can be
implemented in the 8051 high-speed 8-bit microcontroller. The 8051 microcontroller is equipped
with a JTAG port to facilitate emulation and debugging tools. Figure 1 shows a typical application
schematic using the IRMCF371.
IRMCF371 is intended for development purpose and contains 48K bytes of RAM, which can be
loaded from external EEPROM for 8051 program execution. For high volume production,
IRMCK371 contains OTP ROM in place of program RAM to reduce the cost. Both IRMCF371 and
IRMCK371 come in the same 48-pin QFP package with identical pin configuration to facilitate PC
board layout and transition to mass production
