IRMCF371

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 (MCE^TM) for permanent magnet motors.

The MCE^TMconsists 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/Simulink^TMdevelopment 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
