1 Overview
chip solution for complete inverter controlled appliance motor control applications. Unlike a
traditional microcontroller or DSP, the IRMCF343 provides a built-in closed loop sensorless
control algorithm using the unique Motion Control Engine (MCE

control sequencer and dual port RAM to map internal signal nodes. IRMCF343 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
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

loaded from external EEPROM for 8051 program execution. For high volume production,
IRMCK343 contains OTP ROM in place of program RAM to reduce the cost. Both IRMCF343 and
IRMCK343 come in the same 64-pin QFP package with identical pin configuration to facilitate PC
board layout and transition to mass production
