IRMCK343

1 Overview

IRMCK343 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 IRMCK343 provides a built-in closed loop sensorless

control algorithm using the unique Motion Control Engine (MCE

) for permanent magnet motor.

The MCE

consists of a collection of control elements, motion peripherals, a dedicated motion

control sequencer and dual port RAM to map internal signal nodes. IRMCK343 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

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 IRMCK343.

IRMCK343 is intended for volume production purpose and contains 64K bytes of OTP (One Time

Programming) ROM, which can be programmed through a JTAG port. For a development

purpose use, IRMCF343 contains a 48k byte of RAM in place of program OTP to facilitate an

application development work. 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
