1 Overview
IRMCK341 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 IRMCK341 provides a built-in closed loop sensorless
control algorithm using the unique Motion Control Engine (MCE
The MCE
control sequencer and dual port RAM to map internal signal nodes. IRMCK341 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
schematic using the IRMCK341.
IRMCK341 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, IRMCF341 contains a 48k byte of RAM in place of program OTP to facilitate an
application development work. Both IRMCF341 and IRMCK341 come in the same 64-pin QFP
package with identical pin configuration to facilitate PC board layout and transition to mass
