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
TM
control algorithm using the unique Motion Control Engine (MCE
) for permanent magnet motor.
TM
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
TM
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
