irmcf343 4 1 overview irmcf343 is a new international rectifier in tegrated circuit device primarily designed as a one- 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 tm ) for permanent magnet motor. the mce tm consists of a collection of control elements, motion peripherals, a dedicated motion 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 tm 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 irmcf343. irmcf343 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, 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 figure 1. typical application block diagram using irmcf343
