Description  
IRMCK343 is a high performance OTP based motion control IC designed primarily for appliance applications. IRMCK343 is  
designed to achieve low cost and high performance control solutions for advanced inverterized appliance motor control.  
IRMCK343 contains two computation engines. One is Motion Control Engine (MCETM) for sensorless control of permanent  
magnet motors; the other is an 8-bit high-speed microcontroller (8051). Both computation engines are integrated into one  
monolithic chip. The MCETM contains a collection of control elements such as Proportional plus Integral, Vector rotator, Angle  
estimator, Multiply/Divide, Low loss SVPWM, Single Shunt IFB. The user can program a motion control algorithm by  
connecting these control elements using a graphic compiler. Key components of the sensorless control algorithms, such as the  
Angle Estimator, are provided as complete pre-defined control blocks implemented in hardware. A unique analog/digital circuit  
and algorithm to fully support single shunt current reconstruction is also provided. The 8051 microcontroller performs 2-cycle  
instruction execution (60MIPS at 120MHz). The MCE and 8051 microcontroller are connected via dual port RAM to process  
signal monitoring and command input. An advanced graphic compiler for the MCETM is seamlessly integrated into the  
MATLAB/Simulink environment, while third party JTAG based emulator tools are supported for 8051 developments.  
IRMCK343 comes with a small QFP64 pin lead-free package.
