IRMCF371 is a high performance RAM based motion control IC designed primarily for appliance applications. IRMCF371 is esigned to achieve low cost and high performance control solutions for advanced inverterized appliance motor  ontrol.

IRMCF371 contains two computation engines. One is Motion Control Engine (MCETM) for sensorless control of  ermanent agnet motors; the other is an 8-bit high-speed microcontroller (8051). Both computation engines are  ntegrated into one onolithic chip. The MCETM contains a collection of control elements such as Proportional plus Integral, Vector rotator, Angle stimator, Multiply/Divide, Low loss SVPWM, Single Shunt IFB. The user can program a motion control algorithm by onnecting these control elements using a graphic compiler. Key components of the sensorless control algorithms, such as the ngle Estimator, are provided as complete pre-defined control blocks implemented in hardware. A unique  nalog/digital circuit nd algorithm to fully support single shunt current reconstruction is also provided. The 8051  icrocontroller performs 2-cycle nstruction execution (60MIPS at 120MHz). The MCE and 8051 microcontroller are connected via dual port RAM to  rocess ignal monitoring and command input. An advanced graphic compiler for the MCETM is seamlessly integrated into the ATLAB/Simulink environment, while third party JTAG based emulator tools are supported for 8051 developments. IRMCF371 omes with a small QFP48 pin lead-free package.
