IRMCF312

IRMCF312 is a high performance RAM based motion control IC designed primarily for appliance applications. IRMCF312 is designed to achieve low cost and high performance control solutions for advanced inverterized appliance motor control. IRMCF312 contains two computation engines. One is Motion Control Engine (MCE^TM) 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 MCE^TM contains a collection of control elements such as Proportional plus Integral, Vector rotator, Angle estimator, Multiply/Divide, Low loss SVPWM, SingleShuntIFB, etc., which are implemented in hardware. 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. 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 MCE^TM is seamlessly integrated into the MATLAB/Simulink environment, while third party JTAG based emulator tools are supported for 8051 development. IRMCF312 comes with a small QFP100 pin package.
