Description
IRMCF171 is a high performance flash memory based motion control IC designed primarily for appliance applications. IRMCF171 is designed to achieve low cost yet high performance control solutions for advanced inverterized appliance motor control. IRMCF171 contains two computation engines integrated into one monolithic chip. One is the Flexible Motion Control Engine (MCETM) for sensorless control of permanent magnet or induction motors; the other is an 8-bit high-speed microcontroller (8051). The user can program a motion control algorithm by connecting control elements using a graphic compiler. Key components of the complex sensorless control algorithms, such as the Angle Estimator, are provided as complete pre-defined control blocks. A unique analog/digital circuit and algorithm fully supports single or leg shunt current reconstruction. The MCE and 8051 microcontroller communicate via dual port RAM for 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 software development including a flash programmer. IRMCF171 comes in a 48 pin QFP package.
