IRMCF171
High Performance Sensorless Motor Control IC
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.
