Description
IRMCF341 is a high performance RAM based motion control IC designed primarily for appliance applications. IRMCF341 is designed
to achieve low cost and high performance control solutions for advanced inverterized appliance motor control. IRMCF341 contains
two computation engines. One is the 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 implemented in hardware such as Proportional plus Integral, Vector rotator, Angle estimator,
Multiply/Divide, Low loss SVPWM and Single Shunt IFB. The user can program a motion control algorithm by connecting these
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 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 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 developments. IRMCF341 comes in a small QFP64 pin package.
