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.

IRMCF341
1 Overview
IRMCF341 is a new International Rectifier integrated circuit device primarily designed as a one-
chip solution for complete inverter controlled appliance motor control applications. Unlike a
traditional microcontroller or DSP, the IRMCF341 provides a built-in closed loop sensorless
control algorithm using the unique Motion Control Engine (MCETM) for permanent magnet
motors. The MCETM consists of a collection of control elements, motion peripherals, a dedicated
motion control sequencer and dual port RAM to map internal signal nodes. IRMCF341 also
employs a unique single shunt current reconstruction circuit to eliminate additional analog/digital
circuitry and enables a direct shunt resistor interface to the IC. Motion control programming is
achieved using a dedicated graphical compiler integrated into the MATLAB/SimulinkTM
development environment. Sequencing, user interface, host communication, and upper layer
control tasks can be implemented in the 8051 high-speed 8-bit microcontroller. The 8051
microcontroller is equipped with a JTAG port to facilitate emulation and debugging tools. Figure 1
shows a typical application schematic using the IRMCF341.
IRMCF341 contains 48K bytes of program RAM, which can be loaded from external EEPROM
for 8051 program execution. The IRMCF341 is intended for development purposes. For high
volume production, the program RAM is replaced with 64K bytes of OTP ROM. Both the
development and ROM versions come in a 64-pin QFP package with identical pin configuration to
facilitate PC board layout and transition to mass production.
