Description
IRMCF311 is a high performance RAM based motion control IC designed primarily for appliance applications. IRMCF311 is designed to achieve low cost and high performance control solutions for advanced inverterized appliance motor control. IRMCF311 contains two computation engines. One is 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 such as Proportional plus Integral, Vector rotator, Angle estimator, Multiply/Divide, Low loss SVPWM, Single Shunt IFB. 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 implemented in hardware. 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 MCETM is seamlessly integrated into the MATLAB/Simulink environment, while third party JTAG based emulator tools are supported for 8051 developments. IRMCF311 comes with a small QFP64 pin lead-free package.

IRMCF311 1 Overview
IRMCF311 is a new International Rectifier integrated circuit device primarily designed as a onechip solution for complete inverter controlled air conditioner motor control applications. Unlike a traditional microcontroller or DSP, the IRMCF311 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. IRMCF311 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 schematics using IRMCF311. IRMCF311 is intended for development purpose and contains 48K bytes of RAM, which can be loaded from external EEPROM for 8051 program execution. For high volume production, IRMCK311 contains OTP ROM in place of program RAM to reduce the cost. Both IRMCF311 and IRMCK311 come in the same 64-pin QFP package with identical pin configuration to facilitate PC board layout and transition to mass production
