Description
IRMCK341 is a high performance OTP based motion control IC designed primarily for appliance applications. IRMCK341 is designed to achieve low cost and high performance control solutions for advanced inverterized appliance motor control. IRMCK341 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 (16MIPS at 33MHz). 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. IRMCK341 comes with a small QFP64 pin lead-free package.

IRMCK341 1 Overview
IRMCK341 is a new International Rectifier integrated circuit device primarily designed as a onechip solution for complete inverter controlled appliance motor control applications. Unlike a traditional microcontroller or DSP, the IRMCK341 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. IRMCK341 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 IRMCK341. IRMCK341 is intended for volume production purpose and contains 64K bytes of OTP (One Time Programming) ROM, which can be programmed through a JTAG port. For a development purpose use, IRMCF341 contains a 48k byte of RAM in place of program OTP to facilitate an application development work. Both IRMCF341 and IRMCK341 come in the same 64-pin QFP package with identical pin configuration to facilitate PC board layout and transition to mass production
