Description
IRMCK171 is a high performance One Time Programmable ROM based motion control IC designed primarily for appliance applications. IRMCK171 is designed to achieve low cost yet high performance control solutions for advanced inverterized appliance motor control. IRMCK171 contains two computation engines. One is the Flexible Motion Control Engine (MCETM) for sensorless control of permanent magnet motors or induction 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 a dedicated computation engine such as Vector rotator, Arc-Tangent, Multiply/Divide, Low loss SVPWM and Motor current sensing. 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 to fully support single shunt current reconstruction is also provided. The 8051 microcontroller performs 2-cycle instruction execution (16.5MIPS at 33MHz 8051CLK). 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 an OTP programmer. IRMCK171 comes in a 48 pin QFP package.

IRMCK171
1 Overview
IRMCK171 is a new generation 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 IRMCK171 provides a built-in closed loop sensorless control algorithm using the unique flexible Motion Control Engine (MCETM) for permanent magnet motors as well as induction 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. IRMCK171 also employs a unique single shunt current reconstruction circuit in addition to two leg shunt current sensing 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 IRMCK171. IRMCK171 contains 32K bytes of OTP program ROM, The IRMCF171 contains 64K bytes of Flash RAM and intended for development purposes only while the IRMCK171 is intended for volume production. Both the development and ROM versions come in a 48-pin QFP package with identical pin configuration to facilitate PC board layout and transition to mass production.

Note: (1) Data guaranteed by design. (2) To guarantee stability of the operational amplifier, it is recommended to load the output pin by a capacitor of 47pF, see Figure 5. Here only the single shunt current amplifier is show but all op amp outputs should be loaded with this capacitor.
