IRMCF343 is a high performance RAM based motion control IC designed primarily for appliance applications. IRMCF343 is designed to achieve low cost and high performance control solutions for advanced inverterized appliance motor control.
IRMCF343 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. IRMCF343 comes with a small QFP64 pin lead-free package.

IRMCS3043无传感器马达驱动平台
Sensorless Motor Drive Platform with Integrated PFC for Appliance Based on iMOTIONTM chipset
IRMCS3043 is a reference design platform for IRMCF343, a high performance RAM-based motion control IC designed primarily for appliance applications, up to 1.7kW continuous input power. It’s mainly aimed to achieve simple, low cost and high performance solutions for advanced appliance motor control. It consists of an active PFC frond-end and an inverter stage, both of which are controlled by the IRMCF343 digital IC simultaneously. The power stage contains a Trench IGBT (IRGP4063DPbF) for the PFC and an integrated power module (IRAMX16UP60A-2) for the inverter, which are part of iMOTIONTM chipset. Users can readily evaluate high performance sensorless control with MCEDesignerTM software without spending development effort usually required in the traditional DSP or microcontroller based system. The complete B/Ms, schematics and layout are provided so that the user can adapt and tailor the design per application needs.
