IRMCF143

High Performance Position Servo

Control IC

Description

IRMCF143 is a high performance Flash based motion control IC designed primarily for position servo applications

based on an incremental encoder. IRMCF143 is designed to achieve low cost yet high performance control

solutions for advanced inverterized servo motor control. IRMCF143 contains two computation engines. One is the

Flexible Motion Control Engine (MCE ) for sinusoidal Field Oriented Control (FOC) of servo motors; the other is

an 8-bit high-speed microcontroller (8051). Both computation engines are integrated into one monolithic chip. The

MCE

contains a collection of control elements implemented in a dedicated computation engine such as

Proportional plus Integral, Vector rotator, Angle estimator, Multiply/Divide, and Low loss SVPWM. The user can

program a motion control algorithm by connecting these control elements using a graphic compiler. A unique

analog/digital circuit and algorithm to fully support two leg shunt current sensing is also provided. The 8051

microcontroller performs 2-cycle instruction execution (15MIPS at 30MHz 8051CLK). The MCE and 8051

microcontroller are connected via dual port RAM for signal monitoring and command input. An advanced graphic

compiler for the MCE is seamlessly integrated into the MATLAB/Simulink environment, while third party JTAG-

based emulator tools are supported for 8051 software development. IRMCF143 comes in a 64 pin QFP package.
