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 (MCETM) 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
MCETM 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 MCETM 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.

IRMCF143
1 Overview
IRMCF143 is a new generation International Rectifier integrated circuit device primarily designed as a one-chip
solution for complete inverter controlled position servo motor control applications. Unlike a traditional
microcontroller or DSP, the IRMCK401 provides a built-in encoder interface and associated Field Oriented
Control algorithm using the unique Flexible Motion Control Engine (MCETM) for a permanent magnet motor. It
contains a flexible 24bit position counter, and separate position capture/compare unit to facilitate indexing
function. 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. IRMCK401 also employs additional PWM unit to
control a brake IGBT. 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 IRMCF143.
IRMCF143 contains 64K bytes of Flash program memory and comes in a 64-pin QFP package.
