IRMCF143S
High Performance Position Servo
Control IC
Description
IRMCF143S is a high performance Flash based motion control IC designed primarily for position servo
applications based on an incremental encoder. IRMCF143S is designed to achieve low cost yet high performance
control solutions for advanced inverterized servo motor control. IRMCF143S 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. IRMCF143S comes in a 64 pin QFP
package.
