IRMCF183M
High Performance Sensorless Motor Control IC
Description
IRMCF183M is a high performance Flash based motion control IC designed and optimized for low cost appliance
control which contains two computation engines integrated into one monolithic chip. One is the Flexible Motion
Control Engine (MCE^TM) for sensorless control of permanent magnet motors or induction motors; the other is an
8-bit high-speed microcontroller (8051). The user can program a motion control algorithm by connecting these
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 fully supports single shunt or leg shunt current reconstruction. IRMCF183M comes in a 32 pin 5x5 QFN
package.
Features
 MCE^TM (Flexible Motion Control Engine) -
Dedicated computation engine for high
efficiency sinusoidal sensorless motor control
 Built-in hardware peripheral for single or two
shunt current feedback reconstruction and
analog circuits
 Embedded 8-bit high speed microcontroller
(8051) for flexible I/O and man-machine control
 JTAG programming port for
emulation/debugger
 Serial communication interface (UART)
 Watchdog timer with independent internal clock
 Internal 64Kbyte Flash
 3.3V single supply
