Description
IRMCF312 is a high performance RAM based motion control IC designed primarily for appliance applications. IRMCF312 is
designed to achieve low cost and high performance control solutions for advanced inverterized appliance motor control.
IRMCF312 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, SingleShuntIFB, etc., which are implemented in hardware. 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. 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 development. IRMCF312 comes with a small QFP100 pin package.
Preliminary Information
IRMCF312
1 Overview
IRMCF312 is a new International Rectifier integrated circuit device primarily designed as a
one-chip solution for complete inverter controlled appliance dual motor control applications.
Unlike a traditional microcontroller or DSP, the IRMCF312 provides a built-in closed loop
sensorless control algorithm using the unique Motion Control Engine (MCETM) for permanent
magnet motors. 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.
IRMCF312 also employs a unique single shunt current reconstruction circuit to eliminate
additional analog/digital circuitry and enables a direct shunt resistor interface to the IC. The
sensorless control is the same for both motors with a single shunt current sensing capability.
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 IRMCF312.
IRMCF312 contains 48K bytes of RAM, which can be loaded from external EEPROM and is
intended to be used for development purposes. For high volume production, the program RAM
is replaced with 48K bytes of Mask ROM. Both development and mask-ROM versions come
in a 100-pin QFP package with identical pin configuration to facilitate PC board layout and
transition to mass production.
