IRMCF311TR Description

Short technical summary and product information.

The IRMCF311TR from Infineon Technologies is a high-performance, RAM-based motion control IC primarily designed for advanced inverterized appliance motor control solutions. It integrates two computation engines: the MCETM (Motion Control Engine) for high-efficiency sinusoidal sensorless control of permanent magnet AC motors, and an embedded 8-bit high-speed microcontroller (8051) for flexible I/O and man-machine control.

Key electrical specifications include a maximum crystal frequency of 60 MHz, a maximum internal clock frequency of 128 MHz, and a sensorless control computation time of 11 μsec typically. It offers a 12-bit Analog-to-Digital Converter (ADC) with 6 input channels and a conversion speed of 2 μsec, alongside an 8-bit analog output resolution for PWM.

This IC supports both interior and surface permanent magnet motors and includes built-in hardware for single shunt current feedback reconstruction, eliminating the need for external operational amplifiers. It features dual-channel three/two-phase Space Vector PWM and two-channel analog output (PWM). The device is housed in a QFP64 package and supports 1.8V/3.3V CMOS operation.
