Interfaces: I²C, RS-232, SPI. Supply: 1.62V–1.98V / 3V–3.6V. -40°C to 85°C. 64-LQFP. NRND.","salesMarkdown":"## NRND — plan the last-time buy now This means Infineon is winding down production — new designs should not start with this part, and existing BOM lines need a last-time-buy plan or a qualified replacement. For a production BOM that already uses this part, the procurement path is to secure remaining inventory through the independent channel before availability tightens further. ## Motor controller with on-chip pre-driver The IRMCF311TY is a motor controller from Infineon's MCE™ series, handling commutation and direction management for AC and synchronous motors. Its output configuration is a pre-driver with six half-bridge outputs — one complete three-phase inverter drive stage that directly gates external Power MOSFETs or IGBTs. Primary application target is appliance motor control — think washing machine drums, refrigerator compressors, or HVAC fan drives where sensorless or sensor-based field-oriented control is implemented. ## Supply rails and serial interfaces The dual-rail architecture is typical for mixed-signal motor controllers that keep core voltage low for power efficiency while maintaining 3.3 V compatible I/O for sensor feedback and host communication. Three serial interfaces are available: I²C, RS-232, and SPI. I²C and SPI handle register configuration and parameter tuning; RS-232 provides a direct UART link for host control or debug logging in a panel-mount appliance scenario. ## 64-LQFP with industrial temperature range Packaged in a 64-lead LQFP (also designated 64-QFP in supplier device code), the IRMCF311TY is a surface-mount component with 0.5 mm pitch — a standard footprint for motor control MCUs that balances pin count with board-level inspection capability. Shipping form is tray, not tape-and-reel — factor this into your pick-and-place setup if the line normally runs reel-fed parts.","metaTitle":"IRMCF311TY motor controller, MCE series, NRND, 64-LQFP","metaDescription":"IRMCF311TY MCE series motor controller from Infineon.
