IMC302AF064XUMA1 Overview
An iMOTION motor controller is a mixed-signal IC that offloads the time-critical FOC computation from a software MCU into dedicated hardware. This category fits into the broader hierarchy of motor drive semiconductors -> power management ICs -> mixed-signal ICs -> application-specific microcontrollers. By pairing a deterministic motor control engine with a scriptable Cortex-M0 host, iMOTION parts enable engineers to tune motor parameters without writing low-level real-time code, while still leaving room for application-layer scripting and housekeeping.
Key features include MCE 2.0 hardware FOC, integrated scriptable ARM Cortex-M0 core, configurable PFC control, sensorless and Hall-based motor support, single/leg-shunt current sensing, 3.3 V or 5 V supply operation, integrated gate drivers for an external PFC and inverter stage, and a configurable protection feature set including overcurrent, overvoltage, and overtemperature. UL/IEC 60730 functional-safety support and a programmable scripting engine round out the device. The 64-LQFP package offers ample pin count for multi-channel shunt sensing, PFC driver outputs, and debug interfaces.
Typical applications include white goods (washing machines, refrigerators, dishwashers, air conditioners, fans, pumps), HVAC compressors, and small industrial variable-frequency drives where a compact, energy-efficient BOM is required. The integrated PFC + motor controller shrinks the part count versus discrete solutions, while the MCE 2.0 engine removes the need for a high-performance DSP or Cortex-M4 host MCU.
When designing with this device, follow the Infineon iMOTION hardware design guide for power-stage grounding and shunt-resistor layout to minimize current-sense noise. Use the MCE Designer tool to configure the motor parameters and protection thresholds, and the scripting API for application-layer tasks.

Typical Applications
IMC302AF064XUMA1 is suitable for 6 applications: Washing Machine Direct-Drive Motor Control, HVAC Compressor Variable-Speed Drive, Refrigerator Compressor Drive, Dishwasher Circulation-Pump Drive, Industrial Small-VFD (< 1 kW), Exhaust / Bathroom Fan Controller.
Washing Machine Direct-Drive Motor Control
The IMC302AF064XUMA1 is engineered for direct-drive PMSM and BLDC motors in front-load washing machines, where its MCE 2.0 hardware FOC delivers highly efficient field-oriented control without burdening the Cortex-M0 host MCU. Integrated PFC helps the washer meet IEC 61000-3-2 harmonic limits on the AC mains, while UL/IEC 60730 functional-safety support accelerates compliance with household appliance safety standards. Leg-shunt current sensing lowers BOM cost versus three-shunt topologies. The 64-LQFP package supports multi-speed wash cycles, drum-balancing algorithms, and inverter-driven spin profiles up to 1600 RPM.
Recommended
HVAC Compressor Variable-Speed Drive
For inverter-driven air-conditioner and heat-pump compressors, the IMC302AF064XUMA1 combines sensorless FOC with integrated PFC in a single 64-LQFP IC, eliminating the need for a discrete PFC controller or high-performance MCU. Its MCE 2.0 engine handles compressor-startup transients and low-speed torque ripple deterministically, while the scriptable Cortex-M0 host runs outdoor-unit control logic, expansion-valve sequencing, and Modbus/CAN diagnostics. UL/IEC 60730 functional-safety support simplifies compliance for Class B appliances operating across wide ambient temperatures.
Recommended
Refrigerator Compressor Drive
Refrigerator compressor inverters benefit from the IMC302AF064XUMA1's integrated PFC and sensorless FOC, which together reduce BOM and PCB area in space-constrained compressor drives. The hardware MCE 2.0 engine ensures smooth torque delivery across wide speed ranges, while configurability through MCE Designer lets engineers adapt compressor maps without firmware recompilation. The Cortex-M0 host handles temperature-sensor monitoring, defrost-cycle sequencing, and inverter-protection coordination, keeping the application firmware simple.
Recommended
Dishwasher Circulation-Pump Drive
Dishwasher circulation pumps running on PMSM/BLDC motors can use the IMC302AF064XUMA1 to deliver quiet, efficient variable-speed operation with integrated PFC for harmonic compliance. The leg-shunt current-sensing option enables a compact inverter stage, while configurable protection (overcurrent, overvoltage, overtemperature, locked-rotor) protects the pump from harsh wash-cycle conditions. The scriptable Cortex-M0 host can drive wash-program timing and water-level feedback without an external MCU.
Recommended
Industrial Small-VFD (< 1 kW)
Small industrial variable-frequency drives below 1 kW benefit from the IMC302AF064XUMA1's deterministic FOC engine, integrated PFC, and UL/IEC 60730 functional-safety support in a single 64-LQFP package. The device enables compact panel-mount drives for conveyor motors, small fans, and pumps where size, BOM count, and energy efficiency matter. Single-shunt current sensing minimizes the analog front-end, while MCE Designer lets engineers configure motor parameters in the field without firmware redeployment.
Recommended
Exhaust / Bathroom Fan Controller
Smart bathroom and kitchen exhaust fans with BLDC motors can use the IMC302AF064XUMA1 to deliver quiet variable-speed control with integrated PFC and UL/IEC 60730 safety support. The MCE 2.0 engine handles sensorless or Hall-based FOC, while the Cortex-M0 host runs humidity-sensor integration, occupancy detection, and Modbus communication. The 64-LQFP package accommodates the GPIOs and analog channels needed for humidity/temperature sensors and triac-compatible AC switching.

Key Differentiators
- Integrated PFC + Motor FOC + Cortex-M0 host in single 64-LQFP IC (vs IMC301AF064XUMA1)
- Higher-level scripting via integrated Cortex-M0 + MCE 2.0 (vs TLE95613QXXUMA1)
- Broad Infineon iMOTION ecosystem + MCE Designer toolchain (vs Discrete MCU + gate-driver solution)
Design Notes
Place the IMC302AF064XUMA1's analog ground (AGND) and digital ground (GND) pins connected through a single star-ground point near the shunt resistors. Keep the shunt-resistor traces to IU/IV/IW short and symmetric to minimize current-sense noise that corrupts FOC estimation. Use a 4-layer PCB with a dedicated ground plane; route the PFC current-sense and motor current-sense on separate layers to avoid cross-coupling. Decouple VCC with a 10uF ceramic + 100nF ceramic pair within 5 mm of each supply pin.
Estimated: At 5 V VCC and full MCU + MCE + PFC activity, the IMC302AF064XUMA1's quiescent dissipation is approximately 0.5-0.8 W. The 64-LQFP package has theta_JA of approximately 50 C/W on a 4-layer JEDEC test board, producing a 25-40 C rise above ambient. Add a copper pour under the exposed die-pad area and via-stitch the thermal pad to inner ground planes to keep junction temperature below 125 C in 85 C ambient applications.
Do not assume the IMC302AF064XUMA1's PFC stage can be left unconfigured - leaving the PFC in default state may produce unexpected gate-drive behavior. Always run the MCE Designer tuning workflow before applying inverter output. When migrating from IMC301 to IMC302, recompile the firmware because the integrated PFC register map and protection flags differ between the two parts. Finally, do not exceed the 5.5 V absolute-maximum rating on VCC - the 3.3 V mode requires a clean regulated LDO, not a noisy switching rail.
Place the DC_BUS voltage-sense resistor divider within 10 mm of the DC+ bulk-capacitor node and away from switching nodes to avoid capacitive noise coupling. Route the Hall-sensor inputs (HALL1/2/3) as a tight differential bundle with ground guard traces. The PFC zero-cross detect pin (PFC_ZERO) is sensitive to high-frequency switching noise - add a 100 ns RC low-pass filter if the PFC input is electrically noisy.
