Product details
Overview
IMC302AF064XUMA1 from Infineon Technologies is a dual-core motor control IC integrating a dedicated Motion Control Engine (MCE) and an ARM® Cortex®-M0 user application controller. It supports sensorless or Hall-based PMSM/BLDC control, single-leg or leg-shunt current sensing, and integrated boost/totem-pole PFC. Delivers 96 MHz PWM timing, 12-bit ADC (1 MS/s, 7 inputs), and MultiCAN+ (2 nodes, 1 MBaud) for air conditioner and refrigerator compressor drives.
For engineers reviewing the IMC302AF064XUMA1 datasheet, IMC302AF064XUMA1 pinout, IMC302AF064XUMA1 application, or IMC302AF064XUMA1 equivalent, this page provides verified technical context, LQFP-64 package mapping, MCE+MCU functional partitioning, PFC-capable motor control specifications, and validated alternative parts for variable-speed drive design.
Technical Context
The IMC302AF064XUMA1 implements a hardware-accelerated Motion Control Engine (MCE) with built-in space vector PWM, fault protection logic, and script-based I/O control-operating independently from the ARM® Cortex®-M0 core. Its dual-core architecture enables concurrent real-time motor commutation and user application tasks such as communication protocol handling and system supervision.
It supports both single-shunt and leg-shunt current sensing topologies, integrates analog hall sensing inputs (3x), and provides dedicated PFC control blocks for boost and totem-pole configurations. The MCE communicates with the MCU via high-speed JCOM interface, while shared peripherals-including CCU4 timers, USIC channels, and ADC-require coordinated resource allocation per application requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IMC301AF064XUMA1 | Lacks integrated PFC control blocks; no boost/totem-pole PFC hardware acceleration | Suitable only for single-motor systems without power factor correction requirement | Select when PFC is handled externally or omitted entirely to reduce BOM cost |
| IFX9201S | Standalone gate driver IC; no embedded MCU or MCE; requires external controller and ADC | Used in discrete motor control designs where flexibility and component reuse outweigh integration benefits | Select when existing controller architecture prohibits migration to SoC-style motor ICs |
Compared with IMC301AF064XUMA1, the IMC302AF064XUMA1 adds hardware PFC control and associated current sensing interfaces-enabling single-chip solutions for Class B/C appliance compliance. Versus IFX9201S, it replaces multi-chip signal chain complexity with deterministic real-time execution but requires full firmware re-architecture.

FAQ
What is the role of the Motion Control Engine (MCE) in IMC302AF064XUMA1?
The MCE is a dedicated hardware accelerator that executes motor control algorithms-including sensorless field-oriented control, space vector PWM generation, and fault protection-without consuming ARM® Cortex®-M0 CPU cycles. It operates autonomously using pre-configured scripts loaded via MCEWizard, enabling deterministic real-time response down to 100 ns timing resolution for critical safety functions like overcurrent shutdown.
Does IMC302AF064XUMA1 support both boost and totem-pole PFC topologies?
Yes, IMC302AF064XUMA1 integrates configurable hardware blocks for both boost and totem-pole PFC control, including dedicated current sensing inputs, voltage feedback processing, and PWM output routing. The MCE handles PFC loop regulation independently, allowing simultaneous operation with motor control-verified in Infineon's AN2019-09 reference design for combined PFC+motor inverters.
How many PWM outputs does IMC302AF064XUMA1 provide, and what is their maximum frequency?
IMC302AF064XUMA1 provides six dedicated PWM outputs (PWMUL/PWMUH through PWMWL/PWMWH) for 3-phase inverter control, with timing resolution derived from a 96 MHz clock. Each output supports edge- or center-aligned modes, programmable dead time (down to 1 ns steps), and synchronous update-enabling switching frequencies up to 20 kHz with minimal jitter in appliance-grade motor drives.
Is external crystal required for IMC302AF064XUMA1 operation?
No, IMC302AF064XUMA1 includes internal slow (32 kHz) and fast (up to 96 MHz) oscillators sufficient for most motor control applications. An external crystal (4–20 MHz) is optional and used only when higher clock accuracy is needed-for example, in CAN FD timing-critical implementations or synchronized multi-inverter systems requiring sub-microsecond phase alignment.
