Infineon Unveils IMC300 Motor Controller with Integrated Arm Cortex‑M0 for Enhanced Flexibility

Infineon Technologies has launched the IMC300 motor controller series, combining the iMOTION Motion Control Engine with a dedicated Arm Cortex‑M0 microcontroller. This new line expands the existing IMC100 family and delivers the flexibility demanded by variable‑speed drives.

Both IMC100 and IMC300 share the robust MCE 2.0 core, offering turnkey motor control and optional power‑factor correction (PFC). By delegating motor regulation to the MCE, developers can concentrate on higher‑level application logic running on the independent Arm MCU.

The MCE 2.0 delivers highly efficient field‑oriented control (FOC) for permanent‑magnet synchronous motors (PMSM). It consolidates all necessary hardware, software, and protection features, significantly reducing BOM complexity. With a biannual release cadence, the MCE continues to evolve, ensuring cutting‑edge performance.

The integrated Arm Cortex‑M0 MCU offers a versatile peripheral set, supporting system functions, communication protocols, and drive monitoring. IMC300 devices are pre‑certified for functional safety under UL/IEC 60730 Class B, meeting stringent industrial standards.

Variants are available with or without PFC, and the LQFP‑64 packages are already in mass production, while LQFP‑48 units will launch in Q2 2020. Rapid prototyping is supported through two new control boards in the iMOTION Modular Application Design Kit (MADK), which provides modular, flexible development options for drives up to 1 kW.

Infineon will demonstrate the IMC300 series at Embedded World in Nuremberg, showcasing its capabilities to industry professionals.
