Infineon PSOC Control C3 MCUs with Arm Cortex-M33 for Motor Control and Power Conversion

Infineon Technologies AG has introduced the PSOC Control C3 series microcontrollers (MCUs), based on the Arm Cortex-M33 core, for motor control and power conversion applications. Supported by the ModusToolbox software environment, these MCUs offer a scalable range of performance, features, and memory options. The series includes Entry Line (C3P2, C3M2) and Main Line (C3P5, C3M5) devices, providing flexibility for various system requirements.

The Entry Line MCUs feature high-resolution and high-precision A/D converters and timers, while the Main Line variants add high-resolution Pulse Width Modulation (HRPWM) for precise motor and power control. With real-time event response and integrated memory, these MCUs optimize system efficiency while supporting multiple communication interfaces for broader application compatibility.

All PSOC Control C3 MCUs are designed for executing power and motor control loops, with the Main Line models offering higher switching frequencies and compatibility with Wide Bandgap (WBG) power systems. Their low-latency architecture and efficient resource utilization make them well-suited for high-performance motor drive and power conversion applications.
