New microcontrollers combine fast control, advanced security, and flexible peripherals to improve power conversion and motor-control performance across demanding industrial applications with improved overall efficiency.
Infineon Technologies has launched its PSOC Control C3 Performance Line microcontroller family for real-time power conversion and motor-control applications, combining high-speed control with post-quantum security features. The new MCUs target systems including AI server power supplies, solar equipment, switched-mode power supplies, electric vehicle charging, and high-end motor control. Samples of the family are available now.
The devices use a multi-core Arm Cortex-M33 architecture, with variants operating at up to 180 MHz and hardware acceleration enabling higher-performance control. Infineon says the architecture is designed to increase control-loop frequency, accuracy, and system efficiency while responding to real-time events with minimal delay.
For power-conversion designs, the family integrates a Programmable Power Control Accelerator and high-resolution PWM capabilities. Fast analogue and digital peripherals support precise control, while wide-bandgap readiness allows the controllers to work with power stages based on technologies such as silicon carbide and gallium nitride.
Security is another focus. The PSOC Control C3 Performance Line supports Post-Quantum Cryptography requirements associated with CNSA Suite 2.0 and provides PSA Level 3 security enablement. Features include secure boot, protected firmware updates, code protection, and provisions for secure key storage and device attestation.
The portfolio is available in multiple configurations and packages, with dedicated devices for power conversion and motor control. Infineon also supports the MCUs through its ModusToolbox Power Suite and Motor Suite, providing control libraries, development tools, and graphical interfaces for evaluation and system development.
By combining real-time processing, integrated control peripherals, and security functions, the family is positioned for high-frequency switching applications where response time, efficiency, and firmware protection are important design requirements.
