Infineon’s PSOC™ Control C3 Performance Line sets new standard for real-time control and PQC security

Infineon Technologies AG announced the launch of the PSOC™ Control C3 Performance Line microcontroller family on September 22, 2026. This new family is specifically engineered to enable real-time control in power and motor applications. Infineon highlights these microcontrollers for their ability to deliver high control loop frequency, exceptional accuracy, and enhanced system efficiency.

Built upon an Arm® Cortex®-M33 multi-core architecture, the PSOC™ Control C3 Performance Line is tailored for applications demanding precise, high-speed control in power conversion. Key application areas identified include AI server power supply units, solar systems, switched-mode power supplies (SMPS), electric vehicle charging infrastructure, and high-end motor control systems.

A significant differentiator for this family is its robust support for firmware protection requirements, particularly those related to post-quantum cryptography (PQC). The MCUs are compliant with PQC requirements for firmware protection as outlined in the Commercial National Security Algorithm (CNSA) Suite 2.0 and achieve PSA (Platform Security Architecture) Level 3 enablement. These capabilities are crucial for addressing evolving security needs across various industrial applications and facilitating the transition to increased security in the post-quantum cryptography era.

The Performance Line is optimized for digital control applications that necessitate higher switching frequencies while maintaining precision, security, and overall system efficiency. Infineon emphasizes that these MCUs boost performance, system flexibility, security, and scalability without increasing the physical footprint. This is achieved through proprietary autonomous hardware accelerators combined with high-resolution, high-performing analog peripheral support, enabling superior system performance at high switching frequencies and expanding control-loop bandwidth.
