MCUs for power conversion and motor control feature PQC
A new microcontroller family boosts real-time control performance for power and motor applications through higher control-loop frequency, accuracy, and system efficiency. This enables the MCUs to meet the needs of applications that require precise, high-speed control for power conversion, including AI server PSUs, EV charging systems, high-end motor control, solar, and switched-mode power supply (SMPS).
Infineon’s PSOC Control C3 Performance Line is based on Arm Cortex-M33 dual-core architecture operating at up to 200 MHz. These MCUs—featuring a programmable power control accelerator (PPCA) hardware accelerator—offer zero-wait-state access to analog and digital peripherals to enable high-performance systems to respond to real-time events with minimal delay.

The PSOC Control C3 MCUs are also wide-bandgap (WBG)-ready with fast, precise analog processing and digital control to improve control-loop accuracy and system efficiency. They support systems designed with WBG switches while achieving best-in-class control loop frequencies, accuracy, and efficiency for applications such as data centers, telecom, solar, and EV charging systems.
“The family is designed for digital control applications that need higher switching frequencies while providing precision, security, and maximum system efficiency,” said Steve Tateosian, senior VP and GM of IoT, consumer, and industrial MCUs at Infineon Technologies.
“As the industry shifts from analog to digital control for power conversion and motor control applications, the PSOC Control C3 Performance Line meets these needs for increased performance, system flexibility, security, and scalability without increasing the footprint,” he added. Tateosian also noted that the MCUs provide high functional integration for multi-output power supplies and low standby power for battery-powered applications.

Security is also a key tenant of these control MCUs for power conversion and motor control applications. The MCUs are compliant with post-quantum cryptography (PQC) requirements for firmware protection outlined in the Commercial National Security Algorithm (CNSA) Suite 2.0.
The CNSA 2.0-compatible MCUs include SHA-512 and LMS firmware verification for secure boot and firmware update verification. These MCUs also support Platform Security Architecture (PSA) Level 3 enablement.
These real-time control MCUs are supported by the ModusToolbox Power Suite and Motor Suite GUI. These unified software and ecosystem platforms aid developers with dedicated tools and advanced libraries.
Samples of the PSOC Control C3 Performance Line MCUs with PQC compliance are available now.
