Infineon has expanded its PSOC Control C3 family with the new PSC3M/P6 main line microcontrollers, targeting designs that need multi‑motor control, power conversion and strong security in one MCU. Built around an Arm Cortex‑M33 core running at up to 180 MHz, the devices can drive up to four brushless DC (BLDC) motors from a single chip, in both sensored and sensorless configurations.
The series is aimed at industrial drives, robotics, renewable energy inverters, power supplies, as well as drones, smart home appliances, telecom servers and datacenters. For European manufacturers, the parts offer a way to cut component count while preparing for the EU Cyber Resilience Act (CRA) and the shift toward quantum‑resistant security.
Quad‑motor control and power conversion
The PSC3M/P6 MCUs are designed for applications that demand fast control loops, such as high‑RPM motors, PFC stages and wide‑bandgap‑based power converters. Key capabilities include:
- Quad BLDC motor control using a single MCU
- Support for PFC and high‑speed motor control
- Wide‑bandgap‑ready analog front end for fast, precise measurements
- High functional integration for power supply units
- On‑chip operational amplifiers, USB and I3C interfaces
Within the family, PSC3M6 variants are tuned for motor control, while PSC3P6 focus on power conversion. Package options go up to 100 pins, with a scalable, pin‑compatible portfolio.
Post‑quantum‑ready security and tools
Security is a major focus. The MCUs implement firmware protection aligned with the Commercial National Security Algorithm (CNSA) Suite 2.0 and support PSA Level 3 enablement and DICE‑based architectures. They use SHA‑512 and Leighton‑Micali Signatures (LMS) for secure boot and firmware update verification, helping OEMs prepare for post‑quantum cryptography requirements while staying compliant with CRA.
Infineon supports the family with ModusToolbox™ Power Suite and Motor Suite, offering graphical configuration tools, control libraries and an integrated ecosystem. The ModusToolbox AI Assistant is available to ease migration from existing designs to the PSOC Control platform.
