High-performance microcontrollers for multi-motor control and power conversion

Infineon is expanding its digital infrastructure portfolio with the release of the PSOC Control C3 Main Line PSC3M/P6 microcontrollers, engineered to govern multi-motor control and power conversion systems. The hardware is deployed across industrial drives, robotics, renewable energy grids, datacenters, and telecommunication servers to manage high-speed switching and complex power topologies.

Architecture for concurrent multi-motor control
The microcontrollers utilize an Arm Cortex-M33 core operating at up to 180 MHz to execute fast control loops required for tight operational precision. By integrating high-speed digital control and precise analog processing, including on-chip operational amplifiers, a single unit can simultaneously drive up to four brushless DC motors in either sensored or sensorless configurations. This processing capability allows the hardware to manage power factor correction and very high-RPM motor applications without requiring an expanded printed circuit board footprint. Furthermore, the architecture is wide-bandgap-ready, enabling the microcontrollers to interface efficiently with next-generation power electronics to improve overall control loop accuracy and system efficiency.

Hardware-level security and cryptography compliance
As connected digital infrastructure faces evolving regulatory requirements, the microcontrollers incorporate robust hardware-level protections to ensure firmware integrity. The components support Platform Security Architecture Level 3 enablement and Device Identifier Composition Engine protocols. Additionally, the microcontrollers comply with post-quantum cryptography requirements outlined in the Commercial National Security Algorithm Suite 2.0. These integrated security mechanisms assist manufacturers in meeting the mandates of the Cyber Resilience Act while securing power supply units and connected devices against emerging cryptographic vulnerabilities in the post-quantum era.

System integration and software deployment
To support deployment across digital healthcare, drones, and smart home appliances, the microcontrollers integrate USB and I3C interfaces for comprehensive system communication. Steve Tateosian, SVP and General Manager of IoT, Consumer and Industrial MCUs at Infineon, notes that the components are designed to meet the industrial demand for faster control loops and improved efficiency in multi-motor configurations. Engineering teams can configure the hardware using the ModusToolbox Power Suite and Motor Suite graphical user interfaces, which provide the unified software frameworks and advanced libraries necessary for system optimization and migration.

Additional Context
This section details technical specifications and competitive benchmarking not included in the original news release.

In the industrial motor control and power conversion sector, the PSC3M/P6 series operates in the same technical category as established real-time microcontrollers such as the Texas Instruments C2000 series and the STMicroelectronics STM32G4 family. Benchmarking in this hardware class relies on measurable parameters including control loop execution time, high-resolution pulse-width modulation capabilities, and analog-to-digital converter sampling rates. The integration of post-quantum cryptographic compliance alongside a 180 MHz Cortex-M33 core provides a specific, measurable standard for evaluating secure firmware execution and multi-motor scalability against conventional mixed-signal microcontrollers that rely on standard cryptographic accelerators.
