About

A Configurable Mixed‑Signal  Arm® Cortex®-M3 Microcontroller Platform

PSOC™ 5LP is Infineon’s flagship Arm Cortex‑M3 solution, combining a 32‑bit CPU with programmable analog and digital hardware on a single chip. This unique architecture allows designers to implement custom peripherals, signal conditioning, and control functions directly in hardware, reducing component count and increasing system flexibility.

Built around the Cortex‑M3 core, PSOC™ 5LP provides deterministic real‑time performance while enabling designers to tailor the device to their specific application requirements. Integrated programmable analog blocks, digital logic, timers, and communication interfaces allow a single device family to address a wide range of use cases, from industrial sensors and control panels to consumer electronics and home appliances.

In addition to PSOC™ 5LP, Infineon’s Cortex‑M3 portfolio includes FM3 microcontrollers, which serve as stable, well‑established solutions for customer designs that prioritize continuity, qualification stability, and long product lifecycles.

What sets the Arm® Cortex®-M3-based MOTIX™ motor control SoC (system-on-chip) apart?

The Arm® Cortex®-M3-based MOTIX™ MCU portfolio delivers motor control system-on-chip (SoC) solutions with an ultra-small footprint. They integrate the microcontroller core, power supply, LIN or CAN (FD) communication interface, and driver stage into a single device - ready for brushed DC (BDC) and brushless DC (BLDC) motor control applications.

The 32‑bit Arm® Cortex®‑M3 CPU architecture, running at up to 60 MHz with up to 256 kB Flash and 32 kB RAM, enables highly efficient real‑time motor control processing.

By consolidating essential motor control functions on a single chip, MOTIX™ motor control SoC solutions deliver clear system-level advantages:

  • Reduced board space through tight integration of motor drive components
  • Lower system cost by minimizing the bill of materials
  • Improved reliability by reducing external components and interconnections
  • Faster development cycles through simplified design and reduced engineering effort

To support your design journey from evaluation to production, Infineon provides comprehensive design-in resources- including software, tools, and application expertise - helping you bring your motor control application to market with confidence.
