Typical Applications

• Dual‑Inverter Motor Drives – Control two independent three‑phase inverter motors with synchronized PWM generators and multi‑ADC sampling for current sensing and commutation.
• Motor + PFC Power Conversion – Implement a single inverter motor plus power‑factor correction (PFC) system using integrated PWM, ADC and control timers.
• Industrial Servo and VFD Systems – Use high‑resolution timers, quadrature encoder interfaces and fast ADC channels for closed‑loop speed and torque control.
• Robotics and Motion Control – Leverage multiple PWM channels, PGAs and comparators for precise motor actuation and sensor integration.

Unique Advantages

• Highly integrated motor‑control peripherals: Dual MPWM generators, three PGAs and three 12‑bit ADCs with 24 channels enable compact inverter and PFC designs with minimal external components.
• Deterministic compute with FPU: ARM Cortex‑M4F at 120 MHz with FPU delivers up to 150 DMIPS for real‑time control algorithms and signal processing.
• Comprehensive analog front end: 24 ADC channels at up to 1,500 ksps plus dedicated comparators and PGAs provide flexible, accurate sensor conditioning for current and voltage measurement.
• Low‑overhead data movement: 16‑channel DMA and peripheral‑compatible AES/CRC engines reduce CPU load and improve throughput for secure and efficient operation.
• Extensive I/O and timing resources: Up to 107 configurable I/O pins, multiple timers, QEI and capture/compare channels support complex multi‑motor and encoder interfaces.
• Industrial operating range and packaging: Broad supply range (2.7–5.5 V) and ‑40 to 85 °C rating in a 120‑LQFP package suit robust embedded deployments.
