Nuvoton: M433 CAN/USB FS OTG Series
The Nuvoton NuMicro® M433 Series is engineered to be the high-performance heart of your next motor drive design. Powered by an Arm® Cortex®-M4F core running at 144 MHz, it provides the computational muscle needed for complex Field Oriented Control (FOC) and real-time processing.
Why the M433 is the „Precision Engine“ for Motor Applications:
・Superior PWM Capability: Equipped with up to 18 channels of 16-bit PWM, including Enhanced PWM (EPWM) that supports complementary mode and dead-time insertion.
・Precision Feedback: Features an Enhanced Quadrature Encoder Interface (EQEI) to decode rotation speed and motion information with extreme accuracy.
・High-Speed Sensing: Integrated 5 MSPS 12-bit SAR ADC allows for lightning-fast current and voltage sampling, ensuring responsive control loops.
・Mission-Critical Safety: Built-in Hardware Brake function reacts instantly to system faults (such as clock failure or brown-out), protecting your power switches and mechanical components.
・Efficiency at the Edge: Achieves high performance while maintaining low power consumption, with a deep power-down mode as low as 350 nA.
From industrial automation to smart consumer appliances, the M433 series delivers the reliability and integrated peripherals needed to simplify your BOM and accelerate time-to-market.
