Overview

The MKV31F256VLL12 is a high-performance ARM Cortex-M4 microcontroller from NXP's Kinetis V series, operating at up to 120MHz. Specifically optimized for motor control and power conversion, it features a Floating Point Unit (FPU), dual 16-bit ADCs, and 256KB of Flash memory in a 100-LQFP package.

Why Choose This Part

This MCU provides a significant performance boost for math-intensive control loops thanks to its integrated FPU and DSP instructions. The dual 16-bit ADCs allow for simultaneous sampling of phase currents and voltages, which is critical for high-accuracy motor positioning and torque control.

Applications

Brushless DC (BLDC) Motor Control
Utilizes the 120MHz Cortex-M4 core and high-speed ADCs for precise sensorless vector control.
Uninterruptible Power Supplies (UPS)
Manages complex power switching cycles using dedicated PWM timers and fast analog-to-digital conversion.
Industrial Pump and Fan Control
Implements efficient variable frequency drives for industrial fluid and air management systems.
Permanent Magnet Synchronous Motor (PMSM) Drives
Leverages DSP instructions and FPU to execute field-oriented control (FOC) algorithms with low latency.
