Overview

The MKV31F512VLL12 is a high-performance Kinetis KV series microcontroller powered by a 120MHz ARM Cortex-M4 core with a Floating Point Unit (FPU). Designed specifically for motor control and power conversion applications, it features 512KB of Flash, 96KB of SRAM, and dual 16-bit ADCs for high-speed signal acquisition.

Why Choose This Part

The inclusion of an FPU and DSP instructions allows for complex mathematical computations in a single cycle, which is critical for real-time control loops. It offers a rich set of peripherals including dual 16-bit ADCs and a hardware random number generator, all while maintaining low power consumption with a shutdown current as low as 0.14uA.

Applications

Brushless DC (BLDC) Motor Control
Utilizes the 120MHz CPU and hardware math acceleration for precise sensorless or sensored motor commutation.
Permanent Magnet Synchronous Motors (PMSM)
The integrated FPU and DSP instructions enable efficient execution of Field Oriented Control (FOC) algorithms.
Industrial Inverters
High-speed ADCs and PWM timers allow for real-time monitoring and control of three-phase power stages.
Uninterruptible Power Supplies (UPS)
Provides the processing overhead and precise timing required for fast-switching power conversion and voltage regulation.
