MKV31F256VLH12 Description

The NXP MKV31F256VLH12  belongs to the Kinetis KV3x family of MCUs and delivers a high-performance solution for motor control applications (BLDC, PMSM, ACIM). Improves performance for math-intensive applications Simultaneously measures current and voltage phase while reducing jitter on input values and improving system accuracy Easy migration to more performance, memory and feature integration within Kinetis V series Features a comprehensive enablement suite including reference designs, software libraries and motor configuration tools.

MKV31F256VLH12 Features

• 100/120 MHz Cortex-M4 core with DSP and floating point unit – improves performance in math-intensive applications (e.g., processing of sensorless FOC (field oriented control) algorithms)

• 2x 16-bit ADCs with two capture and hold circuits and up to 1.2 MSPS sample rate – simultaneous measurement of current and voltage phase, reduced jitter on input values improving system accuracy

• Up to 2 x 8-channel and 2 x 2-channel programmable FlexTimers – high-accuracy PWM generation with integrated power factor correction or speed sensor decoder (incremental decoder/hall sensor)

• Up to 2 x 12-bit DAC and 2 x ACPMs (analogue comparators) – overcurrent and overvoltage fault detection, reduced BOM costs. ADC and ACMP interconnect with PWM and PDB (programmable delay) blocks for real-time hardware control

• 4- or 16-channel DMA – reduced CPU loading for improved application performance

• Dual watchdogs – compliance with IEC 60730 safety regulation requirements

• Broad family scalability with hardware and software compatibility – easy migration to more performance, memory and feature integration within the Kinetis V series
