MKV31F256VLH12R

MCU 32Bit KV31F ARM Cortex M4 RISC 256KB Flash 1.8V/2.5V/3.3V 64Pin LQFP T/R

Overview

The Kinetis® KV3x family of MCUs delivers a high-performance solution for BLDC, PMSM and ACIM motor control applications.

Built upon the Arm® Cortex®-M4 core running at 100 or 120 MHz with DSP instruction set and floating point unit, the KV3 devices feature dual 16-bit analog-to-digital converters ADCs sampling at up to 1.2 mega samples per second MSPS in 12-bit mode, multiple motor control timers, 64 to 512 KB of flash memory and a comprehensive enablement suite from proprietary and third-party resources, including reference designs for ACIM, BLDC and PMSM motor control built on ®"s. Embedded Software libraries and motor configuration tools.

The KV3x family is enabled with Kinetis Motor Suite KMS. KMS is a software solution that enables the rapid configuration of motor drive systems, and accelerates development of the final motor drive application, whilst improving overall motor system performance. KMS simplifies motor control across variable speeds and loads of any type of 3-ph PMSM motor regardless of power level. For more information on Kinetis Motor Suite go to nxp.com/kms
