KV4x: Kinetis KV4x-168 MHz, High Performance Motor / Power Conversion MCUs based on Arm^® Cortex^®-M4

Overview

The Kinetis^® KV4x family of MCUs is a high-performance solution offering exceptional precision, sensing, and control for some of the most demanding applications in motor and power control. Built upon the Arm^® Cortex^®-M4 core running at 168 MHz with DSP and floating point unit, it features advanced high-speed and high-accuracy peripherals such as high-resolution pulse-width modulation (PWM) with 312 picosecond resolution, dual 12-bit analog-to-digital converters (ADCs) sampling at 4.1 mega samples per second (MSPS), a total of 30 PWM channels for support of multi-motor systems and dual FlexCAN modules. To maximize execution performance a 128-bit wide flash interface is utilized. The Kinetis KV4x MCU family is supported by a comprehensive enablement suite from NXP^® and third-party resources including reference designs, software libraries, and motor configuration tools.

Features

168 MHz Cortex-M4 core with DSP, floating point unit – improves performance in math-intensive applications (e.g., processing of sensorless FOC (field oriented control) algorithms)
128-bit wide flash interface with a cache to minimize the number of wait states while executing fast control loops
2x 12-bit, 16-channel ADCs with PGAs – 4.1 MSPS ideal for digital power conversion or for motor control applications
Up to 12 channel eFlexPWM – up to 312ps resolution for demanding digital power conversion applications
Up to 2 x 8-channel and 1 x 2-channel programmable FlexTimers – high-accuracy PWM generation with integrated power factor correction or speed sensor decoder (incremental decoder/hall sensor)
Quadrature encoder/decoder
Up to 2 FlexCAN modules – high-speed, high-reliability industrial communication
Broad family scalability with hardware and software compatibility – easy migration to more performance, memory and feature integration within the Kinetis^® V series
