NXP Kinetis KV3x family of microcontrollers is a high-performance solution for BLDC, PMSM and ACIM motor control applications. Built upon the ARM^® Cortex^®-M4 core running at 100/120 MHz with DSP and floating point unit, it features dual-16-bit analog-to-digital converters (ADCs) sampling at up to 1.2 mega samples per second (MSPS), multiple motor control timers, 64 to 512 KB of Flash memory and a comprehensive enablement suite from NXP and third-party resources including reference designs, software libraries, and motor configuration tools.

Features

• 100/120 ARM^®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 (analog comparators) – over-current and over-voltage 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

Applications

• BLDC motors
• PMSM motors
• AC induction motors
