描述 Description

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 NXP®'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

特性 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 (analog 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
