Freescale Kinetis V Microcontrollers

 

Freescale's Kinetis V Series MCUs are based upon the ARM® Cortex®-M0+ and M4 cores and are designed for BLDC, PMSM and ACIM motor control, as well as digital power conversion applications. The Kinetis KV1x family is the entry point and features a 75MHz ARM Cortex-M0+ core with a hardware square root and divide block giving it a 27% increase in performance vs. comparable 32-bit MCUs in sensorless PMSM control. With an ARM Cortex-M4 core, floating point unit and clock frequencies of up to 150MHz, the Kinetis KV3x and Kinetis KV4x families extend the V series to higher dynamic control systems including those with multiple motors. Kinetis V Series features include dual 16-bit analog-to-digital converters (ADCs) sampling at up to 1.2 mega samples per second (MS/s) in 12-bit mode, multiple motor control timers and 16-512 KB of flash memory. The Kinetis KV4x family includes advanced analog and timing peripherals from Freescale's digital signal controller (DSC) portfolio to address the requirements of digital power conversion applications. All families are supported by a full enablement suite from Freescale and third-party resources, including reference designs, software libraries and motor configuration tools.

Design Resources

Freescale Kinetis V KV1x Microcontrollers are based upon the latest ARM Cortex-M class cores and are designed for a wide range of motor control applications including BLDC, PMSM and ACIM motors. The Kinetis KV1x family is the entry point of the V Series. Built upon the ARM® Cortex®-M0+ core running at 75MHz with hardware square root and divide capability, it delivers a 35% increase in performance in math-intensive applications versus comparable MCUs, allowing it to target BLDC as well as more computationally demanding PMSM motors. Additional features include dual 16-bit analog-to-digital controllers (ADCs) sampling at up to 1.2 mega samples per second (MS/s) in 12-bit mode, multiple motor control timers, up to 32 KB of flash memory and a comprehensive enablement suite from Freescale and third-party resources, including reference designs, software libraries and motor configuration tools.

Features
  • 75MHz Cortex-M0+ core with hardware square root and divide block— improves performance in math-intensive applications (e.g., processing of sensorless field-oriented control (FOC) algorithms)
  • 4-channel DMA — reduced CPU loading for improved application performance
  • 2x 16-bit ADCs with two capture and hold circuits and up to 1.2 MS/s samples rate in 12-bit mode — simultaneous measurement of current and voltage phase, reduced jitter on input values improving system accuracy 12-bit mode
  • 1 x 6-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)
  • 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

  • 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
