Built upon the Cortex-M0+ core running at 75 MHz with hardware square root and divide capability, Kinetis KV1x microcontrollers deliver a 27% increase in performance in math-intensive applications versus comparable MCUs, allowing them to target BLDC as well as more computationally demanding PMSM motors. Additional features include integrated FlexCAN, dual 16-bit analogto-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 128 KB of flash memory and a comprehensive enablement suite both from us and thirdparty resources, including reference designs, software libraries and motor configuration tools.
- 75 MHz Cortex-M0+ core with hardware square root and divide block that improves performance in math-intensive applications (e.g., processing of sensorless fieldoriented control (FOC) algorithms)
- 2 x 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
- Up to 2 x 6-channel and 4 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 ACMP (analog comparators) for overcurrent and overvoltage fault detection and reduced BOM costs; ADC and ACMP interconnect with PWM and PDB (programmable delay) blocks for real-time hardware control
- 4-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
