Kinetis KV1x Microcontrollers NXP Semiconductors Kinetis KV1x Microcontrollers (MCU) are based upon the Arm® Cortex®-M0+ class cores and are the entry point of the Kinetis V series. This Cortex-M0+ core runs at 75MHz with hardware square root and divide capability and delivers a 35% increase in performance in math-intensive applications. NXP KV1x MCUs also feature dual 16-bit Analog-to-Digital Controllers (ADC), multiple motor control timers, and up to 32KB of flash memory.
