Data Sheet: Technical Data
KV31P100M120SF8
Rev. 5, 4/2015
Kinetis KV31F 256 KB Flash
120 MHz ARM® Cortex®-M4-Based Microcontroller with FPU
The KV31 MCU family is a highly scalable member of the Kinetis
V Series and provides a high-performance, cost-competitive
motor control solution. Built on the ARM®Cortex®-M4 core
running at 120 MHz, combined with floating point and DSP
capability, it delivers a highly capable platform enabling
customers to build a highly scalable solution portfolio.
Additional features include:
• Dual 16-bit ADCs sampling at up to 1.2 MS/s in 12-bit
mode
• 12 channels of highly flexible motor control timers (PWMs)
across 3 independent time bases
• Large RAM block enabling local execution of fast control
loops at full clock speed
