120 MHz 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
• 20 channels of highly flexible motor control timers (PWMs)
across 4 independent time bases
• Large RAM block enabling local execution of fast control
loops at full clock speed

Performance
• 120 MHz ARM Cortex-M4 core with DSP instructions
delivering 1.25 Dhrystone MIPS per MHz
Memories and memory interfaces
• 512 KB of embedded flash and 96 KB of RAM
• FlexBus external bus interface
• Serial programming interface (EzPort)
• Preprogrammed Kinetis flashloader for one-time, insystem factory programming
System peripherals
• Flexible low-power modes, multiple wake-up sources
• 16-channel DMA controller
• Independent external and software watchdog monitor
Clocks
• One crystal oscillator with two ranges: 32-40 kHz or
3-32 MHz
• Three internal oscillators: 32 kHz, 4 MHz, and 48 MHz
• Multipurpose clock generator with PLL and FLL
Security and integrity modules
• Hardware CRC module
• 128-bit unique identification (ID) number per chip
• Hardware random-number generator
• Flash access control to protect proprietary software
