MKV31F128VLL10
Overview
The MKV31F128VLL10 is part of NXP's Kinetis KV3x family, specifically designed for high-performance motor control and power conversion applications. It features a 100MHz ARM Cortex-M4 core with a floating-point unit (FPU) and DSP instructions to handle complex control algorithms. This microcontroller balances 128KB of Flash and 24KB of RAM with high-speed analog peripherals including dual 16-bit ADCs.
Why Choose This Part
The integration of a hardware FPU and 100MHz clock speed allows for faster execution of mathematical models compared to standard Cortex-M0+ or M3 devices. It provides superior analog-to-digital conversion with two 16-bit ADCs, enabling simultaneous sampling of phase currents. Additionally, the device offers highly flexible low-power modes, with standby current as low as 1.6uA for energy-sensitive industrial applications.
Applications
Key Specifications
Getting Started
Development is supported by the NXP MCUXpresso SDK, which includes drivers and motor control libraries. For hardware evaluation, the FRDM-KV31F Freedom Development Board is the primary platform for prototyping. Engineers can use MCUXpresso IDE, IAR Embedded Workbench, or Keil MDK along with a standard J-Link or P&E Micro debug probe.
