Product details
Overview
MKV31F128VLH10 from NXP Semiconductors is a 100 MHz Arm® Cortex®-M4 microcontroller with FPU, 128 KB flash, 16 KB RAM, dual 16-bit ADCs sampling at 1.2 MS/s (12-bit mode), and 46 GPIOs - designed for high-precision motor control in industrial inverters and servo drives.
For engineers reviewing the MKV31F128VLH10 datasheet, MKV31F128VLH10 pinout, MKV31F128VLH10 application, or MKV31F128VLH10 equivalent, this page delivers verified technical context, validated pin assignments for the 64 LQFP package, confirmed motor-control timer architecture, and real-world substitution guidance grounded in NXP's official KV30/KV31 family documentation.
Technical Context
The MKV31F128VLH10 implements a deterministic motor-control subsystem featuring one 6-channel PWM timer and two 2-channel timers with integrated quadrature decoder logic - all synchronized to the 100 MHz Cortex-M4 core. Its analog front end integrates two independent 16-bit SAR ADCs with simultaneous sampling capability and a dedicated 12-bit DAC for closed-loop current/voltage feedback.
System-level timing is managed by a multi-source clock architecture: crystal oscillator support (3–32 MHz), three internal oscillators (32 kHz, 4 MHz, 48 MHz), and a frequency-locked loop (FLL) enabling precise PLL-based system clock generation. Flash access control and hardware CRC ensure firmware integrity in safety-critical motion applications.
