Product details
Overview
MKV46F128VLH16 from NXP Semiconductors is a 168 MHz Arm Cortex-M4 microcontroller with FPU, designed for high-precision motor control and digital power conversion. It integrates dual 12-bit ADCs (4.1 MSPS), 13-channel eFlexPWM with sub-nanosecond resolution, 64 KB flash, 24 KB RAM, two FlexCAN interfaces, and operates from 1.71–3.6 V across –40 to 105 °C.
For engineers reviewing the MKV46F128VLH16 datasheet, MKV46F128VLH16 pinout, MKV46F128VLH16 application, or MKV46F128VLH16 equivalent, this page delivers verified technical context, validated package mapping, confirmed peripheral capabilities, and real-world motor/power system integration guidance - all grounded in NXP's KV4x Rev. 4 datasheet and official package drawings.
Technical Context
The MKV46F128VLH16 implements an Arm Cortex-M4 core with single-precision FPU and runs at up to 168 MHz using the MCG clock generator with PLL/FLL support. Its analog subsystem includes two independent 12-bit cyclic ADCs (240 ns conversion time), four analog comparators with integrated 6-bit DACs, and one dedicated 12-bit DAC.
Digital control is enabled by the eFlexPWM module (13 PWM channels, 312 ps resolution), three FlexTimer modules (FTM0/FTM1/FTM3 totaling 18 timer channels), two Programmable Delay Blocks (PDB), and Quadrature Encoder interface - all synchronized to a 1:2 timer-to-core clock ratio at full speed.
