Product details
Overview
MKV42F256VLL16R 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), eFlexPWM with 312 ps resolution, 256 KB flash, 32 KB RAM, and two FlexCAN modules. It operates across –40 to 105 °C at 1.71–3.6 V supply and is packaged in 100-pin LQFP.
For engineers reviewing the MKV42F256VLL16R datasheet, MKV42F256VLL16R pinout, MKV42F256VLL16R application, or MKV42F256VLL16R equivalent, this page delivers verified technical context, validated pin functions, real-world motor/power use cases, and two confirmed alternative parts - all grounded in NXP's KV4x Rev. 4 datasheet and official package documentation.
Technical Context
The MKV42F256VLL16R implements an Arm Cortex-M4 core with single-precision FPU and runs at up to 168 MHz using MCG with PLL/FLL clock generation. Its analog subsystem includes two independent 12-bit cyclic ADCs (240 ns conversion time) and four analog comparators each with integrated 6-bit DAC and programmable reference.
Digital control is enabled by eFlexPWM with four sub-modules delivering 12 PWM outputs, plus three FlexTimer modules (FTM0/FTM1/FTM3) supporting encoder interface, periodic interrupts, and programmable delay blocks. It lacks NanoEdge PWM hardware - confirmed by orderable part summary table where "Nano-Edge" column shows "-" for all MKV42Fxxx variants.
