Product details
Overview
MKV42F256VLL16 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, two FlexCAN modules, and operates across –40 to 105 °C in industrial motor drives.
For engineers reviewing the MKV42F256VLL16 datasheet, MKV42F256VLL16 pinout, MKV42F256VLL16 application, or MKV42F256VLL16 equivalent, this page delivers verified technical context, validated package mapping (100-pin LQFP), confirmed peripheral configuration (eFlexPWM + dual ADC + FlexCAN), and real-world selection guidance for digital power systems.
Technical Context
The MKV42F256VLL16 implements an Arm Cortex-M4 core with single-precision FPU and runs at up to 168 MHz using a multipurpose clock generator (MCG) with PLL/FLL support. Its analog subsystem includes two independent 12-bit cyclic ADCs (240 ns conversion time) and four analog comparators with integrated 6-bit DACs.
Digital control is enabled by the eFlexPWM module-featuring four submodules delivering 12 PWM outputs with nano-edge timing resolution-and two 8-channel FlexTimers (FTM0/FTM3), one 2-channel FlexTimer (FTM1), and dual FlexCAN 2.0B interfaces supporting CAN FD-ready protocols.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control and digital power conversion applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKV44F256VLL16 | Same core, flash, RAM, and package; adds NanoEdge PWM module and enhanced analog comparator features. | Better suited for ultra-high-resolution sensorless BLDC commutation where 6-bit DAC-assisted comparator thresholds improve startup reliability. | Select MKV44F256VLL16 if NanoEdge timing or comparator-based rotor position estimation is required; otherwise MKV42F256VLL16 offers identical motor control capability at lower cost. |
