Product details
Overview
MKV42F256VLH16P from NXP is a high-performance ARM Cortex-M4 microcontroller optimized for motor and power control, featuring 168 MHz operation, 256 KB flash/32 KB SRAM, dual 12-bit ADCs (4.1 MSPS), 16-channel eFlexPWM with up to 312 ps resolution, and dual FlexCAN interfaces. It targets BLDC, PMSM, and AC induction motor drives in industrial inverters and photovoltaic systems.
For engineers reviewing the MKV42F256VLH16P datasheet, MKV42F256VLH16P pinout, MKV42F256VLH16P application, or MKV42F256VLH16P equivalent, key selection criteria include PWM channel count, ADC sampling rate, CAN interface support, FlexTimer configuration flexibility, and LQFP-64 package compatibility with space-constrained motor control PCBs.
Technical Context
The MKV42F256VLH16P implements an ARM Cortex-M4 core with DSP extension and single-precision FPU, enabling real-time execution of sensorless field-oriented control (FOC) algorithms. Its memory subsystem includes a 128-bit wide flash interface with cache to minimize wait states during fast control loop execution.
Peripherals are architected for deterministic timing: dual 12-bit ADCs with programmable gain amplifiers support synchronized sampling across multiple motor phases; eFlexPWM and FlexTimers provide hardware-accelerated PWM generation with sub-nanosecond resolution and integrated encoder decoding or power factor correction logic.

FAQ
What is the maximum operating frequency of the MKV42F256VLH16P?
The MKV42F256VLH16P operates at a maximum core frequency of 168 MHz using its ARM Cortex-M4 processor with DSP extension and single-precision floating-point unit. This frequency is achieved via internal PLL synthesis from an external 4–24 MHz crystal, and it is fully supported across the full industrial temperature range (–40°C to +105°C). All peripherals, including ADCs and PWM modules, are clocked synchronously to maintain timing integrity at this speed.
Does the MKV42F256VLH16P include hardware-based PWM fault protection?
Yes, the MKV42F256VLH16P supports hardware fault protection through its FlexTimer modules and GPIO fault inputs. While it does not include the eFlexPWM module (present in MKV44 variants), its FlexTimers provide configurable fault sources, blanking windows, and automatic PWM shutdown with configurable recovery modes - enabling safe torque off (STO) compliance per IEC 61800-5-2 when properly configured in the application firmware.
How many analog-to-digital converter channels does the MKV42F256VLH16P support?
The MKV42F256VLH16P integrates two independent 12-bit ADCs (ADCA and ADCB) with a total of 13 input channels. These ADCs support simultaneous sampling, programmable gain amplifiers (PGAs), and hardware-triggered conversions synchronized to PWM events - delivering up to 4.1 mega samples per second aggregate throughput for high-fidelity current and voltage sensing in motor control loops.
Is the MKV42F256VLH16P pin-compatible with other Kinetis KV4x MCUs in LQFP-64 packages?
Yes, the MKV42F256VLH16P shares the same LQFP-64 mechanical footprint and basic signal mapping with MKV44F256VLH16 and MKV46F256VLH16, but functional pin assignments differ across variants - especially for PWM, ADC, and FlexTimer signals. Engineers must verify peripheral signal routing against the specific variant's pin multiplexing table; direct replacement without firmware and layout review is not guaranteed.
What development tools are officially supported for the MKV42F256VLH16P?
The MKV42F256VLH16P is fully supported by NXP's MCUXpresso Software and Tools suite, including MCUXpresso IDE, SDK, and Config Tools. It is also compatible with Kinetis Design Studio, IAR Embedded Workbench for ARM, and Keil MDK. Hardware evaluation is enabled via Tower System modules like TWR-KV46F168M (with adapter) and HVP-MC3PH, both validated for KV4x motor control firmware targeting MKV42F256VLH16P.
