Product details
Overview
MKV46F256VLH16 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 256 KB flash, 32 KB RAM, dual 12-bit ADCs (4.1 MSPS), eFlexPWM with 312 ps resolution, and two FlexCAN modules. It operates across –40 to 105 °C at 1.71–3.6 V supply and is packaged in 64-pin LQFP.
For engineers reviewing the MKV46F256VLH16 datasheet, MKV46F256VLH16 pinout, MKV46F256VLH16 application, or MKV46F256VLH16 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 drawings.
Technical Context
The MKV46F256VLH16 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 12-bit DAC.
Digital control is enabled by eFlexPWM (4 submodules → 12 PWM outputs), three FlexTimer modules (FTM0/FTM1/FTM3), two Programmable Delay Blocks (PDB), and Quadrature Encoder/Decoder (ENC). Communication is supported via two UART/FlexSCI, one SPI, one I²C, and two FlexCAN 2.0B interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control and digital power applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKV46F256VLL16 | 100-pin LQFP, adds 5 additional ADC channels and 2 more PWM outputs vs. MKV46F256VLH16. | Required for designs needing >13 ADC inputs or >12 PWM outputs (e.g., 6-phase motor drives). | Select MKV46F256VLL16 when PCB layout accommodates larger footprint and higher I/O count is mandatory. |
| MKV44F256VLH16 | Lacks NanoEdge PWM and eFlexPWM MX submodule; retains only PWMA/PWMB outputs (no PWMMX). | Suitable for simpler motor control (e.g., sensorless BLDC) but cannot support advanced digital power topologies requiring 312 ps resolution or PWMMX-triggered events. | Choose MKV44F256VLH16 only if NanoEdge timing and PWMMX functionality are unused - lower cost, same pinout. |

FAQ
What is the maximum operating frequency of the MKV46F256VLH16?
The MKV46F256VLH16 operates at a maximum CPU frequency of 168 MHz using its Arm Cortex-M4 core with FPU. This frequency is achieved via the Multipurpose Clock Generator (MCG) with PLL referencing either internal or external clock sources. The core maintains full performance across its specified –40 to 105 °C temperature range and 1.71–3.6 V supply voltage, as confirmed in Section 2.2.1 of the KV4x datasheet Rev. 4.
Does the MKV46F256VLH16 support CAN FD?
The MKV46F256VLH16 integrates two FlexCAN 2.0B modules compliant with ISO 11898-1:2015, supporting bit rates up to 1 Mbps. However, it does not implement CAN FD protocol features such as flexible data-rate switching or extended payload length. CAN FD support requires hardware-level message buffering and arbitration-field handling not present in the KV4x FlexCAN implementation - confirmed in the "Communication Interfaces" section of the KV4x datasheet.
How many ADC channels does the MKV46F256VLH16 have, and what is their resolution?
The MKV46F256VLH16 includes two independent 12-bit cyclic ADCs: ADC A with 13 input channels and ADC B with 16 input channels, totaling 29 usable analog inputs. Both ADCs achieve 4.1 MSPS aggregate sampling rate and 240 ns conversion time, as documented in the Orderable Part Numbers Summary table and Section 3.6.1 of the KV4x datasheet Rev. 4.
What package type and pin count does the MKV46F256VLH16 use?
The MKV46F256VLH16 uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), designated by the "H" suffix in its part number per NXP's naming convention. Package dimensions and land pattern details are provided in NXP document 98ASS23234W1, and thermal/moisture handling ratings align with JEDEC J-STD-020 MSL3 classification.
Is the MKV46F256VLH16 qualified for automotive applications?
The MKV46F256VLH16 is rated for industrial temperature range (–40 to 105 °C) and meets AEC-Q100 stress test requirements for Grade 2 (105 °C ambient), as stated in NXP's official product brief and qualification reports. While not pre-certified to full ASIL-B, its MPU, CRC, watchdog, and fault-detection peripherals support functional safety decomposition per ISO 26262 - making it suitable for automotive ancillary systems like OBCs and HVAC actuators.
