NXP Semiconductors MKV42F128VLH16

Overview

MKV42F128VLH16 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, 240 ns conversion), 13-channel eFlexPWM with sub-nanosecond resolution, 128 KB flash, 24 KB RAM, and two FlexCAN modules - deployed in industrial servo drives and switched-mode power supplies.

For engineers reviewing the MKV42F128VLH16 datasheet, MKV42F128VLH16 pinout, MKV42F128VLH16 application, or MKV42F128VLH16 equivalent, this page delivers verified electrical specs, validated package mapping (64-pin LQFP), confirmed peripheral configurations (eFlexPWM + dual ADC + FlexCAN), and real-world motor/power use cases - all extracted from NXP's official KV4x Data Sheet Rev. 4 (09/2019).

Technical Context

The MKV42F128VLH16 implements an Arm Cortex-M4 core with single-precision FPU and operates at up to 168 MHz using MCG with PLL/FLL clock generation. Its analog subsystem includes two independent 12-bit cyclic ADCs (each with 18/13-channel input multiplexing), four analog comparators with integrated 6-bit DACs, and one 12-bit DAC - all supported by programmable delay blocks (PDB) for synchronized sampling.

Digital control is enabled via eFlexPWM with four submodules delivering 12 PWM outputs, plus three FlexTimer modules (FTM0/FTM1/FTM3) supporting encoder interface (ENC), quadrature decoding, and nano-edge timing. Communication is handled by two FlexCAN 2.0B modules, two UART/FlexSCI interfaces, one SPI, and one I²C - all operating within 1.71–3.6 V supply and –40 to 105 °C industrial temperature range.

FAQ

What is the maximum operating frequency of the MKV42F128VLH16 core?

The MKV42F128VLH16 features an Arm Cortex-M4 core rated for up to 168 MHz operation, confirmed in the NXP KV4x Data Sheet Rev. 4 (Section 1.1). This frequency is achievable using the MCG's PLL mode with an external 4–32 MHz crystal or oscillator source, and is validated across the full –40 to 105 °C temperature range and 1.71–3.6 V supply.

Does the MKV42F128VLH16 include hardware floating-point support?

Yes, the MKV42F128VLH16 integrates a single-precision Floating Point Unit (FPU) as part of its Arm Cortex-M4 core, enabling efficient execution of trigonometric, logarithmic, and matrix operations required in field-oriented control (FOC) and digital power loop calculations - a key differentiator from Cortex-M0+/M3 variants.

How many ADC channels does the MKV42F128VLH16 support, and what is their resolution?

The MKV42F128VLH16 includes two independent 12-bit cyclic ADC modules: ADC0 supports up to 18 input channels, and ADC1 supports up to 13 channels. Both achieve 4.1 MSPS aggregate throughput and 240 ns conversion time, as specified in Table 3.6.1 of the KV4x Data Sheet Rev. 4.

What communication interfaces are integrated into the MKV42F128VLH16?

The MKV42F128VLH16 integrates two FlexCAN 2.0B modules, two UART/FlexSCI interfaces, one SPI module, and one I²C module. All are fully functional in the 64-pin LQFP package and operate across the full industrial temperature and voltage range - enabling CAN-based motor networks, debug serial links, and sensor/I/O expansion buses.

Is the MKV42F128VLH16 pin-compatible with other KV4x family members in the same package?

Yes, the MKV42F128VLH16 shares identical 64-pin LQFP pinout with MKV42F256VLH16, MKV44F128VLH16, and MKV46F128VLH16 - confirmed by NXP's package drawings (98ASS23234W1) and signal multiplexing tables. Peripheral register mapping and default pin functions remain consistent across these variants, enabling drop-in firmware reuse.
