NXP Semiconductors MKV44F64VLH16

Overview

MKV44F64VLH16 from NXP Semiconductors is a 168 MHz Arm Cortex-M4 microcontroller with FPU, designed for motor control and digital power conversion. It integrates dual 12-bit ADCs (240 ns conversion), 13-channel ADC A, 16-channel eFlexPWM with 312 ps resolution, 64 KB flash, 16 KB RAM, and two FlexCAN modules. It operates from 1.71–3.6 V across –40 to 105 °C in a 64-pin LQFP package.

For engineers reviewing the MKV44F64VLH16 datasheet, MKV44F64VLH16 pinout, MKV44F64VLH16 application, or MKV44F64VLH16 equivalent, this page delivers verified technical context, validated pin functions, confirmed motor-control timing specs, real-world analog interface constraints, and cross-referenced alternatives for industrial drive and SMPS firmware development.

Technical Context

The MKV44F64VLH16 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 (4.1 MSPS), four analog comparators with integrated 6-bit DACs, and one 12-bit DAC - all supported by programmable reference inputs and PDB-triggered sampling.

Digital control is enabled by the eFlexPWM module (4 submodules → 12 PWM outputs), two 8-channel FlexTimers (FTM0/FTM3), one 2-channel FlexTimer (FTM1), quadrature encoder support, and dual FlexCAN 2.0B interfaces. The 64LQFP package provides dedicated high-drive GPIO pins (PTB0/1, PTC3/4, PTD4–7) and true open-drain outputs (PTC6/7).

FAQ

What is the maximum ADC sampling rate supported by MKV44F64VLH16?

The MKV44F64VLH16 supports up to 4.1 MSPS aggregate sampling rate across its dual 12-bit cyclic ADCs, with individual channel conversion time of 240 ns. This enables simultaneous sampling of up to 13 analog inputs (ADC A) and 7 inputs (ADC B) per conversion cycle - critical for three-phase current reconstruction in motor control applications. MKV44F64VLH16 achieves this performance with hardware PDB synchronization and no CPU intervention.

Does MKV44F64VLH16 support CAN FD or only classical CAN?

MKV44F64VLH16 integrates two FlexCAN 2.0B modules supporting only Classical CAN (ISO 11898-1, up to 1 Mbps), not CAN FD. It lacks the extended data length and bit-rate switching capabilities required for CAN FD. For CAN FD applications, designers must select newer NXP S32K or i.MX RT families. MKV44F64VLH16 remains fully compatible with existing industrial CAN networks and automotive diagnostic protocols relying on Classical CAN.

What is the minimum supply voltage required for MKV44F64VLH16 to operate its ADC and nano-edge PWM modules?

MKV44F64VLH16 requires a minimum 2.7 V on VDDA for ADC operation and 3.0 V on both VDD and VDDA for nano-edge PWM functionality. Below 2.7 V, ADC accuracy degrades beyond specification; below 3.0 V, nano-edge features are disabled. These thresholds are enforced by internal voltage monitors - MKV44F64VLH16 will assert LVD reset if either rail falls outside its respective operating window during runtime.

Can MKV44F64VLH16 run code directly from RAM, and what is the impact on real-time performance?

Yes, MKV44F64VLH16 supports executing code from its 16 KB SRAM, reducing instruction fetch latency by eliminating flash wait states. When running from RAM at 168 MHz, interrupt response time improves by ~120 ns versus flash execution, and deterministic loop timing becomes less sensitive to cache misses. However, RAM execution consumes more power and reduces available buffer space - MKV44F64VLH16 firmware typically reserves RAM for critical control loops while keeping non-real-time tasks in flash.

How many independent PWM carrier frequencies can MKV44F64VLH16 generate simultaneously?

MKV44F64VLH16 can generate up to four independent PWM carrier frequencies simultaneously using its eFlexPWM module's four submodules (PWMA, PWMB, PWMX, and NanoEdge). Each submodule has its own clock prescaler and counter, allowing distinct frequencies (e.g., 20 kHz for motor control, 500 kHz for auxiliary DC-DC, 1 MHz for gate driver bias supply) without CPU scheduling overhead. MKV44F64VLH16 maintains phase alignment between carriers via shared PDB triggers.
