Product details
Overview
MK20DN64VLH5 from NXP Semiconductors (formerly Freescale) is a 50 MHz ARM Cortex-M4 core microcontroller with DSP instructions, 64 KB program flash, 16 KB RAM, and integrated USB full-/low-speed On-the-Go controller. It operates from 1.71–3.6 V across –40 to 105°C and targets industrial motor control and embedded HMI applications requiring real-time analog acquisition and low-power operation.
For engineers reviewing the MK20DN64VLH5 datasheet, MK20DN64VLH5 pinout, MK20DN64VLH5 application, or MK20DN64VLH5 equivalent, key selection criteria include its 64 LQFP package, FlexMemory absence (N-suffix), 16-bit SAR ADC with dual comparators, eight-channel PWM timer, and support for VLPS/VLLS low-power stop modes with sub-μA current draw.
Technical Context
The MK20DN64VLH5 implements a multi-clock architecture with MCG supporting FEI/FBI/FBE/BLPE modes, enabling dynamic clock scaling between 50 MHz run mode and 4 MHz VLPR mode. Its system-level integration includes a 4-channel DMA controller servicing up to 41 request sources and hardware CRC acceleration for firmware integrity verification.
Analog subsystem design centers on a 16-bit SAR ADC with configurable sample time and conversion triggers, two analog comparators each with 6-bit DAC and programmable reference inputs, and independent voltage reference module - all operating within the same 1.71–3.6 V supply range as digital domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK20DX64VLH5 | Includes FlexMemory (64 KB flash + 32 KB FlexNVM + 2 KB FlexRAM); identical core, package, and peripherals | Required when EEPROM-like nonvolatile data storage or emulated EEPROM functionality is needed | Select MK20DX64VLH5 only if runtime reconfigurable data storage is essential; otherwise MK20DN64VLH5 offers lower cost and simpler memory management |
| K22FN512VLH12 | ARM Cortex-M4F (FPU enabled), 120 MHz, 512 KB flash, 128 KB RAM, same 64 LQFP package | Suitable for computationally intensive tasks like floating-point filter banks or real-time FFT analysis | Choose K22FN512VLH12 when floating-point math performance or larger memory footprint justifies migration; not drop-in compatible due to different register mapping and peripheral revisions |
Compared with MK20DX64VLH5, MK20DN64VLH5 eliminates FlexMemory overhead for simpler deterministic flash writes; versus K22FN512VLH12, it trades raw compute throughput for lower power consumption and proven qualification in extended temperature industrial environments.

FAQ
What is the maximum operating frequency of the MK20DN64VLH5?
The MK20DN64VLH5 operates at a maximum system and core clock frequency of 50 MHz, as confirmed by the '5' suffix in its part number and validated in K20P64M50SF0 Rev. 4 Table 9. This frequency is achievable using the MCG in FEI or FBE modes with appropriate crystal or external clock source, and is supported across the full –40 to 105°C temperature range.
Does the MK20DN64VLH5 include FlexMemory?
No, the MK20DN64VLH5 does not include FlexMemory. The 'N' in its part number explicitly denotes program flash only, distinguishing it from 'X' variants like MK20DX64VLH5 which integrate FlexNVM and FlexRAM. All 64 KB of nonvolatile storage is executable program flash, with no emulated EEPROM or data flash capability.
What USB capabilities does the MK20DN64VLH5 support?
The MK20DN64VLH5 integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver, supporting device, host, and OTG roles without external PHY components. It complies with USB 2.0 specification and requires only a 1.5 kΩ pull-up resistor on USB_DP for full-speed enumeration, as documented in K20P64M50SF0 Section 6.8.1.
How many analog-to-digital converter channels does the MK20DN64VLH5 have?
The MK20DN64VLH5 features a single 16-bit SAR ADC module with up to 16 external input channels (ADC0_SE0–ADC0_SE15), configurable for single-ended or differential acquisition. Channel count is determined by pin multiplexing - not all 16 pins are available simultaneously in the 64 LQFP package, but the ADC hardware supports the full set per K20P64M50SF0 Section 6.6.1.
What low-power modes are available on the MK20DN64VLH5?
The MK20DN64VLH5 supports seven low-power modes: RUN, WAIT, VLPR, VLPS, STOP, LLS, and VLLS0–VLLS3. Measured currents range from 509 μA in VLPR mode to 0.176 μA in VLLS0 with POR disabled, all verified at 3.0 V and –40°C per K20P64M50SF0 Table 6. Wakeup sources include GPIO, RTC alarm, and LPTMR timeout.
