Product details
Overview
MK20DN128VLH5 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 core microcontroller with DSP extensions, designed for embedded control applications requiring real-time signal processing and low-power operation. It integrates 128 KB on-chip flash, 16 KB RAM, 16-bit SAR ADC, USB OTG controller, and operates at up to 50 MHz across –40°C to +105°C ambient temperature.
For engineers reviewing the MK20DN128VLH5 datasheet, MK20DN128VLH5 pinout, MK20DN128VLH5 application, or MK20DN128VLH5 equivalent, key selection considerations include its FlexMemory-free configuration (flash-only), LQFP-64 package, industrial temperature grade, and support for multiple low-power modes including VLLS0 with POR detect enabled.
Technical Context
The MK20DN128VLH5 implements an ARM Cortex-M4 core with hardware DSP instructions and no FPU, operating at up to 50 MHz via internal MCG clock generator supporting FEI, FBE, and BLPE modes. Its memory subsystem includes 128 KB program flash, 16 KB SRAM, and no FlexNVM/FlexRAM - confirmed by the 'N' in the part number denoting flash-only configuration.
Peripherals include a full-speed USB OTG controller with on-chip transceiver, three UARTs, two I²C modules, SPI, I²S, eight-channel TPM/PWM timer, RTC, and dual analog comparators with integrated 6-bit DACs. All analog and digital I/O operate within 1.71–3.6 V supply range, with dedicated VDDA/VSSA pins and ±0.1 V differential tolerance between VDD and VDDA.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK20DX128VLH5 | Includes FlexMemory (64 KB FlexNVM + 2 KB FlexRAM); same core, peripherals, and package | Required where runtime EEPROM emulation or data logging to nonvolatile storage is needed | Select MK20DX128VLH5 only if FlexNVM usage is confirmed; otherwise MK20DN128VLH5 offers lower cost and identical performance for flash-only use cases |
| K22FN128VLH5 | ARM Cortex-M4F (with FPU), higher max frequency (120 MHz), enhanced USB stack, and larger debug ROM | Suitable for floating-point intensive tasks (e.g., audio codecs, advanced filtering) and faster USB bulk transfers | K22FN128VLH5 is not pin-compatible; requires PCB redesign but provides future-proofing for compute-heavy upgrades |
Compared with MK20DN128VLH5, MK20DX128VLH5 adds FlexMemory at identical pinout and footprint, while K22FN128VLH5 upgrades core capability and speed but mandates layout changes - making MK20DN128VLH5 optimal for cost-sensitive, flash-only industrial control deployments.

FAQ
What does the 'N' in MK20DN128VLH5 signify?
The 'N' in MK20DN128VLH5 indicates a flash-only memory configuration - meaning the device contains 128 KB of program flash and 16 KB of RAM, but no FlexNVM or FlexRAM. This distinguishes it from the 'X' variant (e.g., MK20DX128VLH5), which includes FlexMemory for EEPROM emulation. The MK20DN128VLH5 is optimized for applications where firmware storage is the sole nonvolatile requirement.
Does MK20DN128VLH5 support USB device mode without an external PHY?
Yes, MK20DN128VLH5 integrates a full-speed USB On-The-Go controller with an on-chip transceiver, enabling direct connection to USB hosts or peripherals without an external PHY. The USB_DP and USB_DM pins are routed internally to the transceiver, requiring only standard series termination (27 Ω) and a 1.5 kΩ pull-up on DP for full-speed enumeration - simplifying design and reducing bill-of-materials cost.
What is the lowest achievable current consumption in stop mode for MK20DN128VLH5?
In Very Low-Leakage Stop Mode 0 (VLLS0) with POR detect circuit disabled, MK20DN128VLH5 achieves as low as 0.176 µA at –40°C to 25°C ambient temperature. This ultra-low leakage enables years of operation on coin-cell batteries in wake-on-event applications such as security sensors or environmental monitors, provided all clocks and peripherals are gated and RAM retention is not required.
Can MK20DN128VLH5 operate reliably at 1.8 V supply voltage?
Yes, MK20DN128VLH5 is fully specified to operate across 1.71 V to 3.6 V, including 1.8 V nominal supply. At 1.8 V, it supports up to 25 MHz system clock (per device clock specifications), maintains full peripheral functionality, and meets all electrical behaviors including ADC accuracy and I/O drive strength - making it suitable for dual-supply systems or low-voltage battery-powered designs.
Is MK20DN128VLH5 pin-compatible with other K20 family members in the LH package?
Yes, MK20DN128VLH5 shares identical pinout and package (64-pin LQFP, 10 mm × 10 mm) with other K20 devices ending in 'LH5', including MK20DX128VLH5, MK20DN64VLH5, and MK20DX64VLH5. This allows drop-in replacement within the same memory size tier and enables hardware reuse across product variants - though firmware compatibility must be verified due to differences in FlexMemory presence and peripheral enablement.
