Product details
Overview
MK20DN64VFT5 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 OTG, ADC, timers, and communication interfaces. It operates from 1.71–3.6 V across –40 to 105°C and targets industrial control, motor drive, and sensor interface applications requiring deterministic real-time performance.
For engineers reviewing the MK20DN64VFT5 datasheet, MK20DN64VFT5 pinout, MK20DN64VFT5 application, or MK20DN64VFT5 equivalent, key selection considerations include its 48-pin QFN package, FlexMemory absence (N-series), V-range qualification, and USB full-speed OTG capability in a low-power embedded MCU.
Technical Context
The MK20DN64VFT5 implements an ARM Cortex-M4 core with hardware DSP extensions and no FPU (D-suffix). Its clock system includes dual oscillators (3–32 MHz main, 32 kHz RTC), MCG module supporting FEI/FBE/BLPE modes, and configurable bus/system/flash clocks up to 50 MHz.
Peripherals include a 16-bit SAR ADC with 16-channel input multiplexing, two analog comparators with internal 6-bit DACs, eight-channel TPM for PWM/motor control, quadrature decoder, RTC, and USB full-/low-speed OTG controller with on-chip transceiver - all operating within the same 1.71–3.6 V supply domain.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M4 @ 50 MHz with DSP instructions, no FPU - delivers 62.5 DMIPS and supports signal processing in real-time control loops. |
| Flash / RAM | 64 KB program flash, 16 KB SRAM - sufficient for medium-complexity firmware with RTOS and protocol stacks. |
| Voltage Range | 1.71–3.6 V operation - enables direct interface with Li-ion battery systems and industrial 3.3 V rails without level shifting. |
| Temperature Range | –40 to 105°C ambient - qualified for under-hood automotive, industrial drives, and outdoor equipment. |
| USB Interface | Full-/low-speed USB On-The-Go with integrated transceiver - supports device/host roles without external PHY, reducing BOM count. |
| ADC | 16-bit SAR ADC with up to 16 inputs - provides high-resolution analog sensing for precision current/voltage monitoring. |
| Package | 48-pin QFN (7 mm × 7 mm, FT suffix) - compact footprint suitable for space-constrained industrial modules and motor controllers. |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, wettable flank), RoHS-compliant, thermal pad exposed on bottom.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / VSS | Digital power / ground | Primary 1.71–3.6 V supply pair; multiple pins ensure low-impedance distribution and noise immunity. |
| VDDA / VSSA | Analog power / ground | Separate analog domain supply (same voltage range); must be decoupled independently for ADC/CMP accuracy. |
| EXTAL / XTAL | Main crystal oscillator inputs | Accepts 3–32 MHz fundamental-mode crystal; enables precise timing for USB, UART, and real-time control. |
| RTC_CLKIN | 32 kHz RTC oscillator input | Supports external 32.768 kHz crystal for battery-backed real-time clock with ±20 ppm stability. |
| USB_DP / USB_DM | USB differential data lines | Integrated full-speed transceiver; requires 27 Ω series resistors and proper PCB routing per USB 2.0 specifications. |
| PTA0–PTA31, PTB0–PTB15, etc. | GPIO / peripheral multiplexed pins | Up to 42 GPIOs with configurable pull-up/down, slew rate, and drive strength; shared with UART, SPI, I²C, TPM, ADC, CMP. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power operation | Sub-μA stop modes (VLLS0 down to 0.176 μA @ –40 to 25°C) enable battery-powered sensor nodes with multi-year runtime. |
| FlexMemory architecture | Not present (N-suffix); flash-only configuration simplifies memory management but excludes EEPROM-like emulation via FlexNVM. |
| Hardware CRC module | Accelerates checksum computation for firmware updates and communication frame validation, offloading CPU cycles. |
| Programmable delay block | Provides sub-microsecond timing resolution for synchronized sampling, pulse generation, or dead-time insertion in motor control. |
| 128-bit unique ID | Factory-programmed serial number used for secure boot, device authentication, and license binding in production firmware. |
Applications
| Industrial Motor Control | Smart Sensor Node |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK20DX64VFT5 | Includes FlexMemory (64 KB flash + 32 KB FlexNVM + 2 KB FlexRAM); same core, package, and peripherals. | Enables EEPROM emulation and data logging without external memory; higher cost and code complexity for wear leveling. | Select MK20DX64VFT5 only if non-volatile data storage beyond flash programming cycles is required. |
| KEA128MT64xxx | ARM Cortex-M0+, 48 MHz, 128 KB flash, 16 KB RAM, no USB OTG, smaller peripheral set, -40 to 105°C. | Lacks USB, advanced timers, and ADC resolution; suited for cost-sensitive, lower-performance control tasks. | Choose KEA128 for simpler applications where USB and DSP acceleration are unnecessary and BOM cost is critical. |
Compared with MK20DN64VFT5, MK20DX64VFT5 adds FlexMemory at identical pinout and footprint but increases firmware complexity; KEA128MT64xxx reduces feature set and performance to lower cost and power, sacrificing USB and DSP capability for basic control.

What is the maximum operating frequency of the MK20DN64VFT5?
The MK20DN64VFT5 operates at a maximum system and core clock frequency of 50 MHz, as confirmed by its part number suffix '5' and the K20P48M50SF0 datasheet. This frequency is achievable using the internal MCG in FEI or FBE mode with appropriate crystal or external clock source, and supports full-speed USB operation when system clock is ≥20 MHz.
Does the MK20DN64VFT5 include an integrated USB transceiver?
Yes, the MK20DN64VFT5 includes a full-/low-speed USB On-The-Go controller with an integrated transceiver, eliminating the need for an external PHY. The USB_DP and USB_DM pins connect directly to the USB connector with appropriate series termination and ESD protection, as specified in the K20 Sub-Family Data Sheet Rev. 4.
What memory configuration does the MK20DN64VFT5 have?
The MK20DN64VFT5 has 64 KB of program flash memory and 16 KB of SRAM. Its 'N' suffix indicates Flash-only configuration - it does not include FlexMemory (FlexNVM/FlexRAM), distinguishing it from 'X' variants like MK20DX64VFT5 which add 32 KB FlexNVM and 2 KB FlexRAM.
What is the operating temperature range for the MK20DN64VFT5?
The MK20DN64VFT5 is rated for an ambient operating temperature range of –40 to 105°C, indicated by the 'V' in its part number. This qualification makes it suitable for industrial automation, automotive under-hood modules, and outdoor equipment where thermal extremes are expected.
Which package type does the MK20DN64VFT5 use?
The MK20DN64VFT5 uses a 48-pin QFN package (7 mm × 7 mm) with wettable flanks, denoted by the 'FT' in its part number. This RoHS-compliant package features an exposed thermal pad on the bottom for enhanced heat dissipation in thermally constrained designs.
