Product details
Overview
MK20DN32VFT5 from NXP Semiconductors (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 delivers 1.25 Dhrystone MIPS/MHz at up to 50 MHz, integrates 32 KB program flash, 16 KB RAM, and operates across –40°C to 105°C in a 48-pin QFN package. It is used in industrial sensor nodes and motor control interfaces where deterministic timing and analog integration are critical.
For engineers reviewing the MK20DN32VFT5 datasheet, MK20DN32VFT5 pinout, MK20DN32VFT5 application, or MK20DN32VFT5 equivalent, this page provides verified technical context, validated pin functions, confirmed low-power mode behavior, exact flash/RAM partitioning, and two rigorously cross-referenced alternative parts - all derived from the K20P48M50SF0 datasheet Rev. 4 (May 2012) and official NXP ordering documentation.
Technical Context
The MK20DN32VFT5 implements an ARM Cortex-M4 core with hardware DSP instructions and no FPU (indicated by 'D' in part number), supporting single-cycle MAC and saturating arithmetic. Its clock system includes a multi-purpose clock generator (MCG) with internal reference, 3–32 MHz crystal oscillator, and 32 kHz RTC oscillator - enabling precise timekeeping and flexible frequency synthesis.
It features integrated analog peripherals including a 16-bit SAR ADC, two analog comparators with 6-bit DACs and programmable references, and voltage reference module. Communication is supported via USB full-/low-speed OTG, three UARTs, SPI, I²C, and I²S - all with configurable pin multiplexing and DMA-assisted operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M4 with DSP, no FPU - enables efficient fixed-point signal processing without floating-point overhead. |
| Max Clock Frequency | 50 MHz - supports real-time control loops with sub-20 ns instruction cycle time. |
| Flash Memory | 32 KB program flash only ('N' in part number) - no FlexNVM; sufficient for compact firmware with bootloader and safety checks. |
| RAM | 16 KB SRAM - accommodates stack, heap, and real-time buffers for sensor fusion or motor commutation. |
| Operating Voltage | 1.71 V to 3.6 V - compatible with single-cell Li-ion, 3.3 V logic rails, and battery-backed operation. |
| Temperature Range | –40°C to +105°C - qualified for under-hood automotive and industrial ambient environments. |
| ADC Resolution | 16-bit SAR - provides high-resolution analog sensing for precision current/voltage monitoring. |
| USB Interface | Full-/low-speed On-The-Go controller with on-chip transceiver - eliminates external PHY for host/peripheral reconfiguration. |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), identified by 'FT' in part number per K20P48M50SF0 Section 2.3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Digital power supply and ground | Must be decoupled locally; VDD supports 1.71–3.6 V operation with ≤0.1 V differential to VDDA. |
| VDDA, VSSA | Analog power supply and ground | Independent analog rail; requires separate filtering to maintain 16-bit ADC accuracy. |
| EXTAL/XTAL | Primary crystal oscillator input/output | Supports 3–32 MHz crystals; essential for USB clock derivation and high-accuracy timing. |
| RTC_CLKIN | 32 kHz RTC oscillator input | Enables battery-backed real-time clock operation independent of main system power. |
| USB_DP/USB_DM | USB differential data lines | Integrated transceiver eliminates external PHY; requires 27 Ω series resistors and proper PCB routing. |
| PTA0–PTA31, PTB0–PTB15, etc. | GPIO with multiplexed peripheral functions | Each port pin supports up to 8 alternate functions (e.g., UART0_TX, ADC0_SE0, CMP0_OUT); configured via SIM_SOPT2 and PORTx_PCRn registers. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power modes (VLLS0–VLLS3, LLS, VLPS) | Sub-μA stop-mode currents (as low as 0.176 μA at –40°C to 25°C with POR disabled) enable battery life extension in always-on sensor nodes. |
| Hardware CRC module | Accelerates checksum computation for firmware integrity verification and communication frame validation without CPU load. |
| 8-channel PWM timer with motor control support | Enables 3-phase BLDC commutation with dead-time insertion and fault protection inputs - no external timer IC required. |
| Programmable delay block (PDB) | Synchronizes ADC sampling, PWM updates, and DAC outputs with sub-microsecond precision for closed-loop control. |
| 128-bit unique chip ID | Provides immutable device identity for secure boot, license binding, and field firmware authentication. |
| FlexMemory architecture (not present) | This variant (MK20DN32VFT5) has program flash only - excludes FlexNVM/FlexRAM; use MK20DX variants for EEPROM emulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK20DX32VFT5 | Same core, package, and memory size, but includes FlexMemory (32 KB FlexNVM + 2 KB FlexRAM) for EEPROM emulation. | Required when field-upgradable parameter storage or wear-leveling data logging is needed. | Select MK20DX32VFT5 if nonvolatile data retention beyond flash endurance limits is mandatory. |
| MK20DN64VFT5 | Same architecture and package, but doubles flash to 64 KB and RAM to 16 KB (same RAM size) - no FlexMemory. | Suitable for larger firmware images with RTOS, OTA update capability, or expanded peripheral stacks. | Choose MK20DN64VFT5 when 32 KB flash is insufficient for application + bootloader + safety monitors. |

FAQ
What is the maximum operating frequency of the MK20DN32VFT5?
The MK20DN32VFT5 operates at up to 50 MHz, as confirmed in the K20P48M50SF0 datasheet Section 5.3.1. This frequency applies to both system and core clocks in normal run mode, with flash clock limited to 25 MHz. The '5' in the part number suffix explicitly denotes 50 MHz capability.
Does the MK20DN32VFT5 include FlexMemory (FlexNVM/FlexRAM)?
No, the MK20DN32VFT5 does not include FlexMemory. Per the K20P48M50SF0 datasheet and part number decoding (Section 2.3), the 'N' in MK20DN32VFT5 indicates program flash only. FlexMemory is present only in 'X' variants like MK20DX32VFT5.

Which USB speed modes does the MK20DN32VFT5 support?
The MK20DN32VFT5 supports both full-speed (12 Mbps) and low-speed (1.5 Mbps) USB operation via its integrated On-The-Go controller, as stated in the K20P48M50SF0 datasheet Features section. No external PHY is required due to the on-chip transceiver.
How much RAM is available on the MK20DN32VFT5?
The MK20DN32VFT5 includes 16 KB of general-purpose SRAM, as documented in the K20P48M50SF0 datasheet Features section and consistent across all '32'-sized K20 devices regardless of flash type (N or X).
