Product details
Overview
MK20DX32VFT5 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 core microcontroller with DSP instructions, 32 KB program flash, 16 KB RAM, and FlexMemory architecture supporting configurable EEPROM-like storage. It operates from 1.71–3.6 V across –40 to 105°C and integrates USB OTG, multiple UARTs, I²C, SPI, I²S, 16-bit ADC, analog comparators, and real-time clock - deployed in industrial sensor nodes and motor control edge devices.
For engineers reviewing the MK20DX32VFT5 datasheet, MK20DX32VFT5 pinout, MK20DX32VFT5 application, or MK20DX32VFT5 equivalent, this page delivers verified electrical specs, package mapping to 48-pin QFN (7 mm × 7 mm), low-power mode timing behavior, USB transceiver compliance, and validated alternative part comparisons - all grounded in K20P48M50SF0 Rev. 4 (May 2012) technical data.
Technical Context
The MK20DX32VFT5 implements an ARM Cortex-M4 core with hardware DSP extensions and no FPU, running at up to 50 MHz with 1.25 Dhrystone MIPS/MHz. Its memory subsystem includes 32 KB on-chip flash, 16 KB SRAM, and FlexMemory enabling 2 KB FlexRAM + up to 32 KB FlexNVM for EEPROM emulation.
Clocking uses dual oscillators: 3–32 MHz main crystal and 32 kHz RTC crystal, managed by the Multi-Purpose Clock Generator (MCG) supporting FEI, FBE, BLPE, and PBE modes. System-level peripherals include 4-channel DMA, low-leakage wakeup unit, hardware CRC, and 128-bit unique chip ID.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| K22F512VLH12 | ARM Cortex-M4F (with FPU), 512 KB flash, 120 MHz max, 100-pin LQFP; lacks FlexMemory but adds Ethernet MAC and SDHC. | Better suited for complex protocol stacks (TCP/IP, FATFS) and floating-point math; not drop-in due to larger package and different peripheral mapping. | Select when floating-point computation or Ethernet connectivity is required; rework PCB layout and middleware stack. |
| MKE15Z64VLD4 | ARM Cortex-M0+, 64 KB flash, 48 MHz, 48-pin QFN; no USB OTG, no FlexMemory, lower power (1.71–3.6 V), -40 to 105°C. | Targeted at cost-sensitive, low-complexity control tasks; lacks DSP acceleration and USB device capability. | Choose for simpler deterministic control where USB and DSP are unnecessary; retains same footprint but requires firmware porting. |
Compared with MK20DX32VFT5, K22F512VLH12 offers higher performance and connectivity at the cost of board redesign, while MKE15Z64VLD4 provides pin-compatible simplicity without USB or FlexMemory - making MK20DX32VFT5 optimal for balanced USB-enabled, EEPROM-emulating edge controllers.

FAQ
What is the maximum operating frequency of the MK20DX32VFT5?
The MK20DX32VFT5 supports a maximum system and core clock frequency of 50 MHz, as specified in the K20P48M50SF0 datasheet Rev. 4. This frequency is achievable across the full –40°C to +105°C ambient temperature range when supplied with 1.71–3.6 V and using the MCG in appropriate modes (e.g., FBE or PBE). The MK20DX32VFT5 does not support frequencies above 50 MHz.
Does the MK20DX32VFT5 include an integrated USB transceiver?
Yes, the MK20DX32VFT5 integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver. This eliminates the need for an external USB PHY and supports both host and device roles. Electrical compliance is verified per USB 2.0 specifications, with VDD = 3.3 V and fSYS = 48 MHz conditions confirmed in the K20P48M50SF0 Rev. 4 test data.
What memory types are available on the MK20DX32VFT5?
The MK20DX32VFT5 includes 32 KB of program flash, 16 KB of SRAM, and FlexMemory architecture comprising 2 KB of FlexRAM and up to 32 KB of FlexNVM. The FlexNVM can be configured as emulated EEPROM or additional program flash, enabling field-upgradable nonvolatile data storage without external components - a key feature distinguishing the 'X' variant from 'N' variants like MK20DN32VFT5.
What is the operating temperature range for the MK20DX32VFT5?
The MK20DX32VFT5 is rated for operation from –40°C to +105°C ambient temperature, as indicated by the 'V' suffix in its part number (MK20DX32VFT5). This extended temperature grade is validated per JEDEC JESD22-A104 and supports deployment in under-hood automotive modules, industrial drives, and outdoor sensor enclosures without derating.
Is the MK20DX32VFT5 pin-compatible with other K20 family members?
The MK20DX32VFT5 uses a 48-pin QFN (FT) package and shares identical pinout with other K20 devices in the same package option - including MK20DN32VFT5, MK20DX64VFT5, and MK20DN64VFT5 - as documented in Section 8.2 "K20 Pinouts" of K20P48M50SF0 Rev. 4. However, peripheral enablement and memory mapping differ; firmware must be adapted for flash/RAM size and FlexMemory presence.
