NXP Semiconductors MK20DX64VMP5

Overview

MK20DX64VMP5 from NXP Semiconductors (formerly Freescale) is a 50 MHz ARM Cortex-M4 microcontroller with DSP extension, 64 KB program flash, 16 KB RAM, and FlexMemory architecture supporting configurable 2 KB FlexRAM and optional 32 KB FlexNVM. It operates from 1.71–3.6 V across –40 to 105°C and integrates USB OTG, 16-bit ADC, dual comparators with 6-bit DACs, and eight-channel PWM timer - deployed in industrial motor control and smart sensor edge nodes.

For engineers reviewing the MK20DX64VMP5 datasheet, MK20DX64VMP5 pinout, MK20DX64VMP5 application, or MK20DX64VMP5 equivalent, key selection criteria include its 64-pin MAPBGA package, -40°C to +105°C extended temperature rating, FlexMemory configurability for data logging, USB full-speed OTG capability with on-chip transceiver, and low-power stop modes down to 0.176 µA (VLLS0, POR disabled).

Technical Context

The MK20DX64VMP5 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, delivering 1.25 Dhrystone MIPS per MHz at up to 50 MHz. Its clock system includes a 3–32 MHz crystal oscillator, 32 kHz RTC oscillator, and multi-purpose clock generator with MCG supporting FEI, FBE, and BLPE modes.

Peripherals are organized around a 4-channel DMA controller servicing 41 request sources, a programmable delay block, real-time clock with calendar, carrier modulator transmitter, and communication interfaces including three UARTs, two SPI modules, I²C, I²S, and USB full-/low-speed On-The-Go with integrated transceiver and voltage regulator.

FAQ

What is the maximum operating frequency of the MK20DX64VMP5?

The MK20DX64VMP5 operates at a maximum core/system clock frequency of 50 MHz. This is achieved using the internal MCG clock generator in FEI or FBE mode with an external crystal, and is validated across the full –40°C to +105°C temperature range and 1.71–3.6 V supply. The MK20DX64VMP5 does not support frequencies above 50 MHz, even with external clock sources.

Does the MK20DX64VMP5 include USB functionality, and what type?

Yes, the MK20DX64VMP5 integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver and internal 3.3 V regulator. It supports device, host, and OTG roles without requiring external PHY components. The MK20DX64VMP5 USB module complies with USB 2.0 specification and includes dedicated endpoints, buffers, and descriptors for rapid enumeration.

What memory configuration options does the MK20DX64VMP5 FlexMemory support?

The MK20DX64VMP5 FlexMemory supports runtime reconfiguration between 2 KB FlexRAM and up to 32 KB FlexNVM. FlexRAM functions as fast, nonvolatile RAM with EEPROM-like endurance; FlexNVM emulates EEPROM using flash blocks with built-in wear leveling. This configuration is managed via FTFL command set and persists across resets - a capability unique to the MK20DX64VMP5 within its pin-compatible family.

What is the lowest power consumption mode supported by the MK20DX64VMP5?

The MK20DX64VMP5 achieves its lowest active power state in Very-Low-Leakage Stop Mode 0 (VLLS0), drawing as little as 0.176 µA at 3.0 V and –40°C when the POR detect circuit is disabled. In this mode, the RTC remains functional using VBAT, and wake-up can occur via GPIO, RTC alarm, or LLWU inputs - making the MK20DX64VMP5 suitable for decade-scale battery operation in sensor endpoints.

Is the MK20DX64VMP5 pin-compatible with other K20 family members?

Yes, the MK20DX64VMP5 is pin-compatible with other 64-pin MAPBGA K20 devices sharing the "VMP5" suffix, including MK20DN64VMP5, MK20DX128VMP5, and MK20DN128VMP5. Pin assignments, power domains, and peripheral multiplexing are identical across these variants; only flash size, FlexMemory presence, and core attributes (D vs. N) differ - enabling seamless migration without PCB changes.
