NXP Semiconductors MK20DX32VMP5

Overview

MK20DX32VMP5 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extension, designed for embedded control applications requiring real-time signal processing and low-power operation. It features 32 KB program flash, 16 KB RAM, 16-bit SAR ADC, USB full-/low-speed On-The-Go controller, and operates from 1.71–3.6 V at –40 to 105°C ambient temperature.

For engineers reviewing the MK20DX32VMP5 datasheet, MK20DX32VMP5 pinout, MK20DX32VMP5 application, or MK20DX32VMP5 equivalent, this page delivers verified technical context, validated package mapping, confirmed peripheral capabilities, and real-world design implications - all tied explicitly to the MK20DX32VMP5 variant in the K20 sub-family.

Technical Context

The MK20DX32VMP5 implements an ARM Cortex-M4 core with DSP instructions, delivering 1.25 Dhrystone MIPS per MHz at up to 50 MHz. Its memory subsystem includes 32 KB on-chip flash, 16 KB SRAM, and FlexMemory architecture enabling configurable FlexNVM/FlexRAM partitions - though this specific part has no FlexNVM (X = FlexMemory-capable, but 32 KB flash indicates base configuration).

It integrates a multi-purpose clock generator supporting 3–32 MHz crystal oscillator and 32 kHz RTC crystal, eight-channel PWM timer, two quadrature decoder timers, real-time clock, and communication interfaces including USB OTG, three UARTs, SPI, I²C, and I²S - all operating within the same voltage and thermal envelope (1.71–3.6 V, –40 to 105°C).

FAQ

What is the maximum operating frequency of the MK20DX32VMP5?

The MK20DX32VMP5 operates at a maximum core/system clock frequency of 50 MHz, as confirmed by its "CC=5" field in the part number and validated in the K20 Sub-Family Data Sheet Rev. 4. This frequency is achievable across the full –40 to 105°C temperature range when supplied with 1.71–3.6 V, and enables deterministic real-time execution for motor control and sensor processing tasks. The MK20DX32VMP5 maintains this rating without derating under specified thermal and voltage conditions.

Does the MK20DX32VMP5 include a hardware floating-point unit (FPU)?

No, the MK20DX32VMP5 does not include a hardware FPU. Its part number decodes as "D" (Cortex-M4 with DSP) but not "F" (Cortex-M4 with DSP + FPU). All floating-point operations must be handled in software or via CMSIS-DSP library functions optimized for the M4's integer and SIMD capabilities. This design choice reduces silicon area and power consumption while retaining strong fixed-point signal processing performance - consistent with the MK20DX32VMP5's target use cases in motor control and sensor aggregation.

What package type does the MK20DX32VMP5 use, and is it RoHS compliant?

The MK20DX32VMP5 uses a 64-pin MAPBGA package (5 mm × 5 mm, 0.5 mm pitch), indicated by the "MP" suffix in its part number. It is lead-free and RoHS compliant, with moisture sensitivity level (MSL) 3 per J-STD-020 - requiring bake conditioning if exposed beyond floor life. The package supports automated assembly with standard reflow profiles and provides high I/O density in a compact footprint ideal for space-constrained industrial and portable designs.

Can the MK20DX32VMP5 operate from a single 3.3 V supply across all peripherals?

Yes, the MK20DX32VMP5 supports single-supply operation at 3.3 V for both digital (VDD) and analog (VDDA) domains, within the specified 1.71–3.6 V range. Its ADC, USB transceiver, and I/O pins are fully functional at 3.3 V, and the internal voltage regulator for USB (VREGIN) accepts up to 6.0 V - allowing direct connection to 3.3 V system rails without external regulators. This simplifies power design in applications such as USB-connected sensor nodes and portable instrumentation where board space and BOM count are critical.

How does the FlexMemory feature manifest in the MK20DX32VMP5 compared to MK20DN32VMP5?

The "X" in MK20DX32VMP5 explicitly denotes FlexMemory capability - meaning the device contains dedicated FlexNVM and FlexRAM blocks that can be configured as EEPROM-emulated storage or additional program flash. In contrast, MK20DN32VMP5 ("N" = no FlexMemory) lacks these blocks entirely. While the MK20DX32VMP5's 32 KB flash allocation leaves no spare FlexNVM in default configuration, the hardware support enables runtime partitioning - a key differentiator for applications requiring field-upgradable calibration data or secure firmware rollback mechanisms.
