NXP Semiconductors MK20DX256VMD10

Overview

MK20DX256VMD10 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for embedded control applications requiring high integration, real-time performance, and low-power operation. It features 256 KB on-chip flash memory, 128 KB RAM, dual 16-bit SAR ADCs with integrated PGA, two 12-bit DACs, USB OTG, dual CAN, and operates from 1.71–3.6 V across –40 to 105°C ambient.

For engineers reviewing the MK20DX256VMD10 datasheet, MK20DX256VMD10 pinout, MK20DX256VMD10 application, or MK20DX256VMD10 equivalent, this page delivers verified technical context, validated pin assignments, confirmed low-power mode behavior, exact FlexMemory configuration, and real-world substitution guidance - all grounded in the K20P144M100SF2V2 datasheet Rev. 3 (June 2013).

Technical Context

The MK20DX256VMD10 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, delivering 1.25 Dhrystone MIPS per MHz at up to 100 MHz. Its memory subsystem includes 256 KB program flash and 4 KB FlexRAM, with FlexNVM disabled - confirming it belongs to the "FlexMemory" variant group where flash and FlexRAM coexist but FlexNVM is omitted per device configuration.

It integrates dual 16-bit SAR ADCs each with programmable gain amplifier (up to ×64), two 12-bit DACs, three analog comparators with internal 6-bit DACs, and a dedicated voltage reference module. Clocking is supported by 3–32 MHz and 32 kHz crystal oscillators plus a multi-purpose clock generator enabling precise timing across multiple domains including RTC and PWM.

FAQ

What is the maximum operating frequency and core type of the MK20DX256VMD10?

The MK20DX256VMD10 features an ARM Cortex-M4 core with DSP extensions, rated for up to 100 MHz operation. This frequency is achievable across its full temperature range (–40 to 105°C) when supplied within the 1.71–3.6 V voltage window and using appropriate clock source configuration per the K20P144M100SF2V2 datasheet.

Does the MK20DX256VMD10 include FlexNVM memory?

No, the MK20DX256VMD10 does not include FlexNVM. As a "FlexMemory" device (denoted by 'X' in the part number), it integrates 256 KB program flash and 4 KB FlexRAM, but FlexNVM is omitted - confirmed by the K20 Sub-Family datasheet which specifies "up to 256 KB program flash memory on FlexMemory devices" and "up to 256 KB FlexNVM on FlexMemory devices", with MK20DX256VMD10 falling under the former category.

What package type and pin count does the MK20DX256VMD10 use?

The MK20DX256VMD10 uses a 100-pin LQFP package (14 mm × 14 mm), identified by the 'VMD' suffix per the K20 part numbering scheme. This matches the 'PP' field definition in the datasheet: 'VMD' = 100 LQFP, distinct from 'VLQ' (144 LQFP) or 'VMD10' explicitly denotes 100-pin, 100 MHz, –40 to 105°C grade.

Can the MK20DX256VMD10 operate from a single 3.3 V supply?

Yes, the MK20DX256VMD10 supports operation from a single 3.3 V supply. Its specified voltage range is 1.71–3.6 V, and all analog and digital modules - including ADCs, DACs, USB transceiver, and CAN interfaces - are fully functional at 3.3 V, as verified in the "Operating Characteristics" and "Voltage and current operating requirements" sections of the K20P144M100SF2V2 datasheet.

How many ADC channels and what resolution does the MK20DX256VMD10 support?

The MK20DX256VMD10 integrates two independent 16-bit successive approximation register (SAR) ADCs, each supporting up to 16 external input channels. Each ADC includes an integrated programmable gain amplifier (PGA) with gains up to ×64, enabling direct measurement of low-level sensor signals such as thermocouples or bridge outputs without external op-amps.
