NXP Semiconductors MK20DX256ZVMD10

Overview

MK20DX256ZVMD10 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, operating at up to 100 MHz, featuring 256 KB on-chip flash memory and 128 KB RAM, integrated dual 16-bit SAR ADCs with PGA, two 12-bit DACs, USB OTG, dual CAN, and six UARTs - deployed in industrial motor control and smart sensor edge nodes.

For engineers reviewing the MK20DX256ZVMD10 datasheet, MK20DX256ZVMD10 pinout, MK20DX256ZVMD10 application, or MK20DX256ZVMD10 equivalent, key selection considerations include its FlexMemory architecture, -40°C to 105°C extended temperature rating, QFN-64 package, 1.71–3.6 V supply range, and support for low-power stop modes down to 2.1 µA.

Technical Context

The MK20DX256ZVMD10 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, paired with a multi-purpose clock generator supporting crystal oscillators (3–32 MHz and 32 kHz), PLL-based frequency synthesis, and dynamic clock gating across subsystems. Its memory subsystem includes 256 KB program flash with FlexNVM capability, 4 KB FlexRAM, and configurable flash security via flash protection blocks.

Peripheral integration centers on deterministic real-time operation: an 8-channel PWM/motor control timer with complementary outputs, two quadrature decoder timers, hardware CRC acceleration, memory protection unit (MPU) with multi-master arbitration, and a 16-channel DMA controller servicing up to 63 request sources - all synchronized to the 100 MHz system clock domain.

FAQ

What is the maximum operating frequency of the MK20DX256ZVMD10?

The MK20DX256ZVMD10 operates at up to 100 MHz using its ARM Cortex-M4 core with DSP extensions. This frequency is achieved via the internal PLL driven by the 3–32 MHz crystal oscillator or internal reference, and is validated across the full -40°C to +105°C temperature range and 1.71–3.6 V supply voltage. The MK20DX256ZVMD10 maintains timing compliance under worst-case voltage and temperature conditions per its published AC electrical specifications.

Does the MK20DX256ZVMD10 support USB device functionality without an external transceiver?

Yes, the MK20DX256ZVMD10 integrates a full-speed USB 2.0 On-The-Go controller with an on-chip transceiver. It supports USB device mode directly using only external series resistors (22 Ω) and ESD protection diodes on USB_DP and USB_DM pins - no external PHY chip is required. This capability is confirmed in the K20 Sub-Family Data Sheet Rev. 7, Section 6.8.1, and applies specifically to the MK20DX256ZVMD10 variant.

What type of memory architecture does the MK20DX256ZVMD10 use?

The MK20DX256ZVMD10 uses FlexMemory architecture, combining 256 KB of program flash memory with 256 KB of FlexNVM (emulated EEPROM) and 4 KB of FlexRAM. Unlike standard flash-only MCUs, this allows runtime partitioning of nonvolatile memory between executable code and wear-leveled data storage - a feature explicitly documented for MK20DX256ZVMD10 in the K20 Sub-Family Data Sheet Section 4.3.2.

What is the lowest power consumption mode supported by the MK20DX256ZVMD10?

The MK20DX256ZVMD10 supports Very Low-Leakage Stop Mode 1 (VLLS1), achieving 2.1 µA typical current draw at 3.0 V and -40°C to 25°C ambient. This mode retains RAM content and selected wakeup sources (LLWU) while disabling the CPU, flash, and most clocks. The value is measured and specified in Table 6 of the K20 Sub-Family Data Sheet Rev. 7, and applies directly to the MK20DX256ZVMD10.

How many analog-to-digital converters does the MK20DX256ZVMD10 integrate?

The MK20DX256ZVMD10 integrates two independent 16-bit successive approximation register (SAR) ADCs, each with up to 16 single-ended or 8 differential input channels and an integrated programmable gain amplifier (PGA) offering gains from 1× to 64×. This dual-ADC configuration is explicitly listed in the "Analog modules" section of the K20 Sub-Family Data Sheet Rev. 7 and confirmed for MK20DX256ZVMD10 in the family summary table.
