NXP Semiconductors MK20DX256ZVMC10

Overview

MK20DX256ZVMC10 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for embedded control applications requiring real-time signal processing and mixed-signal integration. It operates at up to 100 MHz, integrates 256 KB on-chip flash memory and 128 KB RAM, supports -40°C to +105°C ambient operation, and features dual 16-bit SAR ADCs with integrated PGA, two 12-bit DACs, and USB On-The-Go capability.

For engineers reviewing the MK20DX256ZVMC10 datasheet, MK20DX256ZVMC10 pinout, MK20DX256ZVMC10 application, or MK20DX256ZVMC10 equivalent, key selection considerations include its FlexMemory architecture (256 KB flash + 4 KB FlexRAM), dual CAN interfaces, six UARTs, and support for low-power stop modes down to 2.1 µA in VLLS1 - critical for battery-powered industrial and automotive subsystems.

Technical Context

The MK20DX256ZVMC10 implements an ARM Cortex-M4 core with hardware DSP instructions and a Memory Protection Unit (MPU), enabling deterministic real-time execution in safety-aware systems. Its clock system includes a 3–32 MHz crystal oscillator, 32 kHz RTC oscillator, and multi-purpose clock generator supporting dynamic frequency scaling across power modes.

Peripheral integration centers on mixed-signal control: two independent 16-bit ADCs each with programmable gain amplifier (up to ×64), three analog comparators with internal 6-bit DACs, eight-channel PWM timer, and quadrature decoder timers - all synchronized via a 16-channel DMA controller supporting up to 63 request sources without CPU intervention.

FAQ

What is the maximum operating frequency of the MK20DX256ZVMC10?

The MK20DX256ZVMC10 operates at a maximum CPU frequency of 100 MHz, enabled by its ARM Cortex-M4 core with DSP extensions. This speed is supported across the full voltage range (1.71–3.6 V) and temperature range (-40°C to +105°C), delivering 125 DMIPS and 1.25 Dhrystone MIPS per MHz for deterministic real-time execution in MK20DX256ZVMC10-based systems.

Does the MK20DX256ZVMC10 include hardware cryptographic acceleration?

No, the MK20DX256ZVMC10 does not integrate dedicated cryptographic accelerators such as AES or SHA engines. It includes a hardware CRC module for fast cyclic redundancy checks and a 128-bit unique chip ID, but encryption/decryption operations must be implemented in software. For secure boot or TLS offload, external secure elements or newer Kinetis families (e.g., KE1x) are recommended alternatives to MK20DX256ZVMC10.

What package type and pin count does the MK20DX256ZVMC10 use?

The MK20DX256ZVMC10 uses a 121-pin MAPBGA package (8 mm × 8 mm, 0.5 mm pitch), designated by the 'MC' suffix in its part number. This fine-pitch ball grid array supports high I/O density and thermal performance in compact industrial and automotive PCB layouts, and is compatible with standard reflow profiles for lead-free assembly.

Can the MK20DX256ZVMC10 operate from a single 3.3 V supply?

Yes, the MK20DX256ZVMC10 operates reliably from a single 3.3 V supply within its specified 1.71–3.6 V range. Both VDD and VDDA rails may be tied to 3.3 V (with ≤0.1 V differential), and all I/Os are 5 V tolerant - allowing direct interfacing with legacy 5 V peripherals without level shifters. This simplifies power design in MK20DX256ZVMC10-based applications.

How much FlexRAM does the MK20DX256ZVMC10 provide, and what is its purpose?

The MK20DX256ZVMC10 includes 4 KB of FlexRAM - a user-configurable memory block that can be allocated as additional RAM or emulated EEPROM. Unlike standard RAM, FlexRAM retains data across power cycles when backed by VBAT, enabling nonvolatile parameter storage without external serial EEPROM. This capability is integral to the FlexMemory architecture of MK20DX256ZVMC10 and supports field firmware updates and calibration persistence.
