Product details
Overview
MK20DN512VLK10R from NXP Semiconductors is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for embedded control applications requiring high integration and low-power operation. It features 512 KB flash, 128 KB RAM, dual 16-bit SAR ADCs with integrated PGA (up to ×64 gain), 12-bit DAC, two CAN 2.0B interfaces, USB OTG, and operates from 1.71–3.6 V across –40 to 105°C ambient.
For engineers reviewing the MK20DN512VLK10R datasheet, MK20DN512VLK10R pinout, MK20DN512VLK10R application, or MK20DN512VLK10R equivalent, key selection considerations include its 100 MHz CPU performance, 80-pin LQFP package with mixed-signal peripheral density, thermal resistance of 9°C/W (junction-to-case), and support for real-time motor control, industrial HMI, and CAN-based gateway functions.
Technical Context
The MK20DN512VLK10R implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, enabling deterministic signal processing in motor control and sensor fusion. Its memory subsystem includes non-FlexMemory flash (512 KB) and 128 KB SRAM, with EzPort serial programming and FlexBus external interface for expansion.
Peripherals are organized into clock-gated domains: dual CAN modules operate independently with dedicated message buffers; two 16-bit ADCs share a common reference but feature separate PGAs and configurable sample rates up to 1 MSPS; the USB OTG controller integrates a full-speed transceiver and supports device/host/OTG modes without external PHY.

FAQ
What is the maximum operating frequency of the MK20DN512VLK10R?
The MK20DN512VLK10R supports a maximum CPU clock frequency of 100 MHz, achieved using the Multipurpose Clock Generator (MCG) in FEI or PBE modes. This frequency is guaranteed across the full –40 to 105°C temperature range and 1.71–3.6 V supply voltage, delivering 1.25 Dhrystone MIPS per MHz for deterministic real-time execution.
Does the MK20DN512VLK10R include hardware security features?
Yes, the MK20DN512VLK10R includes a Memory Protection Unit (MPU) supporting multi-master protection for flash, RAM, and peripherals, plus a hardware CRC module for fast cyclic redundancy checks. It also provides a 128-bit unique identification number per chip, enabling secure device authentication and firmware binding in safety-critical applications.
Can the MK20DN512VLK10R operate from a single 3.3 V supply?
Yes, the MK20DN512VLK10R operates from a single 3.3 V supply within its specified 1.71–3.6 V range. Both VDD and VDDA can be tied to 3.3 V, provided the VDD–VDDA differential remains within ±0.1 V. This simplifies power design for applications without isolated analog domains.
What is the thermal resistance (RθJC) of the MK20DN512VLK10R package?
The MK20DN512VLK10R in its 80-pin LQFP package has a junction-to-case thermal resistance (RθJC) of 9°C/W, as updated in Revision 4 of the K20 Sub-Family Data Sheet (September 2017). This value replaces the prior 8°C/W specification and must be used for thermal modeling and heatsink sizing in high-duty-cycle applications.
How many CAN interfaces does the MK20DN512VLK10R support?
The MK20DN512VLK10R integrates two independent Controller Area Network (CAN) 2.0B modules, each with dedicated message buffers, acceptance filtering, and loopback test mode. Both CAN controllers support bit rates up to 1 Mbps and are fully compatible with ISO 11898-1, enabling dual-network automotive or industrial gateway functionality.
