Overview

The MK20DX256VLH7 is an ARM Cortex-M4 based microcontroller from the NXP Kinetis K20 family, operating at up to 72MHz. It features 256KB of Flash memory, a dedicated USB 2.0 full-speed On-The-Go (OTG) controller, and an integrated hardware touch sensing interface (TSI).

Why Choose This Part

This MCU provides a hardware Floating Point Unit (FPU) and DSP instructions, enabling faster mathematical processing for sensor fusion and audio tasks. Its flexible low-power modes, reaching as low as 1.1uA in standby, make it highly efficient for portable embedded systems.

Applications

USB Peripheral Devices
The integrated USB controller and transceiver make it ideal for creating custom HID, MIDI, or CDC serial devices.
Human-Machine Interfaces
Utilizes the 16-channel hardware touch sensing interface for capacitive touch buttons and sliders without high CPU overhead.
Consumer Electronics
Well-suited for battery-powered devices requiring low-power sleep modes and efficient DSP performance via the Cortex-M4 core.
Industrial Control
Leverages the hardware CRC module and 16-channel DMA for reliable data processing and high-speed peripheral communication.
