Overview

The MK20DX256VLK10 is a high-performance Kinetis K20 series microcontroller featuring an ARM Cortex-M4 core running at up to 100MHz. It integrates 256KB of Flash memory, 128KB of RAM, and a dedicated 4KB EEPROM for non-volatile data storage, making it suitable for applications requiring complex communication and reliable data logging.

Why Choose This Part

This MCU offers a robust mix of connectivity options including USB OTG and CAN, alongside a hardware DSP-capable core for efficient signal processing. Its low-power architecture achieves 8.5mA at 48MHz in run mode and features multiple deep-sleep modes down to 137uA for battery-sensitive applications.

Applications

Industrial Communications Bridge
Utilizing integrated CANbus and USB OTG for protocol conversion between industrial fieldbuses and host computers.
High-Fidelity Audio Processing
Leveraging the I2S interface and Cortex-M4 DSP instructions for real-time digital audio stream handling.
Secure Data Loggers
Using the 4KB EEPROM for persistent configuration storage and the SDHC interface for high-capacity external storage.
USB-to-Serial Gateways
Implementing high-speed USB-to-UART or USB-to-SPI bridges in professional instrumentation.
