Product details

The NXP MK22DN512VLK5 is a 32-bit ARM Cortex-M4 microcontroller running at 50 MHz with 512 KB Flash and 64 KB RAM. It has 56 I/O lines, USB OTG, I²C, SPI, UART, a 20-channel 16-bit ADC, and a 12-bit DAC.

50 MHz Cortex-M4 — what the speed buys you

The 50 MHz ARM Cortex-M4 core includes a single-cycle multiply-accumulate and hardware divide. It does not list FPU in the evidence.

Rated -40 to 105 °C, this part suits industrial environments.

The MK22DN512VLK5 is active in production and ROHS3 compliant. That means no last-time-buy scramble for new designs — you can freeze the BOM line and expect multi-year availability through standard distribution.

Frequently asked questions

What is the core processor of MK22DN512VLK5?

It uses an ARM Cortex-M4 core, 32-bit single-core, running at 50 MHz.

What are the key differences between MK22DN512VLK5 and MK22FN512VLH12?

The MK22DN512VLK5 runs at 50 MHz in an 80-LQFP package, while the MK22FN512VLH12 runs at 120 MHz in a 64-LQFP package. The MK22FN512VLH12 also includes a floating-point unit and more RAM. They are not pin-compatible — the package and pinout differ.

Does MK22DN512VLK5 have a datasheet with electrical specifications?

Yes, the datasheet covers the full electrical specifications, including supply range 1.71 V to 3.6 V, operating temperature -40 to 105 °C, and all peripheral characteristics. Request it with your RFQ.
