Product details

It has 512 KB of Flash and 64 KB of RAM, with USB OTG, CAN, SPI, I²C, UART, a 22-channel 16-bit ADC, and a 12-bit DAC.

At 120 MHz, the Cortex-M4 handles a PID loop and USB or CAN traffic. The 64 KB RAM supports moderate data buffers.

Lifecycle status — NRND, plan accordingly

That means NXP is not actively promoting it for new projects, and the long-term supply window is narrowing. For existing production, we source it through independent distribution and quote to order against an RFQ. If you are starting a new design, consider the Kinetis K2x or K6x series as a forward-looking replacement — but verify pin compatibility and peripheral migration before committing the BOM.

Frequently asked questions

What is the core speed of the MK22FX512VLH12?

The ARM Cortex-M4 core runs at 120 MHz, which gives enough throughput for real-time control loops and moderate protocol handling.

What is the closest pin-compatible alternative to the MK22FX512VLH12?

Within the Kinetis K20 family, the MK22FN512VLH12 is a direct Flash-only sibling with the same pinout and package. Verify the exact peripheral set and memory map against your firmware before substituting.
