Product details

NRND — plan your procurement window

That means NXP is not actively promoting it for fresh projects, though it remains available for existing production runs through the independent channel. If you are qualifying a new BOM, look at the Kinetis K2x or K6x families for a current-generation Cortex-M4 alternative.

Industrial temperature grade and connectivity

What the 100 MHz core and 256 KB Flash mean for your design

At 100 MHz, the Cortex-M4 handles real-time control loops. The 256 KB Flash and 64 KB RAM support a mid-complexity firmware image.

Frequently asked questions

Is MK20DX256ZVLL10 obsolete?

The MK20DX256ZVLL10 is classified as NRND (Not Recommended for New Designs) by NXP. It is not fully discontinued, but NXP advises against using it in new projects. For existing production, we can source it to order — submit an RFQ for current availability and pricing.

What is the replacement for MK20DX256ZVLL10?

NXP has not published a direct pin-compatible replacement for the MK20DX256ZVLL10. For new designs, consider the Kinetis K2x or K6x series (e.g., MK20DX256VLL10 or MK64FN1M0VLL12) which offer similar or higher Flash/RAM in the same 100-LQFP package. Verify pin compatibility against your schematic before switching.

What is MK20DX256ZVLL10's listed speed?

The MK20DX256ZVLL10 is rated for a 100 MHz core speed on the ARM Cortex-M4 processor.

What is the pinout of MK20DX256ZVLL10?

The MK20DX256ZVLL10 comes in a 100-LQFP package with 66 general-purpose I/O pins. The full pinout is documented in the NXP K20 Sub-Family Reference Manual and datasheet — we recommend downloading the PDF from NXP's site for signal assignments and alternate functions.
