Product details

Kinetis K20 MCU — 120 MHz Cortex-M4 with 512 KB Flash

The NXP MK22FX512VLL12 is a 32-bit ARM Cortex-M4 microcontroller clocked at 120 MHz with 512 KB of Flash and 64 KB of RAM. It integrates CAN, USB OTG, EBI/EMI, I²C, SPI, and DMA.

What the 120 MHz core and 512 KB Flash mean for your BOM

At 120 MHz, the Cortex-M4 handles single-loop motor control or CAN-based sensor fusion. The 512 KB Flash holds a full application stack.

Connectivity and analog features

The part includes a CAN controller, USB OTG with on-chip PHY, and an external bus interface that can connect to parallel LCDs or external SRAM. DMA offloads peripheral-to-memory transfers without CPU intervention, which matters for high-data-rate USB or SPI traffic.

Frequently asked questions

Is MK22FX512VLL12 obsolete?

No, it is NRND (Not Recommended for New Designs), not yet obsolete. NXP has signaled end-of-life planning, but the part remains available through independent distribution for existing production. Sourced to order against an RFQ.

What are the key differences between MK22FX512VLL12 and MK22FN512VLL12?

The MK22FX512VLL12 is NRND; the MK22FN512VLL12 is active. Both are pin-compatible with identical core, memory, and peripheral sets — the difference is lifecycle status only.
