Product details

The NXP MK20DX64VFM5 is a 32-bit ARM Cortex-M4 microcontroller from the Kinetis K20 family, clocked at 50 MHz with 64 KB Flash and 16 KB RAM. Typical applications include industrial control nodes, sensor hubs, portable instrumentation, and USB-enabled embedded systems where a balance of performance, peripheral integration, and small footprint is required.

The 16 KB RAM is the tighter resource — firmware that relies on large buffers or multiple protocol stacks may need to manage memory carefully.
