The NXP MK20DX256VMC7R is a 32-bit ARM Cortex-M4 MCU clocked at 72 MHz with 256 KB Flash and 64 KB RAM. That Flash footprint holds a moderate firmware image — enough for a fieldbus gateway or motor-control stack with room for a bootloader.
For BOM planning, this means the line is stable through the current product cycle.
The core runs at 72 MHz, which is the headline clock for the ARM Cortex-M4 in this Kinetis K20 variant. That speed handles most real-time control loops and protocol stacks without external clock multiplication.
