Product details

120 MHz Cortex-M4 with 512 KB Flash — what it buys you on the BOM

The NXP MK20FX512VMD12 is an ARM Cortex-M4 MCU running at 120 MHz, with 512 KB Flash, 128 KB RAM, and 16 KB EEPROM on-chip.

Connectivity and peripheral set for industrial control

The EBI/EMI is the key differentiator here — it lets you hang an external parallel SRAM, NOR Flash, or a display controller directly off the bus, which the smaller Kinetis K-series parts lack. DMA, I²S, LVD, POR, PWM, and WDT round out the peripheral set, so a single MK20FX512VMD12 can handle sensor fusion, PWM motor drive, and audio playback without a companion CPLD or codec.

Frequently asked questions

What is MK20FX512VMD12's listed speed?

The ARM Cortex-M4 core runs at 120 MHz, which puts it in the mid-to-upper tier of the Kinetis K20 family for throughput.

What compliance documentation does NXP provide for MK20FX512VMD12?

The part is ROHS3 compliant. NXP provides a declaration of compliance; no UL or IEC certification is listed in the standard documentation for this MCU.
