Product details

The NXP MK22FX512VMD12 is an ARM Cortex-M4 MCU clocked at 120 MHz, with 512 KB Flash and 64 KB RAM. It carries 100 I/O lines, a 42-channel 16-bit ADC, dual 12-bit DAC, and serial interfaces including CAN, USB OTG, I²C, SPI, and UART.

120 MHz Cortex-M4 — what it buys you

The 120 MHz core clock puts this MCU in the mid-range performance tier for Cortex-M4 parts. It handles real-time control loops, sensor fusion, and moderate signal processing without an external DSP.

Connectivity and analog front-end

This MCU integrates CAN, USB OTG, and multiple serial buses — enough to serve as a communication bridge in a distributed control system. The 42-channel 16-bit ADC covers high-channel-count analog inputs without external multiplexers; the dual 12-bit DAC handles two analog output channels for setpoint or trim signals.

Frequently asked questions

Is MK22FX512VMD12 obsolete or end-of-life?

The MK22FX512VMD12 is NRND (Not Recommended for New Designs) — it is not yet obsolete, but NXP has flagged it for phase-out. Plan for a last-time-buy window or a migration to an active Kinetis K2x or K6x alternative.

What is the replacement for MK22FX512VMD12?

NXP has not published a direct pin-compatible successor for the MK22FX512VMD12. For new designs, evaluate the active Kinetis K2x series (e.g., MK22FN512VMD12) or the K6x series, which offers similar Cortex-M4 performance with updated peripherals. Check the NXP product migration guide for the latest recommendation.

What is the difference between MK22FX512VMD12 and MK22FN512VMD12?

The MK22FN512VMD12 is the standard Flash variant in the Kinetis K20 family; the MK22FX512VMD12 includes additional FlexMemory (emulated EEPROM) for data retention without external EEPROM. Both share the same 120 MHz Cortex-M4 core, 512 KB Flash, 64 KB RAM, and 144-MAPBGA package. The FX variant is NRND; the FN variant may still be active — verify current lifecycle status before specifying.

What is MK22FX512VMD12's listed speed?

The MK22FX512VMD12 is rated for a 120 MHz core clock on the ARM Cortex-M4 processor.
