NRND — plan a replacement now
That means NXP has flagged it for eventual phase-out — no last-time-buy date is published here, but the clock is running on fresh factory allocation. For a production BOM that already uses this code, the immediate concern is securing a bridge supply while qualifying a replacement. The Kinetis K20 family has several pin-compatible siblings that share the 100-LQFP footprint and peripheral map; a cross-reference search against the base product number MK20DN512 will surface the active alternatives. For new designs, do not spec this part — pick a current Kinetis K-series device that NXP still actively supports.
100 MHz Cortex-M4 — what the speed buys you
The 33-channel 16-bit ADC and single 12-bit DAC cover analog front-end tasks like current sensing and setpoint generation on the same die.
Connectivity and I/O
USB OTG support is confirmed — this MCU can act as either a USB host or device, which matters for designs that need to connect to a flash drive for data logging or to a tablet for configuration. The CANbus controller suits it for automotive aftermarket and industrial fieldbus nodes. The EBI/EMI interface allows glueless connection to external SRAM or NOR Flash if the on-chip 512 KB is not enough.
Sourcing posture
Because this part is NRND, the standard authorized-distributor channel may already be winding down allocation. If you need a long-term dual-source solution, we can also help qualify a pin-compatible active Kinetis K-series alternate — the base MK20DN512 footprint is shared across several speed and memory options.
