A 12 V driver IC with a backup data line, closely related to the WS2815. Seeded for completeness of the family; no single-package part yet.

Clones & compatibility
“Compatible” is never stated bare here — each relationship carries how strong the claim is, and what bites if you assume too much.

Both are 12 V parts with a backup line; the bit periods differ (1200 ns vs 1890 ns), so they are not interchangeable without changing timings.

Parts using this protocol
No package is catalogued for this protocol yet — it is seeded for family completeness, or it is a driver IC that drives external LEDs rather than shipping as an integrated package.
Dating evidence
Evidence, not a release date. A library commit proves the part existed by that date and says nothing about how long before.
