For “DMX512 strip”, there are two cases

True DMX512 ICs​ — the pixel itself understands DMX512 / differential DMX and can connect to a DMX console or DMX decoder directly. SPI/TTL pixel ICs​ — WS2811 / SK6812 / UCS1903 etc. are notDMX512 natively; they are controlled via a DMX512 → SPI decoder.

Quick rule for quotations / BOM

  • Say “DMX512 pixel strip”​ → usually means UCS512 / TM512 / SM18522​ family.

  • Say “DMX512 controllable strip”​ → can also mean WS2811/SK6812/UCS1903 + DMX512-SPI decoder.

  • Say “true DMX512 IC”​ → UCS512C4, UCS512H4L, TM512AC, SM18522PS, DMX512B3.
