Everlight’s “RGB+IC” chip LEDs, sold as 1.8 mm and 3.0 mm chip packages by a major LED maker. Digi-Key lists both as “Addressable Lighting, 1 LED Discrete Serial (Shift Register)”. The sheets carry the part suffix 5V01 and name no IC.

Refresh & flicker

The 12-23C sheet gives absolute maximum supply +3.8 to +5.5 V; the 19-C47 sheet gives +4.2 to +5.5 V and an 800 kbps clock limit. Propagation delay up to 300 ns (12-23C). Colour order is R, G, B, MSB first: the 12-23C data diagram and the application note agree. That is NOT the GRB of the WS2812 family. LED drive current per channel is not stated; luminous intensity is specified at 5 mA.

Both sheets give T0H 300 +/-80, T0L 900 +/-80, T1H 900 +/-80, T1L 300 +/-80 ns and reset above 50 us. The sheets label this “High Speed mode”, implying a second mode, but no other mode is documented.

Clones & compatibility

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

Dating evidence

Evidence, not a release date. A library commit proves the part existed by that date and says nothing about how long before.
