Datasheets disagree

The sources we hold state different values for the facts below. Rather than pick one quietly, both sides are listed with where each was read. Check the datasheet for the exact part number and revision you are buying. How this is shown.

Package drawing

The WS2812S sheet puts its chamfer in two different corners.

ws2812s-c114584 dimension view: C0.8 chamfer at top-left 2
ws2812s-c114584 pin diagram: chamfer at pin 1 (bottom-right) 2

What we show. Drawn from the pin diagram, with pin 1 at the chamfer. Check the polarity mark on the part itself.

A six-pin 5050 with separate supply pins for the control circuit (VCC) and the LEDs (VDD), plus a no-connect - the same pin structure the catalogue describes for the original WS2812. The sheet does not say it is the original WS2812 silicon, so it is catalogued on its own. Unlike the four-pin parts its T1L window is 220-420 ns.

Outline and pin positions checked against the manufacturer datasheet (C114584 WS2812S sheet p2). The sheet is inconsistent: its dimension view puts the C0.8 chamfer top-left, its pin diagram puts it at pin 1 (bottom-right). Drawn from the pin diagram. What this means.

Compatibility

  • electrically similar WS2812

    Both are six-pin 5050 parts with separate control (VCC) and LED (VDD) supply pins and a no-connect. The WS2812S sheet does not say it is the original WS2812 silicon, and its timing windows differ from the original sheet's 350/800/700/600 ns +/-150 ns.

Dating evidence

Nobody announces these parts, so this records what we can actually cite rather than a release date. Library support proves only that the part existed by that date.
