Dialight 587-1024-147F - 2020 addressable RGB LED, single-wire

587-1024-147F (Dialight) is a self-contained addressable RGB pixel in a 2020 SMD package (2.0 x 2.0 x 0.9 mm, clear epoxy lens): an LED driver IC plus R/G/B emitters with a built-in 20 MHz oscillator, power-on reset and three-channel 5 mA current regulator. One NRZ data line in, one reshaped data line out, 24-bit GRB per pixel. No external capacitor or resistor is required (datasheet p.1).

Pinout (datasheet p.1, mechanical drawing)

Pin Name Function
1 DOUT Serial data out to the next pixel (signal-reshaped)
2 VDD Supply, 3.3-5.5 V (5 V typ)
3 DIN Serial data in, 800 kbps NRZ
4 GND Ground

Pin numbers follow the p.1 mechanical drawing. The p.2 LED schematic carries pin-number typos copied from the 6-pin 587 variant ("GND (PIN 6)" etc.) and was not used.

Not footprint-compatible with the WS2812B-2020. Although the protocol is the same, the pin numbering differs on every pad: on this part VDD is pin 2 and GND is pin 4 (on the WS2812B-2020 they are pins 1 and 3), and DIN/DOUT are pins 3/1 (not 4/2). The land pattern also differs (0.9 x 0.9 mm pads on 1.7 mm pitch here vs 0.7 x 0.5 mm on the adom/ws2812b-2020 footprint). Do not drop this part onto a WS2812B-2020 footprint.

Protocol

Single-wire NRZ at 800 kbps, 24-bit GRB MSB-first per pixel, cascade with per-pixel signal reshaping. Timing: T0H 0.3 us / T0L 0.9 us / T1H 0.9 us / T1L 0.3 us (tolerance +/-0.15 us), reset code low >= 250 us (datasheet p.3). Compatible with WS2812/NeoPixel libraries at the standard 800 kHz timing.

Note on the pad dimensions: the p.1/p.2 dimension callouts are size + gap pairs (0.6 mm terminal with 0.8 mm gap; 0.9 mm pad with 0.8 mm gap), not size + pitch. Verified by pixel measurement of the 600 dpi datasheet render; see provenance/provenance.json.

Footprint

Dialight_587-1024-147F.kicad_mod: 4 SMD pads 0.9 x 0.9 mm at (+/-0.85, +/-0.85) mm (F.Cu + F.Paste + F.Mask), courtyard 3.1 x 3.1 mm, F.Fab body 2.0 x 2.0 mm, silkscreen outline with pin-1 L-bracket at the pad-1 corner. Zero orientation: pad 1 (DOUT) top-left per IPC-7351, which is the datasheet top view rotated 180 degrees.

3D model

587-1024-147f.step / 587-1024-147f.glb are AI-created geometry (no manufacturer CAD exists for this MPN): a beveled 2.0 x 2.0 x 0.9 mm body with the four 0.6 mm terminals, modeled from the datasheet p.1 drawings, Z-up, seated on z = 0, pin-1 terminal aligned with the footprint's pad-1 corner. Generator script: gen/make_step.py (CadQuery 2.8.0).
