A six-pad 5050 pixel with a BIN backup data input and “breakpoint resume”: the sheet says one damaged IC or LED does not affect the data that follows. The sheet does mention DIN and DO as real data pins and, unlike most of the other makers’ sheets here, a backup input. It is the 5050 pad layout and function placement of the WorldSemi WS2813 in this catalogue (DIN, GND, BIN down the left; DO, VDD, NC down the right) but its timing and supply range differ (see the protocol page).

Datasheets disagree: (1) the page-4 outline numbers the pads 1-3-5 on the left and 2-4-6 on the right, with “-” and “+” signs, as for a generic six-pad RGB LED, and puts the cut corner at pin 1 (top-left); the page-6 pin diagram, which is the one that shows the functions, puts the cut corner at the bottom-right next to NC. The pin NUMBERS in this record come from page 4 and therefore depend on whether page 4’s numbering applies to the functional layout - unresolved. (2) The absolute-maximum table says VDD -0.5 to 6.0 V while the working range is 3.7-5.3 V. LCSC stock 3,065.

Outline and pin positions checked against the manufacturer datasheet (C7433062 A-SC5050ARGBC-B01-03-1T V1, p4 (package dimensions, numbered pads) and p6 (pin diagram with functions)). Numbers follow the page-4 outline, which labels the left pads 1, 3, 5 and the right pads 2, 4, 6 from the top; the functions follow the page-6 pin diagram (DIN, GND, BIN down the left; DO, VDD, NC down the right). The sheet's own pin table lists names but no numbers, so the numbering is an inference (see notes). The page-4 drawing puts the cut corner at the top-left; the page-6 pin diagram puts it at the bottom-right, beside NC. The drawing here follows page 6 (where the functions are); this matches the NC pad at the cut corner of the WorldSemi WS2813-5050. What this means.

Compatibility

  • electrically similar WS2813

    Inferred from the sheet's own features and numbers; Amicc never names WorldSemi or WS2813. It has a backup signal input (BIN, "备份信号输入脚") and a breakpoint-resume feature, the pads sit in the same positions as the catalogue's WS2813 5050 (DIN, GND, BIN down the left column; DO, VDD, NC down the right, NC at the cut corner), and its normal-mode figures (T0H 300 ns, reset 280 us, T1H and T0L in a 580 ns to 1 us window) match WorldSemi's newer WS2813 table. T1L, however, is 300 +/-100 ns where the WorldSemi table has 580 ns to 1 us, and colour order is GRB. Supply is 3.7-5.3 V. Not tested. source ↗
