World Semi

  • WS stands for World Semi (their site might be down, or is this the wrong link?)
  • Variants are:
    • WS2801 - Older protocol? 4 pin version (unlike other WS) that requires a data and clock input
    • WS2803 - Older 18 Channel (28 pin) PWM LED Driver Chip (LEDs not included)
    • WS2811 - Generally refers to the chip that is not integrated with the actual LEDs aka it's usually an 8-Pin SOIC (Small Outline Integrated Circuit) that takes Data withOUT a clock signal and controls 3 LEDs (Typically Red Green and Blue) and then passes along the data signal minus those first 3 values.
    • WS2812 - The original (?) integrated LED and driver chip package aka it's a 5050 sized SMD (5mm by 5mm) square that has not only a miniaturized WS2811, but also connected Red, Green and Blue LEDs fit into said 5050 package. Takes in ~5VDC and data, outputs data minus first 3 values to the next chip.
    • WS2812b - Newer updated version of WS2812
    • WS2813 - Newer updated version of WS2812b with backup data line capabilities allowing pass-through data should one chip die (two in a row dying is still a problem)
    • WS2815 - 12VDC native chip with backup data line capability (similar to WS2813)
    • WS2815A - Uses a WS2819 IC? 5050 size surface mount
    • WS2818 - Same idea as WS2813 but in SOIC, DIP or MSOP 8pin format like the WS2811. aka not integrated with LED.
      • WS2818A - 5V
      • WS2818B - 12V
      • WS2818C - 24V
    • WS2821
    • WS2832
    • WS2836???

APA Electronics

Made by APA Electronics Inc.?

  • APA102 - clock line required - older, square lens (also comes in smaller 3535 SMD and newer smaller 2020 SMD)
  • APA102c - updated version of APA102 (aka still requires clock) - round lens similar to shape of WS2812
  • APA104 - no clock - same protocol as ws2812?
  • APA109 - APA chip integrated into RGBW 5050 SMD - Warm, Neutral, and Cool White versions?
