Pixel Protocol Overview: CS8812

This pixel protocol was designed by Witop Technology Co. Ltd in China. It uses 12V as its main power input for each chip, VDD, which is then dropped down to 5V inside each pixel for its logic requirements. This allows longer chains of pixels to driven in series. The control circuit comes in two physical format options: SOP8 and SMD5050. In the 5050 SMD package, LEDs are integrated, which provides a small physical footprint for each pixel. In the SOP8 package, LEDs are external to the control circuit, allowing for more flexibility with LED choice.

CS8812 Advantages

  • Very high PWM rate allows for filming these pixels with cameras up to 267fps
  • 12V operation allows for long cable lengths and long chains of pixels
  • Redundant data line reduces chance of entire strip failure
  • 12-bit built-in gamma correction makes dimming curves more smooth
  • Option for either SOP8 or SMD5050

CS8812 Disadvantages

  • Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
