Pixel Protocol Overview: TM1809

This pixel protocol was designed by Titan Micro Electronics in China. TM1809 is equipped with all the same features as its previous version, TM1803, but supports 3 RGB pixels off the one chip. The control circuit comes in a SOP14 package, allowing for more flexibility with LED choice.

TM1809 Advantages

  • Up to 24V, allowing for very long cable lengths
  • Drives 3 pixels off a single SOP14 chip.

TM1809 Disadvantages

  • Low PWM rate makes theses pixels unsuitable for cameras
  • Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
  • Only 8 bits of data for each color makes dimming curves less smooth
  • No redundancy in data
