DIGITAL LED WS2812 Upgrade Instructions

Newstime:06-12-18Spring@WorldsemiBrowses:3

Dear Worldsemi's Friends,
 
Thanks so much for your continuous support to our WORLDSEMI digital LED WS2812/WS2813 series. 
 
This is Spring from Worldsemi,We are hereby with pleasure to introduce the lastest major upgrade WS2812 series. 
 
Through the development of new design, the performance will be further optimized, the consistency will be better, and the quality will be greatly improved. 
 
Meanwhile, we will keep upgrading the digital LED WS2813, WS2815 and the Power-line-communication series. 
 
More than anything, the key points of upgrading are as followings:
  1. IC Internal Integrated Filter Capacitor.
  2. Reverse-connection protection.
  3. VCC/DIN/DOUT PIN instantaneously suppresses 12V voltage.
  4. Ensure color consistency even under 3.5V working voltage.
  5. Greatly improved the consistency of the LED's color and brightness LED.
  6. Signal recognition range reduced to less than 2.8V.
  7. Improved EMC/EMI performance.
  8. All upgraded LEDs' defective rate < 1‱.

As there's no change for the mechnical size, timing, electrical&LED characteristics, we do not enable a new part number, only add a suffix version number to distinguish.  
And a continuous flow of the current version LEDs will last for about ONE year. 
 
More details, please check attached file instructions for reference.
 
Should there be anything we can do for you, please feel free to contact with us.
 
Thanks again for your time. Welcome to place sample order for testing first.
Have a nice day!
