Worldsemi WS2813-Mini RGB SMD 3535 LED Chip
WS2813-Mini is an intelligent control LED light source that the control circuit and RGB chip are integratedinapackage of 3535 components. Its internal include intelligent digital port data latch and signal reshaping amplificationdrive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant current control part,which achieves highly consistent color effect.
Dual-signal wires version, any pixel’s failure won't affect signal transfer and total emitting effect. The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DINport receivedata from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other datawhichreshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DOport. Aftertransmission for each pixel, the signal to reduce 24bit. Every pixel adopts auto-reshaping transmit technology, makingthe pixel cascade numbers are not limited to the signal transmission, only relate to the speed of signal transmission.
The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis of 24bit data, ifDINdo NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC'sdamagedoes not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after power-off.
Refresh Frequency updates to 2KHz, Low Frame Frequency and no Flicker appear in HD Video Camera.
RESET time>280μs, it won’t cause wrong reset while interruption, it supports the lower frequency andinexpensiveMCU
