Worldsemi WS2812B-4020-V6

WS2812B-4020-V6 is an intelligent externally-controlled LED light source with integrated control circuit and luminescent circuit, where each component constitutes a single pixel. The pixel integrates a smart digital interface data latch, signal reshaping amplification drive circuit, high-precision internal oscillator, and programmable constant current control, effectively ensuring color consistency across pixels. The data protocol uses single-wire return-to-zero (RZ) communication. After power-on reset, the DIN pin receives data from the controller; the first 24 bits of incoming data are extracted by the first pixel and stored in its internal data latch, while the remaining data is reshaped and amplified by the internal signal reshaping circuit, then forwarded through the DO port to the next cascaded pixel — each pixel transmission reduces the signal by 24 bits. The pixel adopts automatic reshaping and forwarding technology, making the cascade count unrestricted by signal transmission limitations and only constrained by signal transmission speed requirements. The port scan frequency reaches up to 2kHz, eliminating flicker even under high-definition camera capture, making it ideal for high-speed moving product applications. A reset time of over 280µs prevents false resets even when interruptions occur, supporting lower-frequency, more cost-effective MCUs. The LED offers the advantages of low-voltage drive, eco-friendly energy efficiency, high brightness, wide scattering angle, excellent consistency, ultra-low power consumption, and ultra-long lifespan. Integrating the control circuit directly into the LED results in a simpler circuit design, smaller footprint, and easier installation.
