Worldsemi WS2812B-2020-V6

WS2812B-2020-V6 is an intelligent externally-controlled LED light source with integrated control and light-emitting circuits. Utilizing the latest molding encapsulation process, the IC and light-emitting chip are packaged within a 2020-size package, with each component serving as a single pixel. Each pixel integrates a smart digital interface with data latch, signal reshaping amplification driver circuit, high-precision internal oscillator, and programmable constant-current control, ensuring high consistency in light color. The data protocol uses single-wire return-to-zero communication. After power-on reset, each pixel receives controller data via the DIN pin. The first pixel extracts the initial 24 bits of data, while the remaining data is reshaped, amplified, and forwarded to the next cascaded pixel via the DO pin — each pixel reduces the signal by 24 bits. The automatic reshaping and forwarding technology enables unlimited cascade count, constrained only by signal transmission speed requirements. The port scan frequency reaches up to 2KHz, with no flickering under high-definition camera capture, making it suitable for high-speed motion product applications. The RESET time is greater than 280μs, preventing false resets from interrupts and enabling support for lower-frequency, more cost-effective MCUs. The LED offers the advantages of low-voltage drive, environmental friendliness and energy efficiency, high brightness, wide scattering angle, excellent consistency, ultra-low power consumption, and an exceptionally long lifespan. Integrating the control circuit directly into the LED simplifies the overall circuit, reduces form factor, and eases installation.
