      APA104 LED CHIP

Features and Benefits

Intelligent reverse connect protection, the power supply reverse connection does not damage the IC.

The control circuit and the LED share the only power source.

Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point.

Built-in signal reshaping circuitafter wave reshaping to the next driver, ensure wave-form distortion not accumulate.

Built-in electric reset circuit and power lost reset circuit.

Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and 

       scan frequency not less than 400Hz/s.

Cascading port transmission signal by single line.

Any two point the distance more than 5m transmission signal without any increase circuit.

When the refresh rate is 30fps, cascade number are not less than1024 points.

Send data at speeds of 800Kbps.

General description

APA104 is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit.Also include a precision internal oscillator and a 12V voltage programmable constant current control part, effectively ensuring the pixel point light color height consistent.-nt control part, effectively ensuring the pixel point light color height consistent.The data transfer protocol use single NZR communication mode. After the pixel powern reset, the DIN  port receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade  pixel through the DO port. After transmission for each  pixel,the signal to reduce 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number is not limited the signal transmission, only depend on the speed of signal transmiss
