APA102C datasheet led


APA102 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 3 groups shift register and Selfdetection sign decoder circuit. Also include a 4.5V voltage regulator part and continuous oscillator effectively ensuring the pixel point light color height consistent.
The data transfer protocol use two-line decoder mode. After the pixel power-on reset, the DIN port receive data from controller after decoder, the first pixel collect initial 24bit data then sent to the internal data register, the other data which reshaping by the internal signal decoder circuit sent to the next cascade pixel through the DO CO port. After transmission for each pixel. LED with low driving voltage, environmental protection and energy saving, high brightness, scattering angle is large, good

APA102C Pinout

APA102C for the three-color RGB LED dimming control string then IC ‘ using the CMOS process ‘ providing three-color RGB LED output driver to adjust the output with 256 gray-scale and 32 brightness adjustment APA102 with two-output WAY, the CLK signal by synchronization so that the crystal cascadepiece of output movements synchronized.


1. The control circuit and the LED share the only power source.
2. Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point.
3. Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not Accumulate.4. The color of the light were highly consistent, cost-effective
