greeled electronic ltd INK1002 rgb led (geINK1002rgb) data sheet of INK1002 rgb led (geINK1002rgb) www.gree-leds.com sales@gree-led.com features applications z ink1003 and rgb led chips are packaged in a single 5050 led package to form a independent pixel z independent led and driver ic power supply to enhance the reliability and flexibility; z built-in signal reconstruct circuit ensures up to 2048 lamps cascading with no distortion z single-wire control, chips can tranceive signal with only one wire. z wide operating voltage:3.3~5.4v z high gray level, 256 gray levels, the lamp can display more than 16777216 colors. z low output current deviation: between channels in a single chip: 1% between chips: 3% z data frequency range wide: 800khz z schmitt trigger input high reliability, esd susceptibility high: hbm 8kv z led decorative lighting z indoor/outdoor led video or massage display z un-regular led displays z high pixel density led strips z led strips operate between 5~12v description INK1002 is a digital full color smd5050 led,which integrates high quality led chips and ink1003 single-wire cascadable led driver ic in a small smd5050 led package. its dimension is the same as the usual smd5050 led. the high uniformity driver ic ink1003 ensures the low deviation of this digital led. the communication protocol of INK1002 is ?auto-zero? code. once the chip is reset, di pin is ready to receive gray level data transferred by the controller, when the first 24-bit data package is received by the first chip, the later received data will be reconstructed by the chip and transferred from do pin after about 150ns delay to the next chip. with this method, the cascading led lamps are unlimited, only limited by the data transferring rate. INK1002 is low voltage driver, friendly to environment, high efficacy, long life time, and the application board is also minimized, easier for user. its operating temperature range is -40~85 z pin configuration fig1 5050 package z typical application circuit greeled electronic ltd
