132-LED Cross-Plexing Driver with scrolling Function 1 General Description The AS1130 is a pact LED driver for 132 single LEDs. The devices can be programmed via an I²C patible interface. The AS1130 offers a 12x11 LED-Matrix with 1/12 cycle rate. The required lines to drive all 132 LEDs are reduced to 12 by using the cross-plexing feature optimizing space on the PCB. The whole LEDMatrix driving 132 LEDs can be analog dimmed from 0 to 30mA in 256 steps (8 bit). Additionally each of the 132 LEDs can be dimmed individually with 8bit allowing 256 steps of linear dimming. To reduce CPU usage up to 6 frames can be stored with individual time delays between frames to play...
