132-LED Cross-Plexing Driver with scrolling Function
1 General Description
The AS1130 is a compact LED driver for 132 single LEDs.
The devices can be programmed via an I²C compatible 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 sm...
