AS1130 - 132-LED Cross-Plexing Driver

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.

Key Features

  • a very low shutdown and operational current. The device offers a programmable IRQ pin. Via a register it can be set on what event (CP request, Interface time out, Error-detection, POR, End of Frame or End of Movie) the IRO is triggered. Also hardware scroll Function is implemented in the AS1130. The device is available in an ultrasmall 20-pin WL-CSP and an easy to solder 28-pin SSOP/TSSOP package. Figure 1. AS1130 - Typical.

Datasheet AS1130 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 small animations automatically. The AS1130 operates from 2.7V to 5.
