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 LED-

Matrix 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 8-

bit 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 5.5V and 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 a ultrasmall 20-pin WL-CSP and an easy

to solder 28-pin SSOP package.
