AS1130

132-LED Cross-Plexing Driver with

Scrolling Function

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

0mA 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 Timeout,

Error-detection, POR, End of Frame or End of Movie) the IRQ 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.
