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
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.

Applications
The AS1130 is ideal for dot matrix displays in mobile phones,
personal electronics and toys.
