AS1130-BSS - LED DVR DOT MATRIX SSOP28

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.
