1 General Description
The AS1105 is an LED driver for 7-segment numeric displays of up
to 4 digits. The AS1105 can be programmed via a conventional 4-
wire serial interface.
The device includes a BCD code-B decoder, a multiplex scan
circuitry, segment and display drivers, and a 32-bit memory. The
memory is used to store the LED settings, so that continuous
reprogrammng is not necessary.
Every individual segment can be addressed and updated separately.
Only one external resistor is required to set the current through the
LED display.
Brightness can be controlled either in an analog or digital way. The
user can choose the internal code-B decoder to display numeric
digits or to address each segment directly.
The AS1105 features an extremely low shutdown current of only
20μA and an operational current of less than 500μA. The number of
visible digits can be programmed as well.
The AS1105 can be reset by software and an external clock can be
used. Several test modes support easy debugging.
AS1105 is offered in a 20-pin SOIC package.
