Serially Interfaced, 8-Digit LED Driver  
DATA SHEET  
AS1100  
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 AS1100  
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 AS1100  
can be reset by software and an external clock can be used.  
Several test modes support easy debugging.

The AS1100 is an LED driver for 7 segment numeric  
displays of up to 8 digits. The AS1100 can be programmed  
via a conventional 4 wire serial interface. It includes a BCD  
code-B decoder, a multiplex scan circuitry, segment and  
display drivers and a 64 Bit memory. The memory is used to  
store the LED settings, so that continuous reprogramming is  
not necessary.
