Data Sheet AS1100

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.

Applications

General Description

Bar-Graph Displays

Industrial Controllers

Panel Meters

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.
