Data Sheet  
AS2590  
LC DISPLAY DRIVER WITH 18 DIGITS,  
6 SYMBOLS AND CLOCK/TIMER  
Austria Mikro Systeme International  
Key Features  
General Description  
Very low operating current, typ. 30 µA @ 3V  
Low power oscillator using 32.768 kHz Xtal  
2-wire interface compatible to AS2574B  
18 digits by 7 segments  
The AS2590 is an integrated CMOS device for driving a  
liquidcrystaldisplayintendedforuseintelephones. The  
2-wire serial interface is compatible to the dialler  
AS2574B.  
6 symbols  
24 hour clock showing hours and minutes  
Timer automatically showing elapsed time in  
minutes and seconds after each telephone  
conversation  
The extreme low operating current allows the circuit to  
be operational also during on-hook which is necessary  
in order to the use of the clock function. In on-hook  
condition the circuit can be supplied by a small leakage  
current from the telephone line or from a small 3V  
battery.  
33 LCD segment outputs and 4 LCD backplane  
outputs  
4 times multiplex mode with a cycle time of 128 Hz  
Mode select pin for selecting clock function  
Whether the oscillator shall continue operating or be  
stopped during on-hook is determined by the mode pin,  
MS.  
Package  
Available in 48 pin DIP and 52 pin PLCC.
