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.
