Data Sheet  
AS2574B  
20 NUMBER ONE TOUCH DIALLER WITH  
SERIAL BUS FOR DISPLAY DRIVER  
Austria Mikro Systeme International  
General Description  
KeyFeatures  
The AS2574B is an integrated CMOS device for feature  
telephones. It is a very versatile LD/MF dialler with serial  
interfacetoadisplaydriver. Thedeviceisdesignedtobe  
used in a wide variety of applications together with the  
companion display driver, AS2590.  
❑ Low operating voltage (2.5V to 5.5V)  
❑ Low current consumption (typ. 200 µA in LD mode)  
❑ Oscillator using ceramic resonator (681 kHz)  
❑ MF level independent of supply voltage  
❑ Direct ´wake-up´ from keyboard  
❑ Automatic Call Progress by direct memory key  
❑ Data protection with 8 digit FIFO  
The on chip RAM can contain up to 20 memories (each  
with maximum 18 digits), a 36 digit Last Number Redial  
(LNR) and an 18 digit notepad. Access to the 20 memo-  
ries is either with direct keys, abbreviated dial code or a  
combination of both. The AS2574B provides a unique  
feature, Automatic Call Progress (ACP), on all memory  
keys, i.e. the circuit automatically seizes the line and  
waits for the dial tone and dials the number just by  
pressing any of the memory keys (including LNR).  
❑ Sliding cursor protocol with comparison  
❑ Diode options for different PTT requirements  
❑ Automatic pause generation after access code  
❑ Temporary MF select via keyboard  
❑ 36 digit LNR (Last Number Redial)  
❑ 20 memories addressable with direct keys and the  
2nd key or indirect with a MEM key  
❑ Notepad  
❑ Serial interface to display driver AS2590  
❑ Consistent, simple and useable procedures  
❑ Input for dial tone recognizer  
The circuit features 2 different access code procedures  
to allow easy use under a PABX. A dial tone input  
enables the use of a dial tone recognizer.
