AS2578 /B

TELEPHONE CONTROLLER WITH

13 MEMORIES AND 2-WIRE BUS

Austria Mikro Systeme International

KeyFeatures

General Description

The AS2578 /B are a versatile repertory LD/MF diallers

with a melody generator, a ring frequency discriminator

❑ Low operating voltage

❑ Low current consumption, standby ≤ 0.1 µA

❑ Oscillator using Xtal or ceramic resonator(3.58MHz)

❑ Serial interface to external EEPROM

❑ Consistent, simple and usable procedures

❑ The settings are programmed via the keyboard and

stored in EEPROM or set by pin options

Dialler:

❑ Data protection with 20 digit FIFO

❑ Sliding cursor protocol with comparison

❑ Automatic pause generation

❑ Temporary MF select via keyboard

❑ 30 digit LNR (Last Number Redial)

❑ 13 x 20 digit memory (RAM) on chip

ToneRinger:

and a 2-wire interface to EEPROM. Together with the

AS2520/1, the AS2578 /B form a coherent basis for a

fully electronic telephone with a wide range of options.

The AS2578 /B are especially designed to adapt to

different PTT specifications. A RAM is on chip for last

number redial, 3 direct dial and 10 numbers with

abbreviated dialling. To allow easy use under a PABX,

the device incorporates automatic pause insertion and

slidingcursorprocedureasselectableoptions(AS2578)

orcentrexkeys(AS2578B). Thedevicecanbeusedwith

or without EEPROM as appropriate. When an EEPROM

is connected, all RAM content is stored in the EEPROM

by power loss.

❑ Ring frequency discrimination

❑ 3 tone melody with 4 different repetition rates

❑ Volume of melodies can be set in 4 steps

The circuit provides the possibility to set different modes

of operation (LM codes) via the keyboard or via pin

options, e.g. default signalling mode, automatic pause

insertion, flash or ground loop and settings of volume

and melodies.

Package

Available in 28 pin DIP and PLCC.
