2 GENERAL DESCRIPTION

The PCD3330-1 is a mixed-mode multistandard repertory

dialler/ringer IC fabricated in a low threshold voltage

CMOS technology.

The (maximum 13) repertory numbers, redial and various

country specifications are stored in EEPROM so that

memory retention is guaranteed for 10 years without using

a battery back-up.

National telecommunications specifications can be fulfilled

by changing a few bytes in EEPROM which contain the

different telephone timing and dialling procedures.

The two on-chip tone generators are used for Dual Tone

Multi-Frequency (DTMF) dialling, and for generating a

melody during ringing, which is activated when a correct

incoming ringer frequency is detected.

As an output transducer for the ringer, a loudspeaker

(ringer out via tone output) or a PXE (ringer out via the

special ringer output which generates square wave ringer

tones with a peak-to-peak voltage of VDD to VSS) can be

used.

The operating supply voltage is 1.8 V (2.5 V in EEPROM

erase/write and DTMF and ringer mode) to 6.0 V with a low

current consumption in all operating modes: standby,

conversation, dialling, programming and ringer.
