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 V
DD
to V
SS
) 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.
