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.
