Product specification
Multistandard repertory dialler/ringer with
EEPROM
PCD3330-1
The STO-key will end the programming procedure,
whereas after the LNR-key a new byte can be selected to
have the required bit changed.

Operation mode overview
The PCD3330-1 has in total five operation modes:
standby, conversation, ringer, dialling and programming.
The state diagram is given in Fig.7.
When both CE/RF and the HOOK input are LOW the
PCD3330-1 goes to the standby mode, in which the
contents of the redial register is refreshed, the oscillator
switched off and the device enters the low current state.
A HIGH state on the CE/RF and/or the HOOK input will
cause a complete initialization of the PCD3330-1 which
means setting of the I/O pins, clearing of the RAM and
reloading the EEPROM contents into it.

MODE SELECTION BY PIN
The PCD3330-1 has two dialling modes, pulse dialling and
Dual Tone Multi Frequency (DTMF). These can be
selected via the PD/DTMF input in the following way:
PD/DTMF = HIGH (V
DD
) = DTMF mode.
PD/DTMF = LOW (V
SS
) = pulse mode.
The controller accepts the information also during manual
dialling. Switching the input to the pin PD/DTMF changes
the dialling mode after transmitting the digit in progress.
