FEATURES
PCD3310; PCD3310A
•
On-chip voltage reference for supply and temperature
independent tone output
•
On-chip filtering for low output distortion
(CEPT compatible)
•
On-chip oscillator uses low-cost 3.58 MHz (TV colour
burst) crystal or piezo resonator
•
Uses standard single-contact or double-contact
(common left open) keyboard
•
Keyboard entries fully debounced
•
Flash (register recall) output.

GENERAL DESCRIPTION
•
Pulse, DTMF and ‘mixed mode’ dialling
•
Mixed mode dialling: start with pulse dial, end with
DTMF dial (e.g. for control of DTMF user equipment via
a pulse network)
•
23-digit memory stores last number dialled, or number
noted during conversation (notepad)
•
Redial of both PABX and external calls
•
Supports 16 dial keys: 0 to 9,
∗,
# A, B, C, and D
•
Supports 4 function keys:
– Program (P) used to input notepad numbers
– Flash (FL) allows re-dialling without on-hook
– Redial (R) recalls and redialls stored number
– Change from pulse dial to DTMF dial in
mixed mode (>)
•
DTMF timing:
– for manual dialling, maximum duration burst/pause
intervals are user-determined, but at least minimum
duration burst/pause intervals are ensured
– for redial, minimum duration burst/pause intervals are
used

The PCD3310 and PCD3310A are single-chip silicon gate
CMOS integrated circuits. They are dual-standard diallers
for pulse or dual tone multi-frequency (DTMF) dialling, with
on-chip oscillators suitable for use with 3.58 MHz crystals.
Input data is derived from any standard matrix keyboard
for dialling in either the pulse or DTMF mode.
Numbers up to 23 digits can be retained in RAM for
dialling/redialling.

Notes
1. Pulse frequency 10 Hz, inter-digit pause (t

) = 840 ms.
2. Note that the PCD3310P; 10T and the PCD3310AP; 10AT differ only in the break/make ratio in pulse dialling.
The break/make times equate to mark-to-space ratios of 2 : 1 and 3 : 2 respectively.
