Revision A2
GENERAL DESCRIPTION
The W91510N series are Si-gate CMOS ICs that provide the necessary signals for tone or pulse
dialing. The W91510N series provide one-key redial, handfree dialing, key tone, save, and redial
functions.
FEATURES
DTMF/pulse switchable dialer
Two by 32-digit redial and save memory
Pulse-to-tone (*/T) keypad for long distance call operation
Uses 5
4 keyboard
Easy operation with redial, flash, pause, and */T keypads
Pause, pulse-to-tone (*/T) can be stored as a digit in memory
On-hook debounce time: 150 mS
Dialing rate (10 ppS or 20 ppS ) selectable by bonding option
Minimum tone output duration: 93 msec.
Minimum intertone pause: 93 msec.
Flash break time (73, 100, 300, 600 msec.) selectable by keypad; pause time is 1.0 sec.
On-chip power-on reset
Uses 3.579545 MHz crystal or ceramic resonator
Packaged in 18 or 20-pin plastic DIP

The keyboard inputs may be used with either a standard
5

A) keyboard. Electronic input from a
C can also be
used. A valid key-in is defined as a single row being
connected to a single column.

O
The T/P MUTE is a conventional CMOS N-channel
open drain output.
The output transistor is switched on during dialing
sequence, one-key redial break, and flash break time.
Otherwise, it is switched off.

2. The dialer will execute a flash break time of 600 mS (F1), 100 mS (F2), 300 mS (F3), or 73 mS
(F4).
In each case, the flash pause time is 1.0 sec. before
the next digit is dialed out.
3. Flash key cannot be stored as a digit in memory. The flash key has first priority among keyboard
functions.
4. The system will return to the initial state after the flash pause time is finished.
5. The flash function timing diagram is shown in Figure 7.
