23-MEMORY TONE/PULSE DIALER WITH
HANDFREE, LOCK AND HOLD FUNCTIONS
GENERAL DESCRIPTION
The W91810N is a series of tone/pulse switchable telephone dialers with 23 memory, keytone, hold,
lock, mute, volume control and handfree dialing control features. These chips are fabricated using
Winbond's high-performance CMOS technology and thus offer good performance in low-voltage, low-
power operations.
FEATURES
· Tone/pulse switchable dialer
· Two by 32 digits redial and save memory
· Three by 32 digits one-touch direct repertory memory
· Twenty by 32 digits one-touch direct or two-touch indirect repertory memory
· Pulse-to-tone (*/T) keypad for long distance call operation
· Chain dialing
´
´
· Uses 6 6 or 7 7 keyboard
· Easy operation with redial, flash, pause, and */T keypads
®
· Pause, P T (pulse-to-tone) can be stored as a digit in memory
· Dialing rate: 10 or 20 ppS by mask option
· Minimum tone output duration: 93 mS
· Minimum intertone pause: 93 mS
· Pause time: 3.6 sec.
· Flash break time (73 mS, 100 mS, 300 mS, or 600 mS) selectable by keypad; pause time is 1.0 S
· Make/break ratio (2:3 or 1:2) selectable by MODE pin
· Mute key for speech network mute
· No key will be accepted except the "HOLD" key when in the Hold mode
· 4-level volume control by V1 and V2 pin - default value is zero
· Key tone output for valid keypad entry recognition
· On-chip power-on reset
· Uses 3.579545 MHz crystal or ceramic resonator
· 22, 24 or 28-pin dual-in-line plastic package
· The different dialers in the W91810N series are shown in the following table:

The key tone output is a conventional CMOS
inverter. The key tone is generated when any valid
key is pressed; the KT pin generates a 1.2 KHz
square wave at 35 mS. When no key is pressed,
the KT pin remains in low state.

The function of this terminal is to prevent "0"
dialing and "9" dialing under PABX system long
distance call control. When the first key input after
reset is 0 or 9, all key inputs, including the 0 or 9
key, become invalid and the chip generates no
output. The telephone is reinitialized by a reset.
