W91810N SERIES

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

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.
