W91F810N SERIES
23-FLASH MEMORY TONE/PULSE DIALER WITH
HANDFREE, LOCK AND HOLD FUNCTIONS
GENERAL DESCRIPTION
The W91F810N is a series of tone/pulse switchable telephone dialers with 23-falsh 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 flash-memory
Twenty by 32 digits one-touch direct or two-touch indirect repertory flash-memory
The read-write times: 104
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, PT (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-pin 400 mil, 24-pin 600 mil or 28-pin 600 mil dual-in-line plastic package
