W91561LN

Manufacturer Part Number
W91561LN
Description
3-memory tone/pulse dialer with keytone, lock and handfee functions
Manufacturer
Winbond
Datasheet
GENERAL DESCRIPTION
The W91560N series are tone/pulse switchable telephone dialers with three memories, keytone or
lock, and handfree dialing control. These chips are fabricated using Winbond's high-performance
CMOS technology and thus offer good performance in low-voltage, low-power operations.
FEATURES
DTMF/pulse switchable dialer
Two by 32 digit redial and save memory
Three by 16 digit one-touch direct repertory memory
Pulse-to-tone (*/T) keypad for long distance call operation
Cascaded dialing
Uses 5
Easy operation with redial, flash, pause, and */T keypads
Pause, P T (pulse-to-tone) can be stored as a digit in memory
On-hook debounce time: 150 mS (Unlock Mode), 200 mS (Lock Mode)
0 or 9 dialing inhibition pin for PABX system or long distance dialing lock out
Dialing rate (10 ppS or 20 ppS) selectable by bonding option
Minimum tone output duration: 93 mS
Minimum intertone pause: 93 mS
Pause time: 3.6 sec.
300 mS off-hook delay in lock mode ( DP remains low for 300 mS while off hook)
Flash break time (73 mS, 100 mS, 300 mS, or 600 mS) selectable by keypad; pause time is 1.0S
Make/break ratio (40:60 or 33.3:66.7) selectable by MODE pin
Key tone output for valid keypad entry recognition
On-chip power-on reset
Uses 3.579545 MHz crystal or ceramic resonator
18 or 20-pin dual-in-line plastic package
