Overview
Preliminary W91560DN SERIES 3-MEMORY TONE/PULSE DIALER WITH RTC AND LCD DISPLAY FUNCTIONS GENERAL DESCRIPTION The W91560DN series ICs are Si-gate CMOS ICs that provide the signals needed for either pulse or tone dialing.
They feature 3 number memories and a 12/16-digit LCD driver for displaying telephone numbers and calling time.
A real time clock is included to display the time of day.
The W91560DN series is fabricated using CMOS technology and thus provide good performance in low voltage, low power applications.
FEATURES • One by 32 digits for redial • Three by 32 digits for one-touch direct repertory memory • Uses 5 × 6 keyboard • Pause, Pulse-to-tone (*/T) can be stored as a digit in memory • Flash can be stored as a digit in memory when in store mode • Minimum tone output duration: 87 mS (81 mS for W91564DNF and W91565DNF) • Minimum intertone pause: 87 mS • Tone/Pulse mode pin selectable • Make/Break ratio pin selectable • Dialing rate: 10 ppS • Pause time: ...
