AUTOREDIAL RTC AND LCD DISPLAY FUNCTIONS
GENERAL DESCRIPTION
The W91570DN series ICs are Si-gate CMOS ICs that provide the signals needed for either pulse or
tone dialing. They feature 23 number memories and a 16-digit LCD driver for displaying telephone
numbers and calling time. A real time clock is included to display the time of day. The W91570DN
series is fabricated using CMOS technology providing good performance in low voltage, low power
applications.
