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

•
Flash break time (73 mS, 100 mS, 300 mS or 600 mS) selectable by keypad
Built-in 12 or 16-digit LCD driver (1/4 duty, 1/3 bias) selectable by mask option
•
•
Built-in calling timer from [00:00] to [59:59]

Preliminary W91560DN SERIES PIN DESCRIPTION SYM. PIN NO. FUNCTION The keyboard inputs may be used with either the standard 5 × 6 Row, 18−21, Column keyboard, an inexpensive single contact (form A) keyboard or 13−17 Inputs electronic input. A valid key entry is defined by a single row being connected to a single column. - Page 4 Preliminary W91560DN SERIES Pin Description, continued SYM. PIN NO. FUNCTION MODE Pulling the mode pin to V places the dialer in tone mode. Pulling the mode pin to V places the dialer in pulse mode (10 ppS, M/B = 2:3).
