GENERAL DESCRIPTION  
The W91510DN series ICs are Si-gate CMOS IC that provide the signals needed for either pulse or  
tone dialing. They feature 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 W91510DN series is fabricated using  
CMOS technology and thus provide good performance in low voltage, low power applications.  
FEATURES  
· One by 32 digits for redial  
· 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  
· Minimum intertone pause: 87 mS  
· Tone/pulse mode pin selectable  
· Make/break ratio pin selectable  
· Dialing rate: 10 ppS  
· Pause time: 3.6 Sec.  
· 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]  
· On-chip power-on reset and clear LCD  
· Uses 3.579545 MHz TV quartz crystal or ceramic resonator  
· Uses 32768 Hz crystal as RTC frequency base  
· Packaged in 64-pin plastic QFP with RTC  
· Switchable 24-hour clock or 12-hour clock with p.m. mode by keypad  
· 0 or 9 dialing inhibition pin for PABX systems or long distance dialing lock out  
· On hook debounce: 150 mS in normal mode and 20 mS in lock mode  
· Off-hook delay 300 mS in lock mode (DP will keep low for 300 mS while off hook except the first  
off hook after power on reset that DP will keep high for 100 mS then go low for 200 mS)  
· First key-in delay: 300 mS in lock mode  
· Mixed dialing allowed
