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: 3.6 Sec. (2.0 Sec. for W91564DNF and W91565DNF)

• 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]

• Memory check function

• 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

• 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 (

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

• Packaged in 64-pin plastic QFP with RTC

• The functions of the different dialers in the W91560DN series are shown in following table:

single column.

3.579545 MHz crystal or ceramic resonater.
The oscillator ceases when a keypad input is not sensed after the

chip is enabled and dialing is finished. The crystal frequency
deviation is ±0.02%.

The T/P

is a conventional CMOS N-channel open drain
output.
The output transistor is switched on low level during the dialing
sequence (both pulse and tone mode), one-key redial break and
flash break. Otherwise, it is switched off.

O The H/P MUTE is a conventional CMOS inverter output, During

pulse dialing, one-key redial break, flash break and hold functions,
this pin will output an active high.

It remains in a low state at all other times.

I The LOCK pin is used to prevent "0" or "9" dialing under PABX

system long distance call control. When the first key input after
reset is "0" or "9", all the key inputs, including the "0" or "9" key,
become invalid, and the chip generates no output.

The telephone is reinitialized by a reset.
