Revision A2

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 (

will keep low for 300 mS while off hook except the first

off hook after power on reset that

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

FUNCTION

Row,

Column

Inputs

21,

The keyboard inputs may be used with either the standard 5

keyboard, an inexpensive single contact (form A) keyboard or
electronic input.

A valid key entry is defined by a single row being connected to a
single column.

XT1,

XT1

22, 23

I, O

A built-in inverter provides oscillation with an inexpensive
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%.

T/P

MUTE

The T/P

MUTE

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.

H/P

MUTE

(W91560DNF,

W91562DNF,
W91564DNF,

W91565DNF

only)

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.

LOCK

(W91561DLNF,

W91563DLNF

only)

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.

The following table describes the functions of the LOCK pin:

The timing diagram is shown as Figure 1(a), 1(b), 1(c), 1(d).

DTMF

In pulse mode, this pin remains in low state at all times.
In tone mode, it will output a dual or single tone. The detailed
