W91570DN SERIES

23-MEMORY TONE/PULSE DIALER WITH

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.

· Uses 6 ´ 10 keyboard

· Pause, Pulse-to-tone (*/T) and flash can be stored as a digit in memory

· Minimum tone output duration: 87 mS

· Minimum intertone pause: 87 mS

· Tone/Pulse mode pin selectable

· Make/Break ratio pin selectable

· Dialing rate (10 or 20 ppS) pin selectable

· Pause time (2.0 or 3.6 Sec) selectable by keypad

· Flash break time (100, 300, 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]

· Uses 3.579545 MHz TV quartz crystal or ceramic resonator

· Uses 32768 Hz crystal as RTC frequency base

· Packaged in 80-pin plastic QFP with RTC

· Provides one-key-redial and auto-redial functions

· Switchable 24-hour clock or 12-hour clock with p.m. mode

· 0 or 9 dialing inhibition pin for PABX systems or long distance dialing lock out

· On-hook debounce: 150 msec in normal mode and 20 msec in lock mode

· Off-hook delay 300 mS in lock mode (i.e. DP will keep low for 300 mS while off hook)

· First key-in delay: 300 msec in lock mode

· MUTE key for speech mute

· Cascade and mixed dialing allowed

· The functions of the different dialers in the W91570DN series are shown in the following table:

The keyboard inputs may be used with either the standard 6´ 10

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.

I,

O

A built-in inverter provides oscillation with an inexpensive

3.579545 MHz crystal or ceramic resonater.

XT1, XT

The oscillator ceases when a keypad input is not sensed after

chip enable and dialing is finished. The crystal frequency

deviation is ±0.02%.

T/P MUTE

H/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,

auto redial break and flash break. Otherwise, it is switched off.

16

15

O

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

pulse dialing, one-key redial break, auto redial break, flash

break, hold, and mercury functions, this pin will output an active

high. It remains in a low state at all other times.

O

I

KMUTE

HKS

The KMUTE is a CMOS N-channel open drain output. The

output transistor is switched on only during mute function.

Otherwise, it is switched off.

Hook switch input.

HKS = VDD or floating: On-hook state. Chip in sleeping mode,

no operation.

HKS = VSS: Off-hook state. Chip enable for normal operation.

HKS pin is pulled to VDD by internal resistor.

This pin is a CMOS N-channel open drain output. The flash key

will cause DP / C10 to go active in either pulse mode or tone

DP / C10

mode. In lock mode, the DP / C10 keeps low for 300 mS during

off-hook delay time (If first off-hook occured after power-on

reset, the DP / C10 will keep high for 100ms then go low 200

mS. It will be recovered when first key-in was accepted). 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. Detailed timing

diagram for tone mode is shown in Figure 2(a), 2(b), 2(c), 2(d).

LOCK

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 "0" or "9" key,

become invalid, and the chip generates no output.

Cascaded and Mixed Dialing

Cascaded Dialing

1. Definition of cascaded dialing:

In cascaded dialing, a new sequence may be pressed before the previous sequence has been sent

out completely. The following are examples of cascaded dialing:

Example 1: Normal dialing + Repertory dialing 1 + Repertory dialing 2 +...

Example 2: Repertory dialing 1 + Normal dialing + Repertory dialing 2 +...

Example 3: Redialing + Normal dialing + Repertory dialing 1 +...

2. Normal dialing, redialing, or repertory dialing as represented by each rectangle above is treated as

one sequence.

3. At most 64 digits are allowed in cascaded dialing, but there is no limitation on the number of

sequences.

4. The content of cascaded dialing may a combination of normal dialing, redialing, and repertory

dialing. Redialing is vaild only as the first key-in, however.

,

OKR

5. If ON HOOK

,

OFF HOOK

is entered, then the cascaded dialing sequence

described in the above examples will be dialed out only if there are not more than 32 digits. If the

sequence exceeds 32 digits then the redialing is inhibited.

Mixed Dialing

1. Definition of mixed dialing:

The examples of cascaded dialing given above are also examples of mixed dialing except that in

mixed dialing a new sequence may be accepted only when the previous sequence has been dialed

out completely.

2. There is no limitation on the number of digits and sequences in the mixed dialing.

3. The content of mixed dialing may be a combination of normal dialing, memory dialing, or one-key

redialing.

,

OKR

4. If ON HOOK

,

OFF HOOK

is entered, then the mixed dialing sequence

described in the above examples will be dialed out only if the total number of digits does not

exceed 32. If the total exceeds 32 digits, then redialing is inhibited.

Combining of Cascaded and Mixed Dialing

1. Cascaded dialing and mixed dialing may be combined, and each follows the rules described

above.

2. To apply redialing to combinations of cascaded and mixed dialing:

,

OKR

ON HOOK

,

OFF HOOK

then redialing will be executed only if the total number of

digits does not exceed 32. Otherwise, the redialing is inhibited.

- 16 -

W91570DN SERIES

3. If there had been n cascaded sequences with a total of 60 digits dialed, then for the (n+1)th

cascaded sequence, one 4-digit normal dialing sequence or one complete repertory dialing

sequence (length up to 32 digits) can be dialed. The (n+2)th sequence will not be accepted for

cascaded dialing.

4. After a total of 64 digits of cascaded dialing have been completed, mixed dialing can be added.
