W91F810N SERIES

23-FLASH MEMORY TONE/PULSE DIALER WITH

HANDFREE, LOCK AND HOLD FUNCTIONS

GENERAL DESCRIPTION

The W91F810N is a series of tone/pulse switchable telephone dialers with 23-falsh memory, keytone,
hold, lock, mute, volume control and handfree dialing control features. These chips are fabricated
using Winbond's high-performance CMOS technology and thus offer good performance in low­voltage, low-power operations.

FEATURES

• Tone/pulse switchable dialer

• Two by 32 digits redial and save memory

• Three by 32 digits one-touch direct repertory flash-memory

• Twenty by 32 digits one-touch direct or two-touch indirect repertory flash-memory

• The read-write times: 10

• Pulse-to-tone (*/T) keypad for long distance call operation

• Chain dialing

• Uses 6

×

6 or 7 × 7 keyboard

• Easy operation with redial, flash, pause, and */T keypads

• Pause, P

→

T (pulse-to-tone) can be stored as a digit in memory

• Dialing rate: 10 or 20 ppS by mask option

• Minimum tone output duration: 93 mS

• Minimum intertone pause: 93 mS

• Pause time: 3.6 sec.

• Flash break time (73 mS, 100 mS, 300 mS, or 600 mS) selectable by keypad; pause time is 1.0 S

• Make/break ratio (2:3 or 1:2) selectable by MODE pin

• Mute key for speech network mute

• No key will be accepted except the "HOLD" key when in the Hold mode

• 4-level volume control by V1 and V2 pin - default value is zero

• Key tone output for valid keypad entry recognition

• On-chip power-on reset

• Uses 3.579545 MHz crystal or ceramic resonator

• 22-pin 400 mil, 24-pin 600 mil or 28-pin 600 mil dual-in-line plastic package

• The different dialers in the W91F810N series are shown in the following table:

In normal operation, any single button can be

pushed to produce dual tone, pulses, or functions.
Activation of two or more buttons will result in no
response except for a single tone.

3.579545 MHz crystal supplies the oscillator. The
oscillator stops when there is no keypad input. The
crystal frequency deviation is 0.02%.

The T/P

The key tone output is a conventional CMOS

key is pressed; the KT pin generates a 1.2 KHz
square wave at 35 mS. When no key is pressed,
the KT pin remains in low state.

The function of this terminal is to prevent "0"
dialing and "9" dialing under PABX system long
distance call control. When the first key input after
reset is 0 or 9, all key inputs, including the 0 or 9
key, become invalid and the chip generates no
output. The telephone is reinitialized by a reset.

The H/P MUTE is a conventional inverter output.
During pulse dialing, flash break or hold period, this
output is active high; otherwise, it remains in low
state.

Flash key will cause DP to be active in either tone

mode or pulse mode.
The timing diagram for pulse mode is shown in

Figure 1(a, b).
During pulse dialing, this pin remains in a low state

regardless of the keypad input. In tone mode, it will
output a dual or single tone.
