13-MEMORY TONE/PULSE DIALER WITH SAVE,
KEYTONE, LOCK, AND HANDFREE FUNCTIONS
Publication Release Date: February 1999
- 1 -
Revision A4
GENERAL DESCRIPTION
The W91530N series are tone/pulse switchable telephone dialers with 13 memories, keytone or lock,
and handfree dialing control. These chips are fabricated using Winbond's high-performance CMOS
technology and thus offer good performance in low-voltage, low-power operations.
FEATURES
DTMF/pulse switchable dialer
Two by 32 digits redial and save memory
Three by 16 digits one-touch direct repertory memory
Ten by 16 digits two-touch indirect repertory memory
Pulse-to-tone (*/T) keypad for long distance call operation
Cascaded dialing
Uses 5
5 keyboard
Easy operation with redial, flash, pause, and */T keypads
Pause, P
T (pulse-to-tone) can be stored as a digit in memory
0 or 9 dialing inhibition pin for PABX system or long distance dialing lock out
Dialing rate (10 ppS or 20 ppS) selectable by bonding option
Minimum tone output duration: 93 mS (W91534AN: 87 mS)
Minimum intertone pause: 93 mS (W91534AN: 87 mS)
Pause time: 3.6 sec.
300 mS off-hook delay in lock mode (
DP
remains low for 300 mS while off hook)
Flash break time (73 mS, 100 mS, 300 mS, or 600 mS) selectable by keypad; pause time is 1.0 mS
Make/break ratio (2:3 or 1:2) selectable by MODE pin
Key tone output for valid keypad entry recognition
On-chip power-on reset
Uses 3.579545 MHz crystal or ceramic resonator
18 or 20-pin dual-in-line plastic package

I
The keyboard input is compatible with a standard 5 x 5
keyboard, an inexpensive single contact (Form A)
keyboard, and electronic input.
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 single
tone.

I
A built-in inverter provides oscillation with an inexpensive
3.579545 MHz crystal. The oscillator ceases when a
keypad input is not sensed. The crystal frequency deviation
is 0.02%.

The T/P MUTE is a conventional CMOS N-channel open

The output transistor is switched on low level during dialing
sequence (both pulse and tone mode). Otherwise, it is
switched off.

Pulling mode pin to V

places dialer in pulse mode (10

Leaving mode pin floating places dialer in pulse mode (10

ppS).
HKS
10
12
I
The HKS (hook switch) input is used to sense whether the
handset is on-hook or off-hook.
In on-hook state, HKS = 1: chip is in sleeping mode, no
operation.
In off-hook state, HKS = 0: chip is enabled for normal
operation.
HKS pin is pulled to V
DD
by internal resistor.

The key tone output is a conventional CMOS inverter. The
key tone is generated when any valid 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.

I
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.
