W91550DN SERIES
13-MEMORY TONE/PULSE DIALER
WITH LCD AND LOCK FUNCTIONS
GENERAL DESCRIPTION
The W91550DN series are Si-gate CMOS IC tone/pulse switchable dialers containing 13 number
memories and a 10-digit LCD driver for displaying telephone numbers and calling time, including a
16-digit × 3 one-touch memory, 16-digit × 10 two-touch memory dialing, and 32-digit × 2 redial and
save memory. These dialers also provide a secrecy key, flash, two-way handfree dialing, one-key
redial, hold and lock functions.
FEATURES
• Tone/pulse switchable dialer
• Two by 32-digit redial and save memory (or mercury memory)
• Three by 16-digit one-touch direct repertory memory
• Ten by 16-digit two-touch indirect repertory memory
• Memory check function
• Save/mercury function selected by pin option
• Typical interdigit pause (IDP): 800 msec (10 ppS) in pulse mode
• Uses 4 × 7 keyboard
• Mute key for secrecy control
• Minimum tone output duration/inter-tone pause: 87/87 mS
• Flash pause time: 1.2 sec.
• Flash break time (98, 300, 600 msec) selectable by keypad
• Pause time (2.0, 3.6, 4.0 sec.) selectable by mask option
• Pulse-to-tone (*/T) keypad for long distance call operation
• 0 or 9 dialing inhibition pin for PABX system or long distance dialing lock out
• Make/break ratio selected by pin option
• Built-in 10-digit LCD driver for telephone number display and calling time (1/3 duty, 1/2 bias)
• Built-in calling time from (00:00) to (59:59)
• On-chip power-on reset and clear LCD
• On hook debounce: 250 msec in normal mode (20 msec in lock mode)
• First key-in delay: 300 msec in lock mode
• Uses 3.579545 MHz crystal or ceramic resonator
• Packaged in 64-pin QFP
• The different dialers in the W91550DN series are shown in the following table:

I/O FUNCTION
I The keyboard input may be used with either the standard 4 × 7
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
3.579545MHz crystal. Most crystals do not vary by more than 0.02%.
The oscillator oscillates in off-hook or handfree mode but oscillation
ceases in on-hook mode or when the handfree mode is released.
O The T/P MUTE is a conventional CMOS N-channel open drain
output. The output transistor is switched on during pulse and tone
mode dialing sequences and flash breaks. Otherwise, it is switched
off.
O The HPM MUTE is a conventional CMOS inverter output. During
pulse dialing, flash break, hold, and mercury mute functions, this pin
will output an active high. Otherwise, it remains in a low state.
O The KMUTE is a CMOS N-channel open drain output. The output
transistor is switched on only during the mute function. Otherwise, it is
switched off.
I Pulling mode pin to VSS places the dialer in tone mode.
Pulling mode pin to VDD places the dialer in pulse mode.
Pulse or tone mode can be selected any time.
I Hook switch input.
HKS = VDD: 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.
DP 42 O This pin is a CMOS inverter output. The timing diagram is shown as
Figure 1(a), 1(b), 1(c), 1(d). Flash key will cause DP to go active in
either pulse mode or tone mode.
