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 x 3 one-touch memory, 16-digit x 10 two-touch memory dialing, and 32-digit x 2 redial and save memory. These dialers also provide a secrecy key, flash, two-way handfree dialing, one-key redial, hold and lock functions.

PIN DESCRIPTION
SYMBOL Column, Row Inputs PIN 44-49 & 50-53 I/O I FUNCTION The keyboard input may be used with either the standard 4 x 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. T/P MUTE 40 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. 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. 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. 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.

LOCK
64
I
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. The telephone is reinitialized by a reset. The following table describes the functions of the LOCK pin:
LOCK PIN Floating VDD VSS FUNCTION Normal dialing "0", "9" dialing inhibited "0" dialing inhibited
TEST
37
I
In normal operation, pulling the TEST pin to VDD inhibits the single tone. In testing operation, pulling the TEST pin to VSS enables a single tone to be created by pressing two keys simultaneously, and all of the timing parameters for pulse dialing are faster than in normal operation. Power supply pin for LCD driver. A 1F capacitor is connected between VLCD and VSS. CP is the voltage control capacitor positive pin. CN is the voltage control capacitor negative pin. A 1 F capacitor is connected between these two pins.

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: Example 2: Example 3: Normal dialing + Repertory dialing 1 + Normal dialing + + + Repertory dialing 2 Repertory dialing 2 +... +... +...
Repertory dialing 1 Redialing +
Normal dialing
Repertory dialing
2. Normal dialing, redialing, or repertory dialing as represented by each rectangle above is treated as one sequence. 3. At most 32 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 valid only as the first key-in, however. 5. If ON HOOK , OFF HOOK , R is entered, then the cascaded dialing sequence described
in the examples above will be dialed out only if the total number of digits does not exceed 32. If the sequence exceeds 32 digits then 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.

4. If
ON HOOK
,
OFF HOOK
,
R 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 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: ON HOOK , OFF HOOK , R , then redialing will be executed only if the total number of
digits does not exceed 32. Otherwise, the redialing is inhibited. 3. If there had been n cascaded sequences with a total of 30 digits dialed, then for the (n+1)th cascaded sequence, one 2-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 32 digits of cascaded dialing have been completed, mixed dialing can be added.
