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.

A valid key entry is defined by a single row being connected to a single column. XT1, XT 34, 35 I, O A built-in inverter provides oscillation with an inexpensive 3.579545 MHz crystal or ceramic resonater. 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 16 O 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. 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. 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.

A low pulse on the HFI input pin toggles the handfree control state. Status of the handfree control is listed in the following table: CURRENT STATE Hook SW. HFO Low On Hook Off Hook On Hook Off Hook Off Hook Low High High High Input HFI HFI HFI Off Hook On Hook On Hook NEXT STATE HFO High Low Low Low Low High Dialing Yes No Yes Yes No Yes The HFI pin is pulled to VDD by internal resistor. Detailed timing diagrams are shown in Figure 4(a), 4(b). DP / C10 18 O 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 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). 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).

Pulling the mode pin to VDD places the dialer in pulse mode and the dialing rate is 10 ppS. Floating the mode pin places the dialer in pulse mode and the dialing rate is 20 ppS. -4- W91570DN SERIES Pin Description, continued SYMBOL B/M PIN NO. 11 I/O I FUNCTION Make:Break ratio select pin. If B/M = VDD, the M/B ratio is 40:60. If B/M = VSS, the M/B ratio is 33.3:66.7. The B/M pin is pulled to VDD by internal resistor. LOCK 10 (for all lock version) 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.

A quartz crystal oscillator provides an RTC frequency time base of 32.768 KHz. Either VRTC1 should be connected to a 1.5V battery (W91572DN/576DN) or VRTC2 should be connected to a 3.0V battery(W91574DN/578DN), which supplies the power source for the RTC. In the chip enable state, pulling SET RTC to VSS toggles the RTC set function on/off, when the set function is toggled on, the RTC can be set using the "HOUR" and "MIN" keypads.

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 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. 5. If ON HOOK , OFF HOOK , OKR 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. 4. If ON HOOK , OFF HOOK , OKR 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: ON HOOK , OFF HOOK , OKR 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.
