Preliminary W91510DN SERIES TONE/PULSE DIALER WITH RTC AND LCD DISPLAY FUNCTIONS
GENERAL DESCRIPTION
The W91510DN series ICs are Si-gate CMOS IC that provide the signals needed for either pulse or tone dialing. They feature a 12/16-digit LCD driver for displaying telephone numbers and calling time. A real time clock is included to display the time of day. The W91510DN series is fabricated using CMOS technology and thus provide good performance in low voltage, low power applications.
FEATURES
* One by 32 digits for redial * Uses 5 x 6 keyboard * Pause, pulse-to-tone (*/T) can be stored as a digit in memory * Flash can be stored as a digit in memory when in store mode * Minimum tone output duration: 87 mS * Minimum intertone pause: 87 mS * Tone/pulse mode pin selectable * Make/break ratio pin selectable * Dialing rate: 10 ppS * Pause time: 3.6 Sec. * Flash break time (73 mS, 100 mS, 300 mS or 600 mS) selectable by keypad * Built-in 12 or 16-digit LCD driver (1/4 duty, 1/3 bias) selectable by mask option * Built-in calling timer from [00:00] to [59:59] * On-chip power-on reset and clear LCD * Uses 3.579545 MHz TV quartz crystal or ceramic resonator
*
Uses 32768 Hz crystal as RTC frequency base
* Packaged in 64-pin plastic QFP with RTC * Switchable 24-hour clock or 12-hour clock with p.m. mode by keypad * 0 or 9 dialing inhibition pin for PABX systems or long distance dialing lock out * On hook debounce: 150 mS in normal mode and 20 mS in lock mode * Off-hook delay 300 mS in lock mode (DP will keep low for 300 mS while off hook except the first
off hook after power on reset that DP will keep high for 100 mS then go low for 200 mS)
* First key-in delay: 300 mS in lock mode * Mixed dialing allowed

PIN DESCRIPTION
SYMBOL Row, Column Inputs PIN NO. 18-21, 13-17 I/O I FUNCTION The keyboard inputs may be used with either the standard 5 x 6 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. XT1, XT1 22, 23 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 finished. The crystal frequency deviation is 0.02%. T/P MUTE 8 O The T/P MUTE is a conventional CMOS N-channel open drain output. The output transistor is switched on low level during dialing sequence (both pulse and tone mode), one-key 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, flash break and hold functions, this pin will output an active high. It remains in a low state at all other times. 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:

HFI pin is pulled to VDD by internal resistor. Detailed timing diagrams are shown in Figure 4(a), 4(b). 11 O This pin is a CMOS N-channel open drain output. Flash key will cause DP to go active in either pulse mode or tone mode. In lock mode, the DP keeps low for 300 mS during off-hook delay time. 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 time. 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).

FUNCTION COM1 to COM4 are the common signal output terminal for the 1/4 duty LCD. SEG1 to SEG32 are the 16-digit segment signal outputs. A quartz crystal oscillator provides an RTC frequency time base of 32.768 KHz. Either VRTC1 should be connected to a 1.5V battery, and VRTC2 should be connected a capacitor 0.1 F to ground. Power input pins. Pulling mode pin to VSS places the dialer in tone mode. Pulling mode pin to VDD places the dialer in pulse mode (10 ppS, M/B = 1/2). Leaving mode pin floating places the dialer in pulse mode (10 ppS, M/B = 2/3).
