W91810N SERIES 23-MEMORY TONE/PULSE DIALER WITH HANDFREE, LOCK AND HOLD FUNCTIONS
GENERAL DESCRIPTION
The W91810N is a series of tone/pulse switchable telephone dialers with 23 memory, keytone, hold, lock, mute, volume control and handfree dialing control features. These chips are fabricated using Winbond's high-performance CMOS technology and thus offer good performance in low-voltage, lowpower operations.

PIN DESCRIPTION
SYMBOL ColumnRow Inputs 22-PIN 1-5 & 18-22 24-PIN 1-5 & 20-24 28-PIN 1-6 & 23-28 I/O I FUNCTION The keyboard input is compatible with a standard 6 x 6 or 7 x 7 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 a single tone. XT 9 9 10 I A built-in inverter together with an inexpensive 3.579545 MHz crystal supplies the oscillator. The oscillator stops when there is no keypad input. The crystal frequency deviation is 0.02%. Crystal oscillator output pin. The T/P MUTE is a conventional CMOS Nchannel open drain output. The output transistor turns on with a low level during a dialing sequence (both pulse and tone mode). Otherwise, it is off. K MUTE 17 19 22 O The K MUTE is a conventional CMOS N-channel open drain output. Toggle action speech mute control pin by MUTE key. MODE 15 17 20 I Connecting the mode pin to VSS places the dialer in tone mode. Connecting the mode pin to VDD places the dialer in pulse mode with an M/B ratio of 40:60. Leaving the mode pin floating places the dialer in pulse mode with an M/B ratio of 33.3:66.7.

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 VDD by internal resistor.

FUNCTION 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. 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. The function of the LOCK pin is shown below:

The H/P MUTE is a conventional inverter output. During pulse dialing, flash break or hold period, this output is active high; otherwise, it remains in low state.

is pressed, the dialer will execute a flash break time of 600 mS (F1), 300 mS
(F2), 73 mS (F3) or 100 mS (F4) and a pause time of 1.0 second, after which the next digit is dialed out. 2. The flash key has the first priority of the keyboard function only one flash key will be released to the user. 3. When the flash key is key in, the system will return to the initial state after the flash pause time is finished. 4. The flash function timing diagram is shown in Figure 8.
