W91560N SERIES 3-MEMORY TONE/PULSE DIALER WITH SAVE, KEYTONE, LOCK AND HANDFREE FUNCTIONS
GENERAL DESCRIPTION
The W91560N series are tone/pulse switchable telephone dialers with three memories, keytone or lock, and handfree dialing control. These chips are fabricated using Winbond's high-performance CMOS technology and thus offer good performance in low-voltage, low-power operations.

PIN DESCRIPTION
SYMBOL ColumnRow Inputs 18-PIN 1-4 & 15-18 20-PIN 1-4 & 17-20 I/O I FUNCTION The keyboard input is compatible with a standard 5 x 5 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 function. Activation of two or more buttons will result in no response except for single tone. XT 7 7 I A built-in inverter provides oscillation with an inexpensive 3.579545 MHz crystal. The oscillator ceases when a keypad input is not sensed. The crystal frequency deviation is 0.02%. Crystal oscillator output pin. 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). Otherwise, it is switched off. MODE 13 15 I Pulling mode pin to VSS places dialer in tone mode. Pulling mode pin to VDD places dialer in pulse mode with M/B ratio of 40:60 (10 ppS, except for W91560BN, which is 20 ppS). Leaving mode pin floating places dialer in pulse mode with M/B ratio of 33.3:66.7 (10 ppS, except for W91560BN, which is 20 ppS). HKS 10 12 I 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. KT 5

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.
