W91530N SERIES 13-MEMORY TONE/PULSE DIALER WITH SAVE, KEYTONE, LOCK, AND HANDFREE FUNCTIONS GENERAL DESCRIPTION The W91530N series are tone/pulse switchable telephone dialers with 13 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.

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 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 (10 ppS) with M/B ratio of 40:60 (W91532/532AN is 20 ppS). Leaving mode pin floating places dialer in pulse mode (10 ppS) with M/B ratio of 33.3:66.7 (W91532/532AN 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 5 O (except (except W91531LN) W91531ALN) XT T/P MUTE 8 9 8 9 O O 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. -3- Publication Release Date: May 1997 Revision A3 W91530N SERIES Pin Description, continued SYMBOL LOCK 18-PIN 5 (only for W91531LN) 20-PIN 5 (only for W91531ALN) I/O I FUNCTION 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: LOCK PIN VDD Floating VSS FUNCTION "0", "9" dialing inhibited Normal dialing mode "0" dialing inhibited DP / C5 11 13 O N-channel open drain dialing pulse output. Flash key will cause DP to be active in either tone mode or pulse mode. In lock mode, the DP remains low for 300 mS during offhook delay time. The timing diagram for pulse mode is shown in Figure 1(a, b, c, d). During pulse dialing, this pin remains in low state regardless of keypad input. In tone mode, it will output a dual or single tone. A detailed timing diagram for tone mode is shown in Figure 2(a, b, c, d).
