Note : PDP = Pocket Dialer Prevented
The EM91465 is a series of tone/pulse switchable dialers that is composed of T/P dialer and T/P dialer with
13 set memories. The EM91465 provide modern LCD driver's series data output port, which can display modern
function operating icons. The EM91465 series provide necessary functions of telephone set for application in
any environment, such as Pulse dialing, Tone (DTMF) dialing, Handfree dialing, keying tone ,and lock functions.
The lock function is designed to inhibit toll dialing operation. Beside this, ring detector and SDO (Serial Data
Output) functions are provided in advance version. Ring detector can prevent illegal dialing from pocket dialer.
The SDO is designed to drive LCD driver and voice synthesizer. In this application, the dialing numbers and
modern function operating icons can be displayed on LCD screen with LCD driver ( EM32100 or EM32117
). The EM91465 has a special I.P.P. detect function (Illegal Parallel Phone Detect) can prevent the illegal connect
external Phone. The I.P.P. will detect the illegal user. When illegal user pickup phone, the function will alarm
and send the alarm signal to the telephone line to interfer the illegal dialing.
• I.P.P. detect function prevents the illegal connect external phone.
• SDO function supports LCD driver and voice synthesizer to indicate dialing numbers and function operat
• Lock function provides conventionality key lock and password lock operations.
• Ring detector is designed to prevent illegal dialing from pocket dialer.
• Line hold function is designed for stopping conversation temporality.
• Tone/Pulse switchable.
• Adding resistor on keyboard scan pin that can select many telephone specifications, such as : Pulse rate,
• 13 set one touch or (3 set one touch and 10 set two touch) repertory memory, each one can hold data up to
• A 32-digit LNB (last number) redial memory.
• Keytone function provides rapidly keying recognition.
• Handfree function provides on-hook dialing and speakerphone application.
• Pause and P-T time are fixed to 3.6 seconds.
• Tone duration and inter-tone pause time are fixed to 98 ms.
• Using 3.579545 MHz crystal or ceramic resonator.
• Package forms: PDIP, skinny.
Wide operating voltage from 2.0 V to 5.5 V.
