The EM91215 is a series of tone/pulse switchable dialers that is composed of T/P dialer and T/P dialer with 13
set memories. The EM91215 series provides necessary functions of telephone set for application in any
environment, such as Pulse dialing, Tone (DTMF) dialing, Handfree dialing, keying tone , mute and pulse mute
functions. Beside this, SDO (Serial Data Output) functions is provided in advance version that is designed to
drive LCD driver and voice synthesizer. In this application, the dialing numbers can be displayed on LCD screen
with EM32100 ( or EM32116 ).
• Tone/Pulse switchable.
• Adding resistor on keyboard scan pin that can select many telephone specifications, such as : Pulse rate,
• SDO function supports LCD driver and voice synthesizer to indicate dialing numbers.
• Handfree function provides on-hook dialing and speakerphone application.
• 13 set one touch or (3 set one touch and 10 set two touch) repertory memory, each one can store data up to
• A 32-digit LNB (last number) redial memory.
• A 32-digit SAVE redial memory.
• Keytone function provides rapidly keying recognition.
• Pulse mute function supports pulse dialing application.
• Using 3.579545 MHz crystal or ceramic resonator.
• Package forms: PDIP , skinny.
Wide operating voltage from 2.0 V to 5.5 V.
