EM91450 SERIES

TONE/PULSE DIALER WITH LCD INTERFACE

AND I.P.P. DETECT FUNCTION

GENERAL DESCRIPTION

The EM91450 is a series of tone/pulse switchable dialers that is composed of T/P dialer. The EM91465 provide

modern LCD driver's series data output port, which can display modern function operating icons. The

EM91450 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 EM91450 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.

FEATURES

• 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-

ing icons.

• 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.

• Wide operating voltage from 2.0 V to 5.5 V.

• Low operating current, 0.15 mA (Pulse) and 0.3 mA (Tone) typically.

• Adding resistor on keyboard scan pin that can select many telephone specifications, such as : Pulse rate,

M/B ratio, Flash time, lock dialing functions.

• 13 set one touch or (3 set one touch and 10 set two touch) repertory memory, each one can hold data up to

16 digits.

• 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.
