GENERAL DESCRIPTION
The EM91203 is a series of tone/pulse switchable dialers that is composed of T/P dialer and T/P dialer with
3 sets memories. The EM91203 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 ).
FEATURES
• 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, Pause time, P-T wait time and keyboard type.
• SDO function supports LCD driver and voice synthesizer to indicate dialing numbers.
• Handfree function provides on-hook dialing and speakerphone application.
• 3-set one touch repertory memory, each one can store data up to 16 digits.
• 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.

EM91203 SERIES
TONE/PULSE SWITCHABLE DIALER WITH LCD INTERFACE
Storing : EM91203 series support two operating methods to store numbers into SAVE redial memory.
Method 1
• To select Pulse or Tone mode.
• Off-hook (or turn on HF function), push d1, d2, .. , dn. The numbers d1, d2, .. , dn will be dialed out in Pulse
or Tone mode as selection.
• After dn had been dialed out and push [ST], Save key. If the keying numbers are more than 32 digits that
content of SAVE memory can not be updated. Otherwise, these numbers will be stored into SAVE memory.
In the [] key allows to be omitted.
Method 2
Off-hook (or turn on HF function), push ST, d1, d2, .. , dn, [ST], Save. If the keying numbers are not over 32
digits, the numbers d1, d2, .. , dn will be stored in SAVE redial memory automatically.
Dialing :
• To select Pulse or Tone mode.
• Off-hook (or turn on HF function), push Save key. The numbers stored in SAVE memory will be dialed out
in Pulse or Tone mode as selection.
Repertory memory
The EM91203 series incorporated several sets repertory memory and each one can store number up to 16 digits.
As in memory storing, if stored numbers are more than 16 digits that only the previous 16 digits can be stored
into specific memory. Otherwise, these numbers can be stored entirely. After memory dialed out, the content
of LNB is keeping to current data.
Storing of 3 sets memory
Direct (one-touch) operation
Off-hook (or turn on HF function), push ST, d1, d2, .. , dn [ST], EMn. The numbers d1, d2, .. , dn will be stored
into memory location “EMn”. The “EMn” expressed emergency memory EM1 to EM3.
Dialing (after memory dialed out, the content of LNB is keeping to current data)
Direct (one-touch) memory operation
• To select Pulse or Tone mode.
• Off-hook (or Turn on HF function), push EMn key. The numbers that are stored in direct memory location
EMn will be dialed out in Pulse or Tone mode as selection. The “n” expressed digital number from 1~3 decided
by dialers’ memory sets.
Pause (P) key operation
The Pause (P) key is designed to support pause operation in dialing duration. “P” key can be stored in memory
and it will occupy one digital position.
