PIN DESCRIPTIONS
Symbol
Function
ROW1~ROW4
Keyboard scan pins of row group. In idle state (HKS is “High” and HFO is “Low”),
these pins stay “High impedance” level to prevent power consumption. Otherwise,
these pins switch to “High” level for detecting keyboard entry. These pins will output
600 Hz signal while keyboard is scanning.
COL1~COL3 and COL5
COL4/KT
Keyboard scan pins of column group. In idle state, these pins stay “High impedance”
level. Otherwise these pins switch to “Low” level for detecting keyboard entry. These
pins will output 600 Hz signal while keyboard is scanning.
The fourth column group pin of the keyboard that also provides the keytone output
. Normally, this pin stays “Low” level for detecting keyboard entry. After a valid
keyboard entry, this pin will output keying confirmation tone that is 600 Hz signal and
30 ms duration. While DTMF output, the key tone will be disabled. To prevent signal
interference, while DTMF issue, it will disable key tone output except function key.
Oscillator input and output pins. A 3.579545 MHz crystal or ceramic resonator must
be crossed connection to XIN and XOUT pins which generate system clock.
The Tone/Pulse MUTE signal output pin that is NMOS open-drain output structure.
This pin will switch to “Low” level during Tone/Pulse dialing.
XIN and XOUT
XMUTE
Otherwise, this pin stays “High impedance” level.
V
DD and VSS
Positive and negative power supply input pins. Recommended operating voltage from
2.0Vdc to 5.5Vdc.
HFI
Handfree inputs pin which accepts falling edge signal to turn “on” or turn “off”
handfree function. This pin is hysteresis input structure and built-in pull up resistor
(typically 200 Kohms).
HFO
DTMF
Handfree outputs pin that is designed to control telephone line for on-hook dialing or
control speakerphone circuit for handfree conversation. When handfree function is
executed, this pin will switch to“High”. Otherwise, this pin stays “Low” level.
The DTMF (Dual Tone Multi-Frequency) output pin. Normally, this pin stays“Low”
level. In Tone dialing mode, this pin will output DTMF signal that is corresponding
to keyboard 0..9, * and # keys.
HKS
Control signal inputs pin that is corresponding hook switch status. When handset was
left from cradle, this pin must be connected to “Low” level to operate all functions.
Otherwise, this pin must be connected to “High” level to disable all function and
prevent power consumption.
PO
Pulse signal outputs pin that is NMOS open-drain output structure. Normally, this pin
stays “High impedance” level. In Pulse dialing mode and keypad was entry. This pin
will output pulse trains signal that is corresponding to keyboard 0 .. 9 keys.
Pulse signal outputs pin that is CMOS inverter output structure. Normally, this pin
stays “Low” level. During pulse signal dialing or flash function executing, this pin will
switch to “High” level to control the external circuit.
SDO function output that is NMOS open-drain structure. When there is a valid entry
on keyboard, this pin will output a serial data. This serial data is designed to drive LCD
driver to display dialing number on LCD screen or drive voice synthesizer to announce
dialing number to speaker.

Normal dialing
Directly keying digital key on keyboard which number can be dialing output and stored in LNB memory
automatically. Operating procedure described as follow :
• To select Pulse or Tone mode.
• Off-hook or turn on HF function.
• Keying d1, d2, .. , dn. The “d” expressed digital keypad that included 1~9, *, 0, #, P, and P→T keys. The “n”
expressed unlimited.
• The numbers d1, d2, .. , dn will be dialed out in Pulse or Tone mode as selection.
LNB redial memory
Storing:
In normal dialing mode, every digital key was entry which number will be stored in LNB memory
automatically. If entry digits are more than 32 digits, the redial function of LNB memory will be disabled.
Otherwise, these numbers stored in LNB memory can be redial output.
Redialing:
After normal dialing, directly keying F key (or On-Off hook once) and keying RD key on keyboard. The
numbers that are stored into LNB memory will be dialed output.
SAVE redial memory
The SAVE meomry is designed in EM91203 series to support 32 digits capacity buffer for second redial,
pager, Memory and other system applications.
* This specification are subject to be changed without notice.

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.
* This specification are subject to be changed without notice.

TONE/PULSE SWITCHABLE DIALER WITH LCD INTERFACE
• To select Pulse or Tone mode.
• Off-hook (or turn on HF function), push d1, d2, .. , dn, RD/P, k1, k2, .. , kn . These numbers will be dialed
out as following sequence:
d1, d2, .. , dn, Tp, k1, k2, .. , kn.
Pulse to Tone (*/T or P-T) key operation
The Pulse to Tone (*/T or P-T) key is designed to support toll dialing (long distance call) or PABX system
operation. The "*/T (or P-T)" key can be stored in memory and it will occupy one digital position.
• To select Pulse mode.
• Off-hook (or turn on HF function), push d1, d2, .. , dn, */T, (or P-T) k1, k2, .. , kn. These numbers will be dialed
out as following sequence:
d1, d2, .. , dn, Tpt, k1, k2, .. , kn.
(pulse mode)
(tone mode)
Flash (F) key operation
The Flash (F) key is designed to break telephone line temporarily. After F key is depressed, this dialer will send
a flash signal to break line 600 ms, 300 ms, 100 ms or 80 ms as ROW3 and ROW4 selection.
Handfree (HF) function
The handfree function is designed to support on-hook dialing and loudspeaker application which can be turn “on”
or “off” with falling edge signal from HFI pin. During handfree function is executed, the HFO pin is switched
to “high”. Otherwise the HFO pin stays “low” level.

SDO (Serial Data Output) function
The SDO is serial data output which format is same as UART protocol. SDO function is designed to drive LCD
driver and voice synthesizer. So the dialing numbers can be display on LCD screen with EM32100 (or EM32116
). The SDO signal consists of two start bits, six data bits and two stop bits. Each bit time is about 3.9 ms (256 Hz)
and output sequences are following by start bits, data bits (LSB to MSB) and stop bits.
