TECHNICAL DATA
Tone/Pulse Dialer
High-Performance Silicon-Gate CMOS
IL91210E
The IL91210E is a single-chip, silicon gate, CMOS integrated circuit
with an on-chip oscillator for a 3.58 MHz crystal or ceramic resonator. It
provides dialing pulse (DP) or dual tone multi-frequency (DTMF)
dialing. A standard 4x4 matrix keyboard can be used to support either DP
or DTMF modes. Up to 32 digits can be saved in the on-chip RAM for
reading. In the DTMF mode, minimum tone duration and minimum
intertone pause are provided for rapid dialing. Maximum tone duration is
dependent upon the key depression time in manual dialing.
• One touch redial operation
• Tone/Pulse switchable
• 32-digit capacity for redialing
• Automatic mixed redialing (last number redial) of pulse to DTMF
with multiple automatic access pauses
ORDERING INFORMATION
IL91210EN
TA = -20° to 70° C
• PABX auto-pause is 2.2 second
• DTMF Timing:
Manual dialing: minimum duration for bursts and pauses
Redialing: calibrated timing
• Wide operating voltage range: 2 V to 5.5 V
• Digits dialed manually after redialing are cascadable and stored as additional digits for the next redialing
• Uses inexpensive ceramic resonator (3.58 MHz)
• Built-in power up reset circuit
www.DataSheet4U.com• Four extra function keys: flash, pause, redial and DP or DTMF mixed dialing
• Four-by-four (or 2 of 8) keyboard can be used
• Low standby current
• Dial Pulse Rate: 10 pps

b. Off Hook D1 . . . Dn */T Dn+1 Pulse Mode
Dn+m DTMF Mode
Pulse mode is initially defined with the mode
selection pin, MODE SELECT, equal to VCC. At this
time, the mode can be switched to DTMF by
pressing the */T key. DTMF mode will begin as
soon as the last pulse has been transmitted. In this
mode, Dn+1 through Dn+m are sent through the
TONE OUT pin as DTMF signals. If a P key entry
is contained in the series of digits before or after the
*/T entry, or the MODE SELECT switch is
depressed, 2.2 second pause will be added to the
automatically inserted pause time, which is also
2.2 seconds. Both of the above switching modes can
store as many as 31 digits in the redial memory.
6. One-Key redialing
Off Hook D1
......
Dn RD
If the dialing of D1 to Dn is completed, pressing RD
will cause the pulse dialing pin to go low for
2.2 seconds of break time and an 824 ms pause will
automatically be added. Otherwise, the pressing of
the redial key will be ignored.
7. Flash dialing
Off Hook F D1 . . . . . . Dn
The flash keys emulate quick On-Off Hook
operations. Pressing the flash keys, F1 or F2, will
cause a break of 96 ms or 640 ms on the DP output
pin. Then, it will pause for 824 ms and continue
dialing the digits, D1 to Dn . These digits are then
stored in the redial memory. Each time the flash key
is pressed, the redial memory will be cleared to store
a new entry. In addition, the MODE SELECT status
will be checked again for the setting of the
Tone/Pulse dialing mode.
Similarly, to make sure that the IC is working
properly, new flash key inputs will be ignored as
long as the digits that were dialed have not finished.
