SC91310 Series
TONE / PULSE DIALER WITH
REDIAL FUNCTION
DESCRIPTION
The SC91310 series are monolithic ICs that provide the necessary
signals for either pulse or tone dialing. The SC91310 series feature a
redial memory.
FEATURES
*DTMF / Pulse switchable dialer
*32 digits for redial memory
*pulse-to-tone (P→T) keypad for long distance call operation
*Break / Make ratio is selectable by pin option
*Uses 4x4 keyboard
DIP-18
*Easy operation with redial, flash, pause, and P→T keypads
*Flash, pause, P→T (pulse-to tone) can be stored as a digit in
memory
*Minimum tone output duration:100ms
*minimum intertone pause: 100ms
*On-chip power-on reset
*Uses 3.579545 MHz crystal or ceramic resonator
*Packaged in 18-pin plastic DIP

Note: 1. Crystal parameters suggested for proper operation are Rs<100Ω, Lm=96mH, Cm=0.02pF, Cn=5pF,
Ci=18pF, Fosc.=3.579545MHz±0.02%.
2. Crystal oscillator accuracy directly affects these times.

De sc ription
The keyboard input may be from either the standard 4x4 keyboard or an
inexpensive single contact (form A) keyboard. Electronic input from a µC can
also be used. A valid key entry is defined as a single row being connected to a
single column.

The T/P
is a conventional CMOS N-channel open drain output. The

output transistor is switched on during pulse and tone mode dialing sequence
and flash break. Otherwise, it is switched off.
Pulling mode pin to Vss places the dialer in tone mode. Pulling mode pin to VDD
places the dialer in pulse mode (10 pps). Leaving mode pin floating places the
dialer in pulse mode (20 pps).

2. NORMAL DIALING
OFF HOOK , D1 , D2 , … , Dn
1) D1, D2, …, Dn will be dialed out.
2) Dialing length is unlimited, but redial is inhibited if length oversteps 32 digits.
3.REDIALING
OFF HOOK , D1 , D2 , … , Dn BUSY , COME ON HOOK , OFF HOOK , R/P
The R/P key can execute redial function only as the first key-in after off-hook; otherwise, it will execute pause
function.
4. ACCESS PAUSE
OFF HOOK , D1 , D2 , R/P , D3 , …, Dn
1) The pause function can be stored in memory.
2) The pause function is executed in normal dialing or memory dialing.
3) The pause function timing diagram is shown in Figure 3.
5. PULSE-TO-TONE (PÆT)
OFF HOOK , D1 , D2 , …, Dn , PÆT , D1’ , D2’ , …, Dn’
1) If the mode switch is set to pulse mode, then the output signal will be:
D1, D2,…, Dn, Pause, D1’, D2’, …, Dn’

(Pause) (Tone)
3) The dialer remains in tone mode when the digits have been dialed out and can be reset to pulse mode only
by going on-hook.
4) The PÆT function timing diagram is shown in Figure 4.
6. FLASH
OFF HOOK , F
1) Flash key can be stored as a digit in memory.
2) The system will return to the initial state after the break time is finished.
3) The flash function timing diagram is shown in Figure 5.
