General Description
The NT91315XL series are single-chip silicon gate
CMOS integrated circuits with on-chip oscillators to be
used with a 3.58 MHz crystal or ceramic resonator. They
provide dialing pulse (DP) or dual tone multi-frequency
(DTMF) dialing. A 24-key (5x5-1) matrix keyboard is
used for either DP or DTMF mode. In on-chip RAM, up to

n Hands-Free control function with debouncing (BL, CL
& DL version)
n Hold function with debouncing (CL & DL version)
n Key-tone output for dialing access (DL version)
n One-key redial (DL version)
n Flash time 600ms, 300ms, 100ms (DL version)
n Power-up reset circuit provided
n Key release debouncing
n 32-step synthetic tone output for low DTMF output

n 16/18/20/22-pin packages
32 digits can be saved for both redial and save functions,
and up to 16 digits can be saved for 3 direct emergency
and 10 indirect dialing memory banks. In DTMF mode, a
small minimum tone duration and minimum inter-tone
pause allows for rapid dialing. Maximum tone duration
depends on the key depression time in manual dialing.

4. Chain Dialing
a. Off Hook D1 . . . Dk Mi (i = 1, 2, 3)
A/L Dm ( Dm = 0 - 9 ) Dk+1 . . . Dn .
It first dials out D1 . . . Dk , then the digits of
Mi , then the digits of indirect memory Dm ,
and finally Dk+1 . . . Dn .
b. Off Hook R/P R/P D1 . . . Dn
(i = 1, 2, 3)
Mi
Dials out the digits in redial memory, pauses for
2.2/3.6 sec, then dials D1 . . . Dn , and
finally the digits in Mi . The redial memory is
unchanged.
Note:
Memory keys can be accepted at any time during chain
dialing, whether or not the dialing process is completed.
5. Mix Dialing
Only PULSE mode to TONE mode is switchable. This
is achieved by either changing the MODE IN state, or
by depressing the */T key in PULSE mode. TONE
mode to PULSE mode switching is not allowed.
