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
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.
