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
harmonic distortion
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.
