PRELIMINARY
Multi-Feature Phone LSI With LCD Driver
Features
4-bit CMOS
n The NT93403-05X is a multi-feature tone/pulse dialer
based on a CMOS 4-bit single chip microcomputer
with 5120 X 10 bit ROM and 1204 X 4 bit RAM
capacity
n Built-in LCD driver and direct interface with 16-
digit LCD display
Dialing
n Dialing parameters are set by external diodes and
the SELECT pin
n Built-in high-precision dual-tone multi-frequency
(DTMF) generator and on-chip pulse dialer
n Switchable tone/pulse dialing
n Dialing speeds of 10 or 20 pps and Make/Break Ratio
of 40/60 or 33/67
n Normal or Sweden/Denmark modes for number of
pulses selectable
n Minimum DTMFsignal duration/separation guaranteed
n Chain dialing
n Manual dialing will execute as many digits as entered
n Redial function (up to 48 digits)
Long distance control
n Three long distance control functions are available:
(1) Key Lock: The chip will detect the key lock status
(2) Pass Code: The chip will check pass code.
(pass code replaces key)
(3) Key and pass code
n With the diode setting, three defaults can be chosen:
0,168
n Three-digit restriction codes are user-programmable
n For restriction dialing, "0" and "168" can be restricted
simultaneously
n Complete and strict restriction dialing function. For
example, "pause" key + "0" key will not dial out for "0"
restriction dialing
n "SOS" key is provided for forgotten pass codes,
which when depressed, automatically resets to 000
Memory
n 13 24-digit memory locations: 3 direct and 20 indirect
memories
n 3 single button dialing memories
n One-touch auto-dialing and abbreviated dialing
n "MEM"key used for abbreviated dialing
n "EM1", "EM2" and "EM3" memory locations are
provided
Pause, Flash, Hold, Mute, P/T
n Pause time programmable from 1 to 5 seconds
(1 second resolution) by key entry
n Flash time programmable from 90, 100 msec to 900
msec (100 msec resolution) by key entry
n Manual HOLD key controls HOLDOUT signal. Hold
mode can be released by HOLDIN input pin
n HOLD LCD indicator (blinking) and HOLDOUT for
music during hold
n Manual MUTE key controls XMUTE signal
n Pulse to tone key function
Other Features
n 5 sets of the last dialed phone numbers (up to 24
digits) and dialing time (mm-ss)
n LCD self testing function
n Calendar and real time clock display with 12-hour
format and AM/PM indicator
n Key-in tone output for valid key data
n Error display and error beep sounds when sequence
is entered incorrectly
n Speaker phone control output and LED control pin
are provided
n Reset pin provided
n 5 X 7 matrix keypad interface
n Operating Voltage Range: 2.5V - 5.5V
