SC91415
T/P SWITCHABLE DIALER WITH LCD INTERFACE AND DUAL-TONE MELODY
DESCRIPTION
The SC91415 is a series of tone/pulse switchable dialers that is
composed of T/P dialer and T/P dialer with 13 set memories. The
SC91415 series provide necessary functions of telephone set for
application in any environment, such as Pulse dialing, Tone (DTMF)
dialing, Handfree dialing, keying tone and lock functions. The lock
function is designed to inhibit toll dialing operation. Beside this, melody
generator, ring detector and SDO (Serial Data Output) functions are
provided in advance version. Melody generator will output dual-tone
music in line hold duration. Ring detector can prevent illegal dialing from
pocket dialer. The SDO is designed to drive LCD driver and voice
synthesizer.
FEATURES
ORDERING INFORMATION
* Tone/Pulse switchable
* Wide operating voltage from 2.0 V to 5.5 V

* Adding resistor on keyboard scan pin that can select many tele-
phone specifications, such as: Pulse rate, M/B ratio, Flash time, lock
dialing functions.
* Lock function provides conventionality key lock and password lock
operations

The dummy number “3”is not detected by the centered office or PABX ,but the following numbers “0”,1,2,3...
long distance call can be dialed out normally since the leading number “3”is not the Lock-number defined in
SC91415 series. To prevent the unavoidable long distance call, then SC91415 inhibits the key entry during Tdly.

G) Music on Hold
SC91415 series built-in a melody generator to generate dual-tone music on DTMF output pin. The music is
designed for telephone line at line holding.
H) SDO (Serial Data Output) function
The SDO is serial data output which format is same as UART protocol. SDO function is designed to drive LCD
driver and voice synthesizer. So the dialing numbers can be display on LCD screen with SC32100 (or SC32116).
The SDO signal consists of two start bits, six data bits and two stop bits. Each bit time is about 3.9 ms (256 Hz)
and output sequences are following by start bits, data bits (LSB to MSB) and stop bits.
