DESCRIPTION
The SC9302 series tone/pulse dialers are CMOS LSIs for the
telecommunication system. They are designed to meet various
dialing specifications through resistor options matrix.
The SC9302 series tone/pulse dialers are offered in four different
versions. They are SC9302X normal version, SC9302/F/G/H simple
version, SC9302XT key-tone version and SC9302XLT key-tone/lock
functions version. The SC9302X normal version provides the pin-
selected lock function; the SC9302XT version provides the key-tone
function; the SC9302XLT version provides both the key-tone function
and key board-operated IDD lock function. All of the above three
versions also supply the following functions: Hold-line, Hand-free and
LCD dialing number display interface, all of which are suitable for
feature phone applications. However, the SC9302F/G/H version is
simpler than the other three versions. It provides only a redialing
memory for a simple low-cost system application.

for key input detecting.
An inexpensive single contact 4x4 keyboard can be an input device.
Pressing a key connects a single column to a single row, and actuates
the system oscillator to result in a dialing signal output. If more than two
keys are pressed at the same time, no response can be brought about.
The key-in debounce time is 20ms. Refer to the keyboard table for
keyboard arrangement and to the functional description for dialing
specification selection.
The system oscillator consists of an inverter, a bias resistor and the
necessary load capacitor on chip. Connecting a standard 3.579545MHz
crystal or ceramic resonator to X1 and X2 terminals can implement the
oscillator function. The oscillator is turned off in the stand-by mode, and
is actuated whenever a keyboard entry is detected.

During the off-hook state, the pin also outputs the dialing pulse train in
pulse mode dialing. While in the tone mode, this pin is always high.
This is a three-state input/output pin, provided to the user for selecting a
dialing mode among Tone/20pps/10pps.

During the pulse mode dialing, switching this pin to the tone mode
changes the following entrance of digits to the tone mode. When the
chips are working in the tone mode, the switching from tone to the pulse
mode will be recognized.
This pin is active only when the chip transmits tone dialing signals.
Otherwise, it always outputs low. The pin outputs tone signals to drive
the external transmitter amplifier circuit. The load resistor should not be
less than 5kΩ.
This pin is a schmitt trigger input structure. Active low. Applying a
negative going pulse to this pin can toggle the HDO output once.
An external RC network is recommended to use for the input
debouncing. The pull-high resistance is 200kΩ typically.
The HDO is a CMOS output structure. Its output is toggle controlled by
a negative transition on

The 1C~4C and 1R~4Rmake up of a keyboard matrix. Together with a standard 4x4 keyboard, the
keyboard matrix is used for dialing entrance. In addition, the keyboard matrix provides resistor option for different
dialing specification selections. The keyboard arrangement for each of the SC9302 series are listed in KEYBOARD

3. DIALING SPECIFICATION SELECTION
By means of adding resistors across keyboard matrix
pins, various dialing specifications can be selected. The
allowable option resistor connections are shown right.
All the resistors are 330kΩ. The resistor option functions and the default specifications (without option resistors)
are listed below.

11. DOUT BCD CODE
When dialing, the corresponding 4-bit BCD codes are serially presented on DOUT from MSB to LSB. The data of
the DOUT is valid at the falling edge of the CLOCK pin. The following table lists the BCD codes corresponding to the
keyboard input.

12. LOCK FUNCTION
The function aims to detect locked dialing number to prevent a long distance call. The dialing output of the chip is
disabled if the first input key after on-off-hook is the locked number when the lock function is enabled. The lock
function selection is listed below.
The SC9302X version is the pin-selected type; on the other hand, the SC9302XLT is the key-board operated type.
However, the SC9302XT version does not support any lock function.

R Redial key. It executes the redialing as well as one-key redial function.
ST This key can store lock number with personal code in IDD lock operation.
R/P
These are dialing number input keys for both the pulse mode and the tone mode
operations.
This key executes the PT function and waits a T
the other hand, the */T key executes the * function in the tone mode.
Pressing this key can save the preceding dialing telephone numbers. The saved
number is redialed if it is pressed again. SA will also redial the saved number if it is the
first key depressed at the off-hook state. During the dialing signal transmission, the SA
key is inhibited.
The flash key can be selected as a digit or a control key by the option resistors
R

and is then followed by T
Pause key. The execution of the pause key pauses the output for the T
can be selected by R
Redial and pause function key. If it is pressed as the first key after off-hook, this key
executes the redial function. Otherwise, it works as the pause key.
