1-MEMORY/2-MEMORY TONE/PULSE DIALER
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 pinselected 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.

PIN DESCRIPTION
Pin Name I/O Internal Connection
SC9302 Series
Description
These pins construct a 4x4 keyboard matrix to perform the keyboard input detecting and dialing specification setting functions, when on-hook ( HKS =high) all the pins are set to high. While off-hook the column group ( C1 ~ C4 ) stays low and the row group ( R1 ~ R 4 ) is set to high for key input detecting.
C1 ~ C4
R1 ~ R 4
I/O
CMOS IN/OUT
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

I OSCILLATOR
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. The XMUTE is an NMOS open drain structure pulled to VSS during

HKS =VSS: Off-hook state ( PO =high). The chip is in the stand-by
mode and ready to receive the key input. (to be continued)

FUNCTION DESCRIPTIONS
1. KEYBOARD MATRIX
The C1 ~ C 4 and R1 ~ R 4 make 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 INFORMATION.

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.

13. KEY DEFINITION Key Name
0,1,2,3,4,5,6,7,8,9 numerical keys */T # operations.
SC9302 Series
Function
These are dialing number input keys for both the pulse mode and the tone mode
This key executes the P T function and waits a TP
T
duration in the pulse mode. On
the other hand, the */T key executes the * function in the tone mode. This is a dialing signal key for the tone mode only, no response in the pulse mode. Pressing this key can save the preceding dialing telephone numbers. The saved
SA
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 RK13&RK14. Pressing the flash key will force the PO pin to be "low" for the TF duration and is then followed by TFP(sec). TF can also be selected by RK13, RK14.
F
P R ST R/P
Pause key. The execution of the pause key pauses the output for the TP duration. TP can be selected by RK21. Redial key. It executes the redialing as well as one-key redial function. This key can store lock number with personal code in IDD lock operation. 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.
