Semiconductors /G3 SC9302 Series /G3 HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD /G3 Rev: 2.0 2001-11-01/G3 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 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. SDIP-24 /G3

Semiconductors /G3 SC9302 Series /G3 HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD /G3 Rev: 2.0 2001-11-01/G3 PIN DESCRIPTION Pin Name I/O Internal Connection 1C ~ 4C 1R ~ 4R I/O CMOS IN/OUT 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 ( 1C ~ 4C ) stays low and the row group (1R ~ 4R ) is set to high 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. X1 I X2 O OSCILLATOR 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. XMUTE O NMOS OUT The XMUTE is an NMOS open drain structure pulled to VSS during dialing signal transmitting. Otherwise, it is an open circuit. The XMUTE is used to mute the speech circuit when transmitting the dial signal. HKS I CMOS IN This pin is used to monitor the status of the hook-switch and its combination with HFI/HDI can control the PO pin output to make or break the line. HKS =VDD : On-hook state (PO =low). Except HFI/HDI (hand-free / hold-line control input), other functions are all disabled. 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)

Semiconductors /G3 SC9302 Series /G3 HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD /G3 Rev: 2.0 2001-11-01/G3 (continued) PO O CMOS OUT This pin is a CMOS output structure, it receives HKS and HFO/HDO signals to control the dialer so as to connect or disconnect the telephone line. PO outputs low to break line when HKS is high (on-hook) and HFO/HDO is low. PO outputs high to make line when HKS is low (off- hook) or HFO is high or HDO is high. 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. MODE I/O CMOS IN/OUT This is a three-state input/output pin, provided to the user for selecting a dialing mode among Tone/20pps/10pps. MODE=V DD: Pulse mode, 10pps. MODE=OPEN: Pulse mode, 20pps. MODE=V SS: Tone mode. 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. DTMF O CMOS OUT 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. HDI I CMOS IN Pull-High 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. HDO O CMOS OUT The HDO is a CMOS output structure. Its output is toggle controlled by a negative transition on HDI . When HDO is toggled to high, PO keeps high to hold the line. The hold function can be released by setting HFO high or by an on-off hook operation or by another HDI input. The HDO pin can directly drive the melody generator to produce hold-line background melody. Refer to the functional description for the hold-line function. KT O CMOS OUT Key-tone output pin. It outputs 1.2kHz tone carrier when any key is pressed in the pulse mode or when the function keys are pressed in the tone mode. (to be continued)

Semiconductors /G3 SC9302 Series /G3 HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD /G3 Rev: 2.0 2001-11-01/G3 (continued) HFI I CMOS IN Pull-Low This pin is a schmitt trigger input structure. Active high. Applying a positive going pulse to HFI can toggle the HFO once and hence control the hand-free function. The pull-low resistance of HFI is 200KΩ typically. An external RC network is recommended to use for the input debouncing. HFO O CMOS OUT The HFO is a CMOS output structure. Its output is toggle controlled by a positive transition on HFI pin. When HFO is high, the hand-free function is enabled and PO outputs high to connect the line. The hand-free function can be released by setting HDO high or by an on-off-hook operation or by another HFI input. Refer to the functional description for the hand-free functional operation. LOCK I/O CMOS IN/OUT This is a three-state input/output pin, provided to the user for controlling the long distance call function with a lock-switch. LOCK=OPEN: Normal dialing (no lock). LOCK=V DD : “0,9” is inhibited for use as the first key input. LOCK=VSS : “0” is inhibited for use as the first key input. DOUT O NMOS OUT This is an NMOS open drain output pin. It outputs the BCD code of the dialing digits to the LCD driver chip (SC16XX series) or µC for dialing number display. Refer to the functional description for the detailed timing. CLOCK O NMOS OUT NMOS open drain output. When dialing, it outputs a series of pulse train for the DOUT data synchronization. The DOUT data is valid at the falling edge of clock. VDD I -- Positive power supply, 2.0V~5.5V for normal operation. VSS I -- Negative power supply. FUNCTION DESCRIPTIONS 1. KEYBOARD MATRIX The 1C ~ 4C and 1R ~ 4R 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.

Semiconductors /G3 SC9302 Series /G3 HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD /G3 Rev: 2.0 2001-11-01/G3 13. KEY DEFINITION Key Name Function numerical keys These are dialing number input keys for both the pulse mode and the tone mode operations. */T This key executes the P/barb2rightT function and waits a TP/barb2rightT 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. SA 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. F The flash key can be selected as a digit or a control key by the option resistors R K13&R K14. 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. P Pause key. The execution of the pause key pauses the output for the TP duration. TP can be selected by RK21. 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 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.
