Pin Description
Pin Name
C1~C4
R1~R4
I/O
Description
These pins form a 4´4 keyboard matrix which can perform keyboard input detection and dialing specification setting functions. When on-hook (HKS=high) all the
pins are set high. While off-hook the column group (C1~C4) remains low and the
row group (R1~R4) is set high for key input detection.
An inexpensive single contact 4´4 keyboard can be used as an input device.
I/O CMOS IN/OUT
Pressing a key connects a single column to a single row, and actuates the system
oscillator that results in a dialing signal output. If more than two keys are pressed at
the same time, no response occurs. The key-in debounce time is 20ms. Refer to
the keyboard information for keyboard arrangement and to the functional description for dialing specification selection.

I

O
XMUTE
O
HKS
Internal
Connection
I
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
OSCILLATOR resonator to the X1 and X2 terminals can implement the oscillator function. The
oscillator is turned off in the standby mode, and is actuated whenever a keyboard entry is detected.
NMOS OUT
XMUTE is an NMOS open drain structure pulled to VSS during dialing signal
transmission. Otherwise, it is an open circuit. The XMUTE is used to mute the
speech circuit when transmitting the dial signal.
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 for 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 standby mode and
ready to receive the key input.
CMOS OUT
This pin is a CMOS output structure, which by receiving HKS and HFO/HDO
signals, control the dialer to connect or disconnect the telephone line.
PO outputs a low to break the line when HKS is high (on-hook) and HFO/HDO
is low. PO outputs a high to make the 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.
PO
O
MODE
This is a three-state input/output pin, used for dialing mode selection whether
Tone mode or Pulse mode; 10pps/20pps.
MODE=VDD: Pulse mode, 10pps
MODE=OPEN: Pulse mode, 20pps
I/O CMOS IN/OUT
MODE=VSS: Tone mode
During pulse mode dialing, switching this pin to the tone mode changes the
subsequent digit entry to tone mode. When the chips are in tone mode, switching to the pulse mode will also be recognized.

Description
O
CMOS OUT
This pin is active only when the chip transmits tone dialing signals. Otherwise, it
always outputs a low. The pin outputs tone signals to drive the external transmitter amplifier circuit. The load resistor should not be less than 5kW.
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 for input debouncing. The Pull-high
resistance is 200kW typ.
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 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. Refer to the functional description for the
hold-line function.
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 200kW typ.
An external RC network is recommended for input debouncing.
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 a 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
This is a three-state input/output pin, used for controlling long distance call
function with a lock-switch.
I/O CMOS IN/OUT LOCK=OPEN: Normal dialing (no lock)
LOCK=VDD: ²0, 9² is inhibited for use as the first key input
LOCK=VSS: ²0² is inhibited for use as the first key input
DOUT
O
NMOS OUT
NMOS open drain output pin. It outputs the BCD code of the dialing digits to the
LCD driver chip (HT16XX series) or MCU 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 trains for
DOUT data synchronization. DOUT data is valid at the falling edge of clock.

· F
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 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 ²low² for the tF duration
and is then followed by tFP (sec). tF can also be selected
by RK13, RK14.
· HT9302x version
LOCK Pin
· P
Pause key. The execution of the pause key pauses
the output for the tP duration. tP can be selected by
RK21.
Function
OPEN
Normal dialing (no lock)
VDD
²0, 9² is inhibited
VSS

· R
Redial key. Executes redialing as well as one-key redial function.
Key definition
· ST
· 0,1,2,3,4,5,6,7,8,9 keys
This key can store lock number with personal code in
IDD lock operation.
These are dialing number input keys for both the pulse
mode and the tone mode operations.
· R/P
· */T
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.
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.
· 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 pressed at the off-hook state. During
the dialing signal transmission, the SA key is inhibited.
