Description
CMOS
IN/OUT
These pins form a 4´5 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~C5) remains low and the row group
(R1~R4) is set high for key input detection.
An inexpensive single contact 4´5 keyboard can be used as an input device.
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.
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. 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 the HKS and HFO/HDO
signals, control the dialer to connect or disconnect the telephone line.
PO outputs a low to break line when HKS is high (on-hook) and HFO/HDO is low.
PO outputs a high to make line when HKS is low (off-hook) or HFO is high or HDO
is high.
During the off-hook state, this 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, use for dialing mode selection, either Tone
mode or Pulse mode, 10pps/20pps
MODE=VDD: Pulse mode, 10pps
MODE=OPEN: Pulse mode, 20pps
MODE=VSS: Tone mode
During the 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 pulse mode will also be recognized.
DTMF
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.
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.

Pull-Low
This pin is a Schmitt trigger input structure. Active high. Applying a positive 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.
HFI
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 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.
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 the clock.

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

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. This function
is implemented on the HT9315xL. The HT9315x does
not support this function.

The flash key can be selected as a digit or as a control
key by the option resistors RK13 & RK14. Pressing the F
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 this key pauses the output for the TP duration. TP can be selected by RK21.
Function
· R
Redial key. Executes redialing as well as one-key redial function.
· ST
Store key. The execution of this key actuates the store
memory function with (or without) dialing output and it
can store lock number with personal code in IDD lock
operation. During the dialing signal transmission, the
ST key is inhibited.
Key definition
· 0,1,2,3,4,5,6,7,8,9 keys
These are dialing number input keys for both the pulse
mode and the tone mode operations.
· 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.
· */T
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.
· EM1~EM3
One-touch memory dialing key. For speed-calling
convenience, they provide memory dialing in either
pulse or tone mode.
· #
This is a dialing signal key for the tone mode only, no
response in the pulse mode.
· A
· SA
Auto key. When this key is pressed before pressing
any one of the digital keys (0~9) it executes the
two-touch memory function.
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.
