Description

C1~C5
R1~R4

I/O

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 os-
cillator 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 key-
board information for keyboard arrangement and to the functional description for dial-
ing specification selection.

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 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.

XMUTE

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.

HKS

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

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 5k

HDI

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 re-
sistance is 200k

W typ.

HDO

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 func-
tion.

Description

HFI

CMOS IN

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 200k

W typ.

An external RC network is recommended for input debouncing.

HFO

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 op-
eration or by another HFI input. Refer to the functional description for the hand-free
functional operation.

DOUT

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

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.

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.

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.

*/T
This key executes the P

®T function and waits a T

®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 tele-
phone 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.

The flash key can be selected as a digit or as a control
key by the option resistors R

K13

& R

K14

. Pressing the F

key will force the PO pin to be low for the T

duration and

is then followed by T

(sec). T

can also be selected by

K13

, R

K14

P
Pause key. The execution of this key pauses the out-
put for the T

duration. T

can be selected by R

K21

R
Redial key. Executes redialing as well as one-key re-
dial 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.

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.

EM1~EM3
One-touch memory dialing key. For speed-calling
convenience, they provide memory dialing in either
pulse or tone mode.

A
Auto key. When this key is pressed before pressing
any one of the digital keys (0~9) it executes the
two-touch memory function.

Keyboard operation

The following operations are described under an on/off- hook or on-hook condition with the hand-free active condition.
