General Description
lock function. The six versions also supply the hold-line
and hand-free functions, which are suitable for feature
phone applications.
The HT9320 series tone/pulse dialers are CMOS LSI for
telecommunication systems. They are designed to meet
various dialing specifications through resistor option
matrix.

one-touch/two-touch memory dialing. If the keyboard includes M1~M20 keys it can be used as one-touch memory dialing. Otherwise, it works as two-touch
(PAGE®M1~M10) or three-touch(A®PAGE®0~9)
memory dialing for speed dialing in either pulse or tone
mode.
The HT9320 series are offered in six different versions.
The different functions of the six versions are listed in
the selection table. The HT9320A, HT9320H versions
provide the on-hook store function; the HT9320B version provides the LCD interface function; the HT9320K
version provides the keytone function; the HT9320L version provides both the LCD interface function and IDD

Description
CMOS
IN/OUT
These pins form a 5´8 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~C8) remains
low and the row group (R1~R5) is set high for key input detection.
For the HT9320L-X, the column group remains high and the row group is set
low for key input detection.
An inexpensive single contact 5´8 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.
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.
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 stand-by 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, used 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 the tone mode. When the chips are in tone mode,
switching to the 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.

Description
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.
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.
An external RC network is recommended for input debouncing. The pull-low
resistance of HFI is 200kW typ.
O
I
HFO
O
CMOS OUT
The HFO is a CMOS output structure. Its output is toggle- controlled by a positive transition on the 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 an on-off-hook operation or by
another HFI input or by setting HDO high. Refer to the functional description
for the hand-free function 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 clock.

Resistor
C1~C8 and R1~R5 form a keyboard matrix. Together
with a standard 5´8 keyboard, the keyboard matrix is
used for dialing entries. In addition, the keyboard matrix
also provides resistor options for different dialing specification selections. The keyboard arrangement for the
HT9320 series are shown in the Keyboard Information.

Lock function (HT932L)
Hold-line function operation
This function aims to detect lock dialing numbers to prevent from an unauthorized long distance call. The dialing
output of this chip is disabled if the first input key after
on-off hook is the lock number when the lock function is
enabled.
· Hold-line function execution
When HDO is low, a falling edge triggers the HDI, enabling the Hold-line function (HDO becomes high).
The XMUTE remains low when HDO is high.
· Reset Hold-line function
When HDO is high, the Hold-line function is enabled
and can be reset by:

· SA
· ST
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.
Store key. The execution of this key actuates the store
memory function with (or without) dialing output. During the dialing signal transmission, the ST key is inhibited.
· A
· F
Auto key. When this key is pressed before pressing
any one of the digital keys (0~9) it executes the
two-touch/ three-touch memory dialing function.
The flash key can be selected as a digit or as 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.
· PAGE
M11~M20 are represented by pressing the PAGE key
and the digital keys (0~9) or M1~M10. That is to say,
A PAGE digit key (0~9) or PAGE®M1~M10 executesM11~M20memorydialing.
· P
Pause key. The execution of this key can pause the
output for the TP duration. TP can be selected by RK21.
· M1~M20
· R
One-touch memory dialing for speed-dialing in either
pulse or tone mode.
Redial key. Executes redialing as well as one-key redial function.
· 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.
