FUNCTIONAL DESCRIPTION
References to the ‘PCD3332’ or the ‘device’ apply to the
PCD3332-2, the PCD3332-3 and the PCD3332-S.
5.1
5.1.1
CSI is normally generated from the physical ‘off-hooking’
of the phone. CSI in combination with CE/FDI determines
the operating mode of the PCD3332, as shown in Table 1.
Pin description
Table 1
SUPPLY TERMINALS (VDD AND VSS)
To retain data in the RAM, the standby supply voltage of
1 V, must be maintained. To ensure that the contents of
the RAM are secure in the event of a power failure, a
capacitor may be connected across the supply terminals.
The capacitor must have a suitable value to maintain the
standby voltage for a certain period of time. The minimum
operating voltage of these devices is 2.5 V. The internal
power-on reset is enabled for a voltage below this
minimum operating voltage.

RESET INPUT (RESET)
• CE going HIGH
• VDD falling below 2.5 V, then being restored (power-on
reset).
For this reason, RESET may not be required, and can be
connected to VSS. This should preferably be via a 100 kΩ
resistor, to save leakage current.
CHIP ENABLE AND FREQUENCY DISCRIMINATOR
(CE/FDI)
INPUT
Note that a suitable capacitor connected between VDD and
VSS will inhibit the decrease of voltage at VDD after a power
failure, and thus extend the time until the power-on reset is
initiated.
For DC inputs this pin acts as the chip enable (CE) input,
and is active HIGH. CE in combination with the Cradle
Switch Input (CSI) determines the mode of the device.
See Table 1.
5.1.6
For AC inputs the pin acts as the (ringer) Frequency
Discriminator Input (FDI).
PULSE DIAL AND FLASH OUTPUT (DP/FL)
This pin is the output for:
• The dial pulse sequence (DP)
To generate a correct ringer output tone, the input
frequency must be between 19.5 Hz and 57 Hz;
frequencies below 18 Hz and higher than 64 Hz are
omitted.
• The calibrated LOW pulse (FL) after the FLASH key is
pressed.
The dialling sequence for pulse dialling is shown in Figs 11
and 12. DP/FL starts HIGH, pulses are LOW, and the
inter-digit pauses are HIGH. Thus, DP/FL is HIGH during
a line-make and LOW during a line-break.
The PCD3332-3 has a second (diode selectable) range of
valid input frequencies of 14.5 Hz to 68 Hz; frequencies
below 14 Hz and higher than 76 Hz are omitted.
If the Flash/Earth diode option is set to FLASH, then when
FLASH is pressed a LOW pulse is output, with a calibrated
duration also determined by diode option.
Ringer response timing and detection is illustrated in
Fig.15.
1997 Jan 13
PCD3332 STATUS
RESET activates the on-chip reset circuit and is active
HIGH. The reset circuit initializes all inputs and outputs.
Two other events will cause the chip to initialize:
The time base for the PCD3332 is a crystal-controlled
on-chip oscillator, which incorporates a 3.58 MHz crystal
or ceramic resonator connected between XTAL1 and
XTAL2. It should be noted that when using a ceramic
resonator, the minimum supply voltage increases.
The oscillator starts when VDD reaches its operating
voltage level and CE = HIGH (min. 2.5 V).

RC low-pass filter. Therefore, the total harmonic distortion
fulfils the CEPT CS203 recommendations. An on-chip
reference voltage provides output tone levels independent
of supply voltages and temperatures. Spread among the
individual parts is extremely low.
MUTE OUTPUT (MUTE)
During the dialling sequence this push-pull output is
activated. In the pulse dialling mode, MUTE goes HIGH
prior to the dialling action and goes LOW after the last
tidp (interdigit pause), see Figs 11 and 12. In DTMF
dialling, MUTE goes HIGH prior to the dialling action and
goes LOW after an additional ‘holdover’ time, see
Figs 13 and 14.
The DC level of the TONE output measures 0.5VDD and
the impedance is 100 Ω (typ.). Table 2 shows the
frequency tolerances.
The TONE output is also used to generate the ringer
melody, key entry acceptance beep, error or warning
beeps and confirmation beeps. These beeps are
generated/set in programming mode as a response to the
users action. The ringer is designed to generate
3-melodies that may be selected using the keyboard.
Table 3 shows the implemented ringer melodies.
This output is also activated if the device enters the
programming mode, to avoid transmitting the keys
entered.
DTMF OUTPUT (TONE)
5.1.8
The timing sequence for DTMF dialling is illustrated in
Figs 13 and 14. The tones generated by this TONE are
filtered by an on-chip switched capacitor filter, and active

Table 5 shows the volume outputs setting, as well as the
default setting in case of a power failure or if the power is
supplied for the first time.
REGISTER RECALL (EARTH)
If the Flash/Earth diode option of the PCD3332 is set to the
Earth, then dialling the EARTH either out of
Repertory/LNR or by pressing the FLASH key will
generate a HIGH pulse at the push-pull output EARTH for
a calibrated time. Figures 12 and 14 illustrate the EARTH
timing relationship with other signals. The calibrated
EARTH time is followed by an interdigit time tidp. A second
dialling of EARTH can only be performed after the interdigit
time has elapsed.
5.1.12.2
The PCD3332-3 has the facility to control the ringer output
signal and the loudspeaker signal during listening-in or
hands-free operation. Depressing the keys VOL− or VOL+
during the ringer mode will change the ringer volume
setting. Depressing the keys VOL− or VOL+ during the
conversation mode will change the loudspeaker volume
setting.
If the Flash key was the first key depressed directly after
going off-hook, followed by a second depressing of the
Flash key while the EARTH is still in progress, then the
second depression will be ignored.
5.1.10
If the maximum volume level is reached, depressing the
VOL+ key will not change the volume setting. If the
minimum volume level is reached, depressing the VOL−
key will not change the volume setting. Selection between
ringer volume or conversation mode volume, is performed
in the hardware using the HF/RTE output. In the ringer
mode the output HF/RTE is HIGH.
RINGER TONE ENABLE (RTE: PCD3332-2/S)
The PCD3332-2 and PCD3332-S generate tones for the
ringer output stage and key tones when depressing a
function key at the keypad. Output RTE will go HIGH and
stay HIGH for the duration of the tone generated at output
TONE.
5.1.11
Table 5 shows the volume outputs setting, as well as the
default setting in case of a power failure or if the power is
supplied for the first time.
HANDS-FREE/RINGER TONE ENABLE (HF/RTE:
PCD3332-3)
5.1.12.3
If the maximum volume level is reached, depressing the
VOL+ key will not change the volume setting. If the
minimum volume level is reached, depressing the VOL−
key will not change the volume setting. Selection between
ringer volume or conversation mode volume, is performed
in the hardware using the RTE output. In the ringer mode
the output RTE is HIGH.
During the conversation mode, HF/RTE is used for
enabling the hands-free mode. Depressing the HOOK key
will change the operation mode as follows:
• Change from on-hook (stop mode) to hands-free mode
• Toggles the listening-in mode
• Change from handset to hands-free.
5.1.12.1
Table 5 shows the volume outputs setting, as well as the
default setting in case of a power failure or if the power is
supplied for the first time.
VOLUME CONTROL OUTPUTS (VOL1 AND VOL2)
PCD3332-2
The PCD3332-2 has the facility to control the ringer output
signal, as well as the loudspeaker volume, by depressing
the keys ∗/VOL− or #/ VOL+ during the ringer mode.
If the maximum volume level is reached, depressing
#/VOL+ key will not change the volume setting. If the
minimum volume level is reached, depressing ∗/VOL− key
will not change the volume setting. Selection between
ringer volume or conversation mode volume, is performed
in the hardware using the RTE output. In the ringer mode
the output RTE is HIGH.
1997 Jan 13
PCD3332-S
The PCD3332-S has the facility to control the ringer output
signal by depressing the keys VOL− or VOL+ during the
ringer mode.
The PCD3332-3 generates tones for the ringer output
stage and key tones when depressing a function key at the
keypad. Output HF/RTE will go HIGH and stay HIGH for
the duration of the tone generated at output TONE.

A single contact keyboard with a maximum of 6 columns
and 5 rows can be connected to the PCD3332-2.
The keyboard scanning is started if a key depression is
detected. The rows are scanned while the columns are
used as sense inputs.
To overcome key bouncing, a debounce on/off time of
approximately 14 to 20 ms is implemented.

Only one single key depression is validated and accepted
at any one time. Once a key is accepted the keyboard
scanning is continued until no further keys are depressed.
This means that if a key is accepted but still depressed
while a second key is entered, the second key depression
is ignored. Also, if two or more keys are depressed within
the debounce time while no key is yet accepted, all keys
are ignored.

In the on-hook mode or power-down mode of the
PCD3332-3, the keyboard I/Os are set to HIGH except
ROW 5 which is set to LOW. In this instance, depression
of the HOOK key can be detected by the external
hardware circuitry and converted to an active HIGH signal
which is passed to CE in order to ‘wake-up’ the
PCD3332-3.
When the HOOK key has been accepted the PCD3332-3
enters the hands-free mode.

ROW 5 was used to detect the HOOK key, this function is
deleted.
ROW 5 is an open-drain input, this configuration is used to
avoid current flowing in the on-hook mode or power-down
mode. A pull-up resistor should be connected to ROW 5.
The keyboards which the PCD3332-2, PCD3332-3 and
PCD33332-S support are shown in Figs 6, 7 and 8
respectively. The figures also show the diode options as
‘dotted’ keys.

the user actually waits for the dial tone before dialling is
continued. Repertory and LNR dialling however, will dial
out the access pause. If the pause key is depressed while

OPERATING PROCEDURES
6.1
Operating modes
The PCD3332-2/S has 4 operating modes:
6.1.2
1. On-hook mode or ringer mode
Lifting the cradle (handset) or pressing the hook key will
put the set in the conversation mode, an accepted key
entry is processed and may initiate the following:
2. Off-hook mode or conversation mode
3. Programming mode or store mode
• Dialling the digits entered
4. Dial mode.
• Redialling the previously entered digits
The PCD3332-3 has 4 operating modes:
• Dialling out a repertory memory
1. On-hook mode or ringer mode
• Enter programming mode.
2. Conversation mode which is divided into hands-free
mode and listening-in mode
6.1.3
3. Programming mode or store mode
RESET DELAY TIME
All modes, except for the ringer mode, are terminated by a
line break (CE is deactivated), or by going on-hook. If this
condition is detected, the reset delay time is initiated.
The set will not enter the on-hook state unless the reset
delay has expired. In the event of a line break, the set will
remain in the actual operation mode if the line-break is
ended while the reset delay is still in progress (see Fig.10).
4. Dial mode.

If the key-in rate causes both the redial register and FIFO
register to overflow, the PCD3332-2 will return to the
conversation mode and no keyboard entries will be
accepted.
Manual dialling
During digit entry, the device immediately starts to transmit
the digit(s). The minimum transmission time is unaffected
by the speed of entry. Transmission continues as long as
further data input has to be processed. Up to 32 digits can
be stored in the redial register.
6.1.3.4
Last number redial
If the first key entered is the LNR key, the stored LNR
number is dialled out. LNR can hold a maximum of
32 digits. LNR is inhibited If more than 32 digits are
entered, normal dialling however is continued.
After the main register overflows, a 10 digits First-In
First-Out register (FIFO) takes over as buffer. After
transmitting the first digit of the FIFO register this position
is automatically cleared to provide space for storing new
data. In this way, the total number of digits which can be
transmitted is unlimited, provided the key-in rate is not
excessive.

Access pause dialling and termination
6.1.4.2
Access pauses entered during manual dialling or repertory
number storage are not dialled out, but are stored. When
LNR or a repertory number is selected for redial, the
access pauses are dialled out. If at LNR or repertory dial,
an access pause is being dialled out, then depressing the
PAUSE key will terminate the access pause in progress
and dialling will continue at the first non-access pause
digit.
6.1.3.6
In the speech mode, a number can be entered on the
keyboard. This number may be dialled out at the next
off-hook situation by LNR or may be entered in memory.
This function effectively mimics a notepad for a number
passed during a telephone conversation.
6.1.4.3
Flash/Earth recall
Depending on the MLA diode configuration (see Table 14)
the procedure is as follows:
The Flash/Earth will also refer the set to dial mode
selected by the diode option.
• Direct repertory access: M1 to M10
• Two-key repertory access: MRC_0 to MRC_9.
Data dialling in the pulse dialling mode
If the PCD3332 is initially set to the pulse dial mode
(PTS = ON), depressing the TONE, ∗ or # key will continue
dialling in the DTMF mode. Flash/Earth recall will restore
the pulse dialling mode.
6.1.4
6.1.5
PROGRAMMING MODE
Depending on the diode RMS, either a default ringer
melody is selected, or 1 out of 3 ringer melodies may be
selected from the keypad (see Table 12).
6.1.6
RINGER MODE (PCD3332-3)
The PCD3332-3 has a built-in frequency discriminator
circuit, with CE/FDI being used as the discriminator input.
If the ringer frequency supplied is accepted, a ringer
melody is generated. When the ringer melody sounds, the
ringer volume is adjustable in 4 steps using the ∗/VOL−
and #/VOL+ keys.
Memory overflow
A total of 250 digits can be stored. If an attempt is made to
store a number which will bring the total amount of digits
stored to over 250, the TONE output will generate the
memory overflow beeps and the store procedure is
cancelled.
1997 Jan 13
RINGER MODE (PCD3332-2/S)
The PCD3332-2/S has a built-in frequency discriminator
circuit, with CE/FDI being used as the discriminator input.
If the ringer frequency supplied is accepted, a ringer
melody is generated. When the ringer melody sounds, the
ringer volume is adjustable in 4 steps using the ∗/VOL−
and #/VOL+ keys.
The PCD3332 has an on-chip CMOS RAM which can
store up to 10 numbers of 32 digits with a total of 250 digits
(floating memory). If the memory overflows, a warning
beep is generated. If the controller is initially set to the
pulse dial mode, digits can be stored in the pulse dial
and/or in the DTMF mode by depressing key ∗ or # or
using the ‘change mode’ procedure during the store
procedure. This function is best illustrated in Table 22.
6.1.4.1
Repertory and chain dialling
Repertory numbers can be dialled out before or after
manual dialling or LNR, and can be entered one after
another in a chain. However, during transmission of LNR
or a repertory number, a subsequent repertory number is
not accepted. This means that a repertory number can
only be entered if the previous repertory dial or LNR is
ended.
Depending on the option selected (see Table 8),
depressing the Flash key will generate a calibrated
Flash time at output DP/FL, or a calibrated earth time on
the EARTH output. The calibrated earth time is 400 ms,
the flash time is set by diodes as shown in Table 7.
6.1.3.7
Notepad function
Depending on the diode RFS, 1 of 2 different input ringer
frequency ranges is selected (see Table 13).

method. Typical reflow temperatures range from
215 to 250 °C.
11 SOLDERING
11.1
Introduction
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
11.3.2
WAVE SOLDERING
Wave soldering techniques can be used for all SO
packages if the following conditions are observed:
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
11.2
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
11.2.1
DIP
• The package footprint must incorporate solder thieves at
the downstream end.
SOLDERING BY DIPPING OR BY WAVE
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (Tstg max). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
11.2.2
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
REPAIRING SOLDERED JOINTS
11.3.3
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
11.3
11.3.1
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
SO
REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO
packages.
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
