GENERAL DESCRIPTION
The PCD3310 and PCD3310A are single-chip silicon gate
CMOS integrated circuits. They are dual-standard diallers
for pulse or dual tone multi-frequency (DTMF) dialling, with
on-chip oscillators suitable for use with 3.58 MHz crystals.
– Change from pulse dial to DTMF dial in
mixed mode (>)
• DTMF timing:
Input data is derived from any standard matrix keyboard
for dialling in either the pulse or DTMF mode.
– for manual dialling, maximum duration burst/pause
intervals are user-determined, but at least minimum
duration burst/pause intervals are ensured
Numbers up to 23 digits can be retained in RAM for
dialling/redialling.
– for redial, minimum duration burst/pause intervals are
used

FUNCTIONAL DESCRIPTION
7.3
Chip enable (CE)
References to ‘the device’ apply to both the PCD3310 and
the PCD3310A.
The CE input enables the device and is used to initialize
the device. When CE is LOW it provides the static standby
condition. In this state the clock oscillator is disabled, all
registers and logic are reset with the exception of the redial
registers, Read Address Counter (RAC), Write Address
Counter (WAC) and Temporary Write Address Counter
(TWAC). The RAC points to the first digit of the last
number dialled, the WAC and TWAC point to the last
entered digits in the main and temporary registers
(see Fig.6). The keyboard input is inhibited, but data
previously entered is saved in the redial registers provided
VDD is higher than Vstb. The current drawn is Istb (standby
current) and serves to retain data in the redial registers
during hook-on.
7.1
Power supply (VDD and VSS)
The positive supply of the device (VDD) must meet the
voltage requirements as indicated in Chapter 11.
To avoid undefined states of the device at power-on, an
internal reset circuit clears the control logic and counters.
If VDD drops below the minimum standby supply voltage of
1.8 V the power-on reset circuit inhibits redialling after
hook-off. The power-on reset signal has the highest
priority; it blocks and resets the device without delay
regardless of the state of chip enable input (CE).
When CE is HIGH it activates the clock oscillator and the
device changes from static standby condition to the
conversation mode. The current consumption is IDD(conv)
until the first digit is entered from the keyboard. Then a
dialling or redialling operation starts. The operating current
is IDD(pulse) if in the pulse dialling mode, or IDD(DTMF) if the
DTMF dialling mode is selected.
7.2
Clock oscillator (OSCI and OSCO)
The timebase for the device for both pulse and DTMF
dialling is a crystal controlled on-chip oscillator which is
completed by connecting a 3.58 MHz crystal or ceramic
resonator between the OSCI and OSCO pins.
Recommended resonator type:
• 3.58 MHz PXE - Murata; CSA 3.58MG310VA.

If the CE input is taken to a LOW level for longer than time
period trd (see Figs 11 and 12 and Chapter 12) an internal
reset pulse will be generated at the end of the trd period.
The system changes to the static standby state. Short CE
pulses of < trd will not affect the operation of the device and
reset pulses are not produced.
entries are debounced on both the leading and trailing
edges for approximately time period te as shown in
Figs 11, 12, 13 and 14. Each entry is tested for validity.
When a key is depressed, keyboard scanning starts and
only returns to the sense mode after release of that key.
7.4
Mode selection (PD/DTMF)
7.4.1
PULSE MODE
If PD/DTMF = VSS the pulse mode is selected. Entries of
non-numeric keys are neglected, they are neither stored in
the redial register nor transmitted.

If PD/DTMF = VDD the dual tone multi-frequency dialling
mode is selected. Each non-function key activated
corresponds to a combination of two tones, one of four
LOW and one of four HIGH frequencies, corresponding to
the key’s row and column in the keyboard matrix.
See Fig.4 and Table 3. The frequencies are transmitted
with a constant amplitude, regardless of power supply
variations. Harmonic content is filtered out thus meeting
the CEPT recommendations.

KEYBOARD
The transmission time is calibrated for redial. In manual
operation the duration of bursts and pauses is the actual
key depression time, but not less than the minimum
transmission time (tt) or minimum pause time (tp).
Fig.4 Keyboard organization.
ROW 5 of the keyboard contains the following function
keys:
7.4.3
MIXED MODE
• P = memory clear and programming (notepad)
• FL = flash or register recall
• R = redial
When the PD/DTMF pin is open-circuit the mixed mode is
selected. After activation of CE or FL (Flash) the device
starts as a pulse dialler and remains in this state until a
non-numeric dial key (A, B, C, D, , #) or the function key >
is activated. Pressing a non-numeric dial key causes the
corresponding DTMF tones to be output, and any
subsequent dialling to be in DTMF mode. Pressing >
causes no output tones, but any subsequent dialling is in
DTMF mode. The > key should be used if the first DTMF
output required is numeric. The device remains in DTMF
dial mode until FL is activated or after a static standby
condition when CE is re-activated.
• > = change of dial mode from pulse to DTMF in mixed
dialling mode.
In the pulse dialling mode the valid keys are the
10 numeric dial keys (0 to 9). The non-numeric dial keys
(A, B, C, D, , #) have no effect on the dialling or the redial
storage. Valid function keys are P, R and FL.
In the DTMF mode all dial keys are valid. They are
transmitted as a dual tone combination and at the same
time stored in the redial register. Valid function keys are P,
FL and R.
A connection between the PD/DTMF pin and VDD also
initiates DTMF dialling. Chip enable, FL or a connection of
PD/DTMF pin to VSS sets the device back to pulse dialling.
In the mixed mode all key entries are valid and executed
accordingly.

Keyboard inputs/outputs
The sense column inputs COL 1 to COL 4 and the
scanning row outputs ROW 1 to ROW 5 of the device are
connected to the keyboard as shown in Fig.4. All keyboard

Product specification
Pulse and DTMF diallers with redial
PCD3310; PCD3310A
When the DTMF mode is selected output tones are timed
in manual dialling with a minimum duration of bursts and
pauses, and in redial with a calibrated timing. Single tones
may be generated for test purposes (CE = HIGH). Each
row and column has one corresponding frequency.
High group frequencies are generated by connecting the
column to VSS and LOW group frequencies are generated
by forcing the row to VDD. The single tone frequency will be
transmitted during activation time, but it is neither
calibrated nor stored.
7.6
Flash duration control (FLD)
Flash (or register recall) is activated by the FL key and can
be used in DTMF and pulse dialling modes.
The FL key has the same effect as placing the telephone
‘on-hook’ for a calibrated time. Pressing the FL key will
produce a timed line-break of 100 ms (min.) at the DP/FLO
output. During the conversation mode pressing FL also
acts as a chip enable. The flash pulse duration (tFL) is
calibrated and can be prolonged with an external resistor
and capacitor connected to the FLD input/output (see
Fig.5). The flash pulse resets the Read Address Counter
(RAC) to the address of the first entered digit of the last
number dialled. Subsequent redial is possible (see Fig.9).
The counter of the reset delay time is held for a period of
tFL.
An on-chip reference voltage provides output tone levels
independent of the supply voltage. Table 3 shows the
frequency tolerance of the output tones for DTMF
signalling.
7.7
TONE output (DTMF mode)
The single and dual tones which are provided at the TONE
output are filtered by an on-chip switched capacitor filter,
followed by an on-chip active RC low-pass filter. Hence,
the total harmonic distortion of the DTMF tones meets the
CEPT recommendations. The tone output has the
following states:
• tone OFF; 3-state
• tone ON; the associated frequencies are superimposed
on a DC level of 1⁄2VDD

valid digit, the Temporary Write Address Counter (TWAC)
will be set to the first address of the temporary register,
and the decoded digit will be stored in the temporary
register at that address. The TWAC is then incremented to
the next address. The first 5 valid digits will be decoded
and stored in the temporary register in this way, and have
no effect on the main register and its associated Write
Address Counter (WAC). After the sixth valid digit is
entered, the TWAC indicates an overflow condition.
The data from the temporary register will be copied into the
5 least significant places of the main register and the
TWAC into the WAC. The sixth digit, and all subsequent
digits will be stored in the main register (a total of not more
than 23). If more than 23 digits are entered redial will be
inhibited. If not more than 5 digits are entered only the
temporary register and the associated TWAC are affected.
7.8
Dial pulse and Flash output (DP/FLO)
This is a combined output which provides control signals
for timing in pulse dialling or for a calibrated line break
(flash or register recall) in both dialling modes.
7.9
Mute output (M1)
The MUTE output can be used to disable the microphone
during dialling.
During pulse dialling the mute output becomes active
HIGH for the period of the inter-digit pause, break time and
make time. It remains at this level until the last digit is
pulsed out.
During DTMF dialling the mute output becomes active
HIGH for the period of tone transmission and remains at
this level until the end of hold-over time. It is also active
HIGH during flash and flash hold-over time.
All entries are debounced on both the leading and trailing
edges for at least time period te as shown in Figs 11, 12,
13 and 14.
7.10 Mute output (M1)
Each entry is tested for validity before being stored in the
redial registers.
Inverted output of M1. In the PCD3310P it is only available
as a bonding option of M1.
• For DTMF dialling all dial keys are valid
• For pulse dialling only numeric dial keys are valid.
7.11 Muting output (M2)
Simultaneous to their acceptance and corresponding to
the selected mode (pulse, DTMF or mixed), the entries are
transmitted as pulse-trains or as DTMF frequencies in
accordance with PTT requirements. Non-numeric dial key
entries are neglected during pulse dialling; they are neither
stored nor transmitted.
Active HIGH output during actual dialling; i.e. during break
or make time in pulse dialling, or during tone ON/OFF in
DTMF dialling. It is an open drain p-channel output.

DIALLING PROCEDURES (see Figs 7, 8 and 9)
8.1
Dialling
After CE has risen to VDD the oscillator starts running and
the Read Address Counter (RAC) is set to the first address
of both the main and temporary redial registers, ready to
redial any stored number (see Fig.6). By dialling the first

Philips Semiconductors
Product specification
Pulse and DTMF diallers with redial
PCD3310; PCD3310A
During redial keyboard entries (function or non-function)
are not accepted until the device returns to the
conversation mode after completion of redialling. No redial
activity takes place if one of the following events occur:
8.2
Redialling
After CE has risen to VDD the oscillator starts running.
The address of the first digit in the redial register is stored
in the RAC, and the device is in the conversation mode.
If ‘R’ is the first keyboard entry the device starts redialling
the contents of the temporary register. If the overflow flag
of the TWAC was set in the previous dialling, the redialling
continues in the main register.
• Power-on reset
• Memory clear (‘P’ without subsequent data entry)
• Memory overflow (more than 23 valid data entries).
8.3
Notepad
Because access to an external line from a PABX usually
involves dialling an access code and waiting for an access
tone, a ‘one-press’ redial may fail due to insufficient delay
between the access code and the external number.
For this reason, the access code should be redialled. If the
access code (up to 4 digits) matches the first part of the
stored number, then pressing R after the access tone is
obtained will cause the rest of the number to be redialled
(see Fig.7, PABX).
The redial register can also be used as a notepad. In the
conversation mode a number with up to 23 digits can be
entered and stored for redialling. By activating the program
key (P) the WAC and TWAC pointers are reset. This acts
like a memory clear (redial is inhibited). Afterwards, by
entering and storing any digits, redialling will be possible
after flash or hook-on and hook-off (see Fig.9).
During notepad programming the numbers entered will not
be transmitted nor is the mute active, only the confidence
tone is generated.
Timing in the DTMF mode is calibrated for both tone bursts
and pauses.
In mixed mode only the first part entered (the pulse dialled
part of the stored number) can be redialled.

HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, it is good practice to take
normal precautions appropriate to handling MOS devices (see “Data Handbook ICO3, Section: General, Handling MOS
devices”).

Product specification
Pulse and DTMF diallers with redial
PCD3310; PCD3310A
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
15 SOLDERING
15.1 Introduction
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.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
15.3.2 WAVE SOLDERING
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).
Wave soldering techniques can be used for all SO
packages if the following conditions are observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
15.2 DIP
15.2.1 SOLDERING BY DIPPING OR BY WAVE
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
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.
• The package footprint must incorporate solder thieves at
the downstream end.
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.
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.
15.2.2 REPAIRING SOLDERED JOINTS
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
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.
15.3.3 REPAIRING SOLDERED JOINTS
Fix the component by first soldering two diagonally-
opposite 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.
15.3 SO
15.3.1 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.
