5 FUNCTIONAL DESCRIPTION 5.1.4
PCD3332-2; PCD3332-3; PCD3332-S
CRADLE SWITCH INPUT (CSI)
References to the `PCD3332' or the `device' apply to the PCD3332-2, the PCD3332-3 and the PCD3332-S. 5.1 5.1.1 Pin description SUPPLY TERMINALS (VDD AND VSS)
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. Table 1 Different modes of the PCD3332 INPUT CE/FDI LOW LOW HIGH HIGH PCD3332 STATUS stop or power-down mode idle mode ringer mode conversation or off-hook mode
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. 5.1.2 OSCILLATOR INPUT/OUTPUT (XTAL1 AND XTAL2)
INPUT CSI LOW HIGH LOW HIGH
5.1.5
RESET INPUT (RESET)
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). 5.1.3 CHIP ENABLE AND FREQUENCY DISCRIMINATOR (CE/FDI)
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: * 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 k resistor, to save leakage current. 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. 5.1.6 PULSE DIAL AND FLASH OUTPUT (DP/FL)
INPUT
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. For AC inputs the pin acts as the (ringer) Frequency Discriminator Input (FDI). 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 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. Ringer response timing and detection is illustrated in Fig.15.
This pin is the output for: * The dial pulse sequence (DP) * 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. 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.

5.1.7 MUTE OUTPUT (MUTE)
PCD3332-2; PCD3332-3; PCD3332-S
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. The DC level of the TONE output measures 0.5VDD and the impedance is 100 (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.
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. This output is also activated if the device enters the programming mode, to avoid transmitting the keys entered. 5.1.8 DTMF OUTPUT (TONE)
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 2 DTMF frequency tolerances STANDARD FREQUENCY (Hz) 697 770 852 941 1209 1336 1477 Ringer melodies TONE 1 (Hz) 826 1037 1297

PCD3332-2; PCD3332-3; PCD3332-S
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.
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. 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 RINGER TONE ENABLE (RTE: PCD3332-2/S)
5.1.12.2
PCD3332-3
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 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. 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.
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 HANDS-FREE/RINGER TONE ENABLE (HF/RTE: PCD3332-3)
5.1.12.3
PCD3332-S
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. 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 VOLUME CONTROL OUTPUTS (VOL1 AND VOL2)
The PCD3332-S has the facility to control the ringer output signal by depressing the keys VOL- or VOL+ during the ringer mode. 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. 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.
5.1.12.1
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.

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. Keyboard detection is also performed in the ringer mode to enable the ringer volume setting and ringer melody selection. In the on-hook mode or power-down mode of the PCD3332-2 and PCD3332-S, the keyboard I/Os are set to HIGH except ROW 5 which is set to LOW.

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.
PCD3332-2; PCD3332-3; PCD3332-S
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.

PAUSE
Pressing the PAUSE key will insert an access pause during manual dialling and/or during programming. During manual dialling the pause time is not dialled, but is stored in the redial memory. This means that with manual dialling 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 an access pause is being dialled, the access pause in progress is terminated and dialling will continue at the next non-access pause digit. The access pause duration is option selectable.

To be able to build various telephone models by using the PCD3332, a possibility has been created to define different keypad layouts. e.g. a 13 number repertory dial consist of 10 numbers recalled via MRC + 0 to 9, and 3 direct access numbers M1, M2 and M3. A 10 number direct accessible dialler can be created by applying the keys M1 to M10 while a diode is connected at the MLA location.

Ringer Delay Selection (RDS: PCD3332-2)
If the diode is connected, then the actual ringer frequency validation is started after a delay of 100 ms. This is only performed at the start of each ringer burst signal.
During automatic transmission of a number in the DTMF mode the tone-on time and the pause time between two digits can be selected by option TBT A and TBT B. During manual dialling this option selects the minimum tone-on and pause time while the maximum time is determined by the time a key is depressed.

Pulse/Tone mode Selection (PTS)
The telephone set can be initially set to the PULSE or DTMF mode by switching on and off the diode in the matrix. The first entry of keys and # in the pulse dial mode will change the dial mode as well.

6.1.3.3 Manual dialling
PCD3332-2; PCD3332-3; PCD3332-S
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.
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. 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.
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. LNR functional examples: = Go on-hook = Go off-hook

Notepad function
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.
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
Repertory and chain dialling
6.1.3.6
Flash/Earth recall
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. The Flash/Earth will also refer the set to dial mode selected by the diode option.
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 MLA diode configuration (see Table 14) the procedure is as follows: * Direct repertory access: M1 to M10 * Two-key repertory access: MRC_0 to MRC_9. 6.1.5 RINGER MODE (PCD3332-2/S)
6.1.3.7
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 PROGRAMMING MODE
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.
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. 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)
6.1.4.1
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.
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. Depending on the diode RFS, 1 of 2 different input ringer frequency ranges is selected (see Table 13).

PCD3332-2; PCD3332-3; PCD3332-S
method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. 11.3.2 WAVE SOLDERING
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. 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). 11.2 11.2.1 DIP SOLDERING BY DIPPING OR BY WAVE
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. * The longitudinal axis of the package footprint must be parallel to the solder flow. * 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. 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. 11.3.3 REPAIRING SOLDERED JOINTS
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 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 REPAIRING SOLDERED JOINTS
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 SO REFLOW SOLDERING
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.
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
