1997 jan 15 6 philips semiconductors product speci?cation multistandard repertory dialler/ringer with eeprom pcd3330-1 5 functional description 5.1 inputs/outputs 5.1.1 col1 to col6, keyboard inputs the sense column inputs col1 to col6 and the scanning row outputs row1 to row6 can be directly connected to several keyboard layouts, up to a maximum 6 6 single contact keyboard matrix. four of the sense columns are used to store the contents of the eeprom in the factory (see section 5.3). 5.1.2 dmo, dial mode output this output is high during the make and break times in pulse dial mode. its function is to lower the dc line voltage during these pulses. this output is low during dtmf dialling, during the inter-digit-pause in pulse dial mode and during conversation mode. 5.1.3 hook, on / off hook detection input if inputs ce and hook are both high then the conversation, programming or dialling mode is selected. switching the hook input low longer than the reset-delay-time results in switching to the standby mode. if ce = high and hook = low the pcd3330-1 is in the ringer mode. 5.1.4 xtal1 and xtal2, oscillator input / output time base for the pcd3330-1 is a crystal-controlled on-chip oscillator which is completed by connecting a 3.579545 mhz crystal or ceramic resonator (pxe) between xtal1 and xtal2. the xtal2 is the oscillator output and can be used as driver for another oscillator input. a low-cost quartz crystal from philips (code number. 4322 143 04401) is available, specially for telephony applications. the oscillator starts when v dd reaches the operating voltage level and ce = high. 5.1.5 reset, reset input when the reset pin is connected to v ss , a reset is generated by an internal power-on-reset circuit, which produces an internal reset pulse every time that the supply voltage v dd crosses the power-on-reset voltage level (typ. 2.0 v). depending on the application it can be necessary to generate a reset via an external circuit (e.g. an external rc network). when the reset input becomes high it initializes the ic. the reset-pin should not be left open (not-connected) in any circumstances. 5.1.6 ce/rf, chip enable and ringer - frequency detect input as chip enable input (active high) it is used to initialize part of the system, to switch from standby to the ringer or conversation, programming or dialling mode and to detect line breaks. as ringer-frequency input it measures the time between two low-to-high transitions, thus measuring the ringer frequency. 5.1.7 row1 to row6, keyboard outputs the scanning row outputs row1 to row6 and the sense column inputs col1 to col6 can directly be connected to several keyboard layouts (max. a 6 6 single contact keyboard matrix). 5.1.8 mute, mute output the mute output is used during dialling. in the pcd3330-1 the mute output has four different selectable options: m1, normally low, but high during inter-digit-pause and make/break in pulse dial mode, during tone-on and tone-off in dtmf mode, and during flash or earth m1, the inverted signal of m1 m2, normally low, high during make/break in pulse dial mode, during tone-on in dtmf mode, and during flash or earth m2, the inverted signal of m2. each time the m-key on the keyboard is pressed the mute output goes to its inverted state. 5.1.9 rto, ringer tone output this is the special ringer output. when this output is selected the output of the internal tone generators is not connected to the tone output but to this rto output. the ringer output signal has a peak to peak square output voltage of v dd - v ss (this is used with a pxe transducer). 5.1.10 dp/ fl, pulse dialling and register recall output the dp/ fl output drives an external switching transistor in pulse dial mode.
1997 jan 15 7 philips semiconductors product speci?cation multistandard repertory dialler/ringer with eeprom pcd3330-1 it pulses a calibrated flash or register recall pulse (if selected) when the keyboard input flash is pressed. 5.1.11 v dd and v ss v dd and v ss are the supply terminals. 5.1.12 tone, dtmf or ringer tone output in dtmf dialling mode the dual tones which are provided at the output tone are filtered by an on-chip switched capacitor filter, followed by an active rc low-pass filter. therefore, the total harmonic distortion of the dtmf tones fulfils the cept recommendations. an on-chip reference voltage provides output tone levels independent of supply voltages. the impedance is 100 w typically. in ringer mode this tone output can be used for generating the ringer output tones. whether this tone output or the special rto (ringer tone) output is used is selected via eeprom. 5.1.13 pd/dtmf, pulse / tone mode selection to select the dialling mode, this input pd/dtmf must be connected to v dd or v ss . pd/dtmf = high (v dd ) = dtmf mode. pd/dtmf = low (v ss ) = pulse mode. the pcd3330-1 accept the information also during manual dialling. switching the input to pin pd/dtmf changes the dialling mode after finishing the digit in progress. 5.1.14 rvol1 and rvol2/lse, ringer volume outputs the rvol1 and rvol2 outputs can be used to control the ringer output volume in four steps. the volume can be changed via keyboard during ringing or conversation mode (off-hook). the selected output level is stored in eeprom. during on-hook dialling the rvol2 output becomes the lse output for switching the listening-in amplifier. when the on-hook dialling option is not selected and the microphone mute option is active output lse change to a microphone mute which is controlled by the m-key. after off-hook this output is high and will toggle by every press off the m-key. 5.1.15 earth, a/b line to earth connection the earth output drives an external switching transistor. which connects the a- or b-line to earth. it pulses a calibrated earth pulse (if selected) when the keyboard input flash is pressed. 5.2 keyboard the pcd3330-1 is programmed to work with various keyboards which can be connected to the sense column inputs col1 to col6 and the scanning row outputs row1 to row6. in this specification four examples are given: figure 2. the simplest keyboard. all basic functions are available but only 2-key abbreviated dialling (mem + digit) is possible. figure 3. as fig.2 but with 3 extra 1-key abbreviated dialling keys. figure 4. as fig.2 but the 10 repertory numbers can be reached via m0 to m9 with 1-key abbreviated dialling. figure 5. the most complex keyboard. a second possibility for column 4 exists. this column can be selected via eeprom. keyboard entries are valid 20 ms (debounce time) after the leading edge of a keyboard entry.

1997 jan 15 15 philips semiconductors product speci?cation multistandard repertory dialler/ringer with eeprom pcd3330-1 the sto-key will end the programming procedure, whereas after the lnr-key a new byte can be selected to have the required bit changed. 5.4 operation mode overview the pcd3330-1 has in total five operation modes: standby, conversation, ringer, dialling and programming. the state diagram is given in fig.7. when both ce/rf and the hook input are low the pcd3330-1 goes to the standby mode, in which the contents of the redial register is refreshed, the oscillator switched off and the device enters the low current state. a high state on the ce/rf and/or the hook input will cause a complete initialization of the pcd3330-1 which means setting of the i/o pins, clearing of the ram and reloading the eeprom contents into it. 5.5 pulse/dtmf dialling function 5.5.1 p ulse /dtmf mode selection by pin the pcd3330-1 has two dialling modes, pulse dialling and dual tone multi frequency (dtmf). these can be selected via the pd/dtmf input in the following way: pd/dtmf = high (v dd ) = dtmf mode. pd/dtmf = low (v ss ) = pulse mode. the controller accepts the information also during manual dialling. switching the input to the pin pd/dtmf changes the dialling mode after transmitting the digit in progress. fig.7 state diagram of the pcd3330-1 dialler/ringer. handbook, full pagewidth mgg577 dialling conversation standby programming ringer end dial start dial sto-key sto-key ce/rf = 1 hook = 1 ce/rf = 0 hook = 0 ce/rf = 1 hook = 1 ce/rf = hook = 0 ce/rf = hook = 0 ce/rf = hook = 0 hook = 0 ce/rf = ac
1997 jan 15 16 philips semiconductors product speci?cation multistandard repertory dialler/ringer with eeprom pcd3330-1 5.5.2 p ulse dialling (pd/dtmf = low) the keyboard entry initiates a recall of a previously stored number or is a simultaneous keying-in and pulsing-out activity, with storing for possible later recall. if in the recalled number or at keying-in the keys a,b,c or d (options a to d keys selected) are used these digits are not transmitted. if at keying-in the keys * or # are used this results in a switch over to dtmf dialling. normally, keying in is faster than pulsing-out (fed from the redial register). pulse sequences start with an inter-digit pause of 840 ms duration, followed by a sequence of pulses corresponding to the present digit in store. each pulse starts with a mark (line break) followed by space (line make). the pulse period is 100 ms with a mark-to-space ratio of 3:2or2:1 (mark-to-space ratio selection). after transmission of a digit, the next digit is processed, again starting with an inter-digit pause. the pulses are available at the dp/ fl output and can be used to drive an external switching transistor in pulse dialling mode. the transmission ic is put in the dialling mode by means of output mute. output mute has several programmable options, mute can be configured as m1, m1, m2 and m2. in fig.8 the timing diagram of these output possibilities is given. after completion of the number string the circuit changes from dialling mode to conversation mode. 5.5.3 d ual tone multi frequency (dtmf) dialling (pd/dtmf = high) the pcd3330-1 converts keyboard inputs into data for the on-chip dtmf generator. tones are transmitted via output tone with six programmable minimum tone burst/pause durations of 60/90, 70/70, 80/80, 100/100, 100/140 or 140/140 ms. the maximum tone burst duration is equal to the key depression time. with redial and repertory dialling tones are automatically fed at the programmed rate. again the mute output has several programmable options namely, m1, m1, m2 and m2. in fig.9 the timing diagram of these output possibilities is given. fig.8 timing diagram in pulse mode, showing dp/ fl and mute outputs. handbook, full pagewidth mgg578 t m t b t id t m t b t id ce keyboard entry m1 m1 m2 m2 dp/fl handset lifted handset replaced 23

1997 jan 15 18 philips semiconductors product speci?cation multistandard repertory dialler/ringer with eeprom pcd3330-1 5.5.7 m ute function (m- key ) when no dialling or programming is active, every time this m-key is pressed the mute output goes to the active or inactive state depending on its previous status. when the mute output is in the active state and another key is pressed then the mute output is switched back to the inactive state. when there is the on-hook dialling is not selected and the microphone mute flag in eeprom is high, every press off the m-key will result in the inverted value of the rvol2/lse output. at off-hook the status of this output is high. 5.5.8 o n - hook dialling control if required, the on-hook dialling control feature can be selected by programming the corresponding bit in eeprom. when this on-hook dialling feature is selected, the power supply to the pcd3330-1 must be maintained during on-hook. in telephone sets developed for on-hook dialling (an electronic hook-switch must be present) activation of the hook-key during on-hook results in an off-hook via the dp/ fl output, and the lse output becomes high. as long as the handset stays on the cradle a new activation of the hook-key results in an on-hook, and the lse output becomes low. when during on-hook dialling the handset is lifted from the cradle the on-hook dialling mode is switched off and the lse output is set to the active (low) state. when the handset is off-hook (not on the cradle) activation of this hook-key switches the loudspeaker on (lse = high) or off (lse = low) (listening-in feature). 5.6 number storage, transmission and redial 5.6.1 n umber storage and transmission if the first key pressed at off-hook is 0 to 9 in pulse dialling or 0 to 9, * and # in dtmf dialling mode, digits are entered into the work register and compared with the previous entries stored in the redial register. as long as the newly dialled digits are equal to those stored, the contents of the redial register are unaffected. when the newly pressed digit is different from the one stored in the redial register the contents of the work register are copied to the redial register when going on-hook (or every other action equal to on-hook). up to 24 digits can be stored in the redial register. after the work register overflows, a 10 digits first-in-first-out register (fifo) takes over as buffer and the contents of the work register is now copied to the redial register. after transmitting the first digit of the fifo register this position is automatically cleared to provide space for the storage of new data. in this way, the total number that can be transmitted is unlimited, provided the key-in rate is not excessive. however, if the fifo register overflows (more than 10 digits in store) further input is ignored. input digits are transmitted immediately with minimum transmission time. transmission continues for as long as digits are input. 5.6.2 l ast number redial (1 to 24 digits ) if the first key pressed and released is lnr, the stored number in the redial register is recalled and transmitted immediately. the lnr key can be used in two other ways, known as the cursor method and the atlanta procedure, to allow external numbers to be redialled from a pabx with an appropriate access pause. 5.6.3 a ccess pause by c ursor method if the first key entered is not lnr but numerical digits, these digits are compared to those held in store. as long as the digits entered equal those stored, the redial register in not cleared and dialling can be continued by pressing the redial key. the already dialled part is not redialled. redial is inhibited as soon an entry is unequal to the digit at the same position held in store. this cursor method allows an access code to be entered and access confirmation tone to be received before an external number is redialled. 5.6.4 a ccess pause by a tlanta procedure if the first key entered is the redial key, but this key is kept down, then only the first digit held in the redial register is transmitted. after releasing the redial key the remaining digits held in the redial register are dialled. the atlanta procedure allows a single stored access digit to be transmitted, but redial of the external number to be delayed until access has been confirmed. 5.6.5 10- number repertory dialling the pcd3330-1 includes a 10-number repertory dialler, 16 or 20 digits each, which is accessible with a one or two-key procedure.
1997 jan 15 19 philips semiconductors product speci?cation multistandard repertory dialler/ringer with eeprom pcd3330-1 the 10 repertory numbers can be recalled with the m0 to m9 keys or by pressing the mem key followed by a numeric digit from 0 to 9. if the keyboard matrix contains the keys m0 to m9, each of the 10 repertory numbers can be recalled using the corresponding single key. if the keyboard matrix contains the mem key each of the 10 repertory numbers can be recalled by depressing mem followed by the numeric digit 0 to 9. the maximum length of these repertory numbers is 16 or 20 digits (depending on the programmed repertory number length) including the manually stored access pauses. 5.6.5.1 chain dialling repertory numbers can be dialled-out after or before entering manual dialling or last number redial and by entering the memory locations in successive order (chain dialling). during transmission of a number recalled from the memory location, the controller does not accept keyboard entries. dialling can be continued as soon as the number under transmission is completed. note that the last memory location which is transmitted is stored in the redial register. 5.6.6 3- number repertory dialling when the repertory length programmed in eeprom is set to 16 digits, the pcd3330-1 includes also an additional 3-number repertory dialler. these repertory numbers are only accessible with the one-key procedure. these 3 repertory numbers can only be recalled with the e-1 to e-3 keys. the maximum length of these repertory numbers is 16 digits including the manually stored access pauses. the chain dialling procedure is equal to that explained in 10-number repertory dialling. 5.6.7 a ccess pause storage if during entering a telephone number via keyboard for normal dialling or during repertory number programming the ap-key (access pause key) is pressed, then an access pause is stored in the redial or repertory dial register. 5.6.8 m anual access pauses the ap-key is used to insert an access pause during manual dialling. it is possible to select between four possible access pause times for each dialling mode: for pulse dialling 1.5, 2.5, 3.0 or 6.0 s (inter-digit pause not included). for dtmf dialling 1.0,1.5, 3.5 or 6.0 s (inter-digit pause not included). 5.6.9 s toring repertory numbers when the keytone active bit in eeprom is high, every key activation in programming mode will result in a keytone of 1046 hz lasting 200 ms. the store mode starts after going off-hook and depressing the sto-key. with the pcd3330-1 a selection can be made between two store modes, the general and the german. repertory numbers can be stored into eeprom via the one-key access or the two-key access method and following the german or general storing procedures. this is detailed in tables 5 and 6. table 5 one-key access repertory number mode (m0 to m9 and e-1 to e-3) general procedure german procedure set in operation mode set in operation mode depress sto (store key) depress sto (store key) telephone number location (m0 to m9/e-1 to e-3) depress sto (store key) telephone number location (m0 to m9/e-1 to e-3) sto (store key)

1997 jan 15 28 philips semiconductors product speci?cation multistandard repertory dialler/ringer with eeprom pcd3330-1 11 soldering 11.1 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. 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 dip 11.2.1 s oldering 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. 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 (t stg 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 r epairing 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 so 11.3.1 r eflow 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 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 w ave soldering 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 r epairing 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.
