FUNCTIONAL DESCRIPTION
7.3
Chip enable (CE)
References to `the device' apply to both the PCD3310 and the PCD3310A. 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). 7.2 Clock oscillator (OSCI and OSCO)
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. 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.
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.

Pulse and DTMF diallers with redial
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. 7.4 7.4.1 Mode selection (PD/DTMF) PULSE MODE

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.
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. 7.4.2 DTMF MODE

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. 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). 7.4.3 MIXED MODE

KEYBOARD
Fig.4 Keyboard organization.
ROW 5 of the keyboard contains the following function keys: * P = memory clear and programming (notepad) * FL = flash or register recall * R = redial * > = 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. In the mixed mode all key entries are valid and executed accordingly.
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. 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. 7.5 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 1996 Nov 21 8

7.6 Flash duration control (FLD)
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. 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.
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. 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 12VDD.

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. 7.10 Mute output (M1)
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. 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. Each entry is tested for validity before being stored in the redial registers. * For DTMF dialling all dial keys are valid * For pulse dialling only numeric dial keys are valid. 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.

8.2 Redialling
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: * Power-on reset * Memory clear (`P' without subsequent data entry) * Memory overflow (more than 23 valid data entries). 8.3 Notepad
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. 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). 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.
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.

15 SOLDERING 15.1 Introduction
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. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. 15.3.2 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). 15.2 15.2.1 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. 15.3.3 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. 15.2.2 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. 15.3 15.3.1 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.
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.
