controlled functions i 2 c-bus speci?cation the standard i 2 c-bus specification is expanded by the following definitions. structure of the i 2 c-bus logic: slave transceiver with auto increment and expansion to switch a direct transfer of all transmissions to an output for the radio front-end ic (tea6810t respectively tea6811t). subaddresses are not used. d ata transfer for the tea6823t and the TEA6825T data sequence: address byte 1 byte 2. the data transfer may be in this order only. the transfer direction of the data bytes is defined by the lsb of the address. the data becomes valid at the output of the internal latches with the acknowledge of each byte. a stop condition after any byte can shorten transmission times. when writing to the transceiver by using the stop condition before completion of the whole transfer: the remaining bytes will contain the old information if the transfer of a byte was not completed, this byte is lost and the previous information is available. d ata transfer to an output of the front - end ic a data bit in the transceiver of the tea6823t or TEA6825T enables or disables a direct transfer of all transmissions to an interface stage for the front-end ic. for a transmission to the front-end ic the address and the data format of the front-end ic has to be used. remark: the pull-up resistors for the front-end interface (pins 6 and 7) should not be connected to the 5 v supply voltage of the front-end ic, otherwise a bus pull-down (pin 53) can occur during switching off the front-end supply when the interface stage is enabled. d ata transfer to the if ic data transfer to the if ic (tea6823t or TEA6825T) is independent of the state of interface stage for the front-end ic. table 1 structure of the i 2 c-bus table 2 data to be received by the

while reading this value. if the transmission to the front-end ic is disabled after the synthesizer loop of the tea6810t/tea6811t front-end ic has locked for a new frequency, the if-count will be

speci?cation in car entertainment (ice) car radio tea6823t; TEA6825T soldering 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 data handbook ic26; integrated circuit packages (order code 9398 652 90011). re?ow soldering reflow soldering techniques are suitable for all vso 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. wave soldering wave soldering techniques can be used for all vso 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. 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. 1998 mar 24 46 philips semiconductors preliminary speci?cation in car entertainment (ice) car radio tea6823t; TEA6825T definitions life support
