the tja1042t is 100 % backwards compatib le with the tja1040, and also covers existing pca82c250 and pca82c251 applications ? the tja1042t/3 and tja1042tk/3 allow for direct interfacing to microcontrollers with supply voltages down to 3 v 7.1 operating modes the tja1042 supports two operating modes, no rmal and standby, which are selected via pin stb. see ta b l e 4 for a description of the operating modes under normal supply conditions. 7.1.1 normal mode a low level on pin stb selects normal mode. in this mode, the transceiver can transmit and receive data via the bus lines canh and canl (see figure 1 for the block diagram). the differential receiver converts the analog dat a on the bus lines into digital data which is output to pin rxd. the slope of the output signals on the bus lines is controlled and optimized in a way that guara ntees the lowest possible eme. 7.1.2 standby mode a high level on pin stb selects standby mode . in standby mode, the transceiver is not able to transmit or correctly receive data via the bus lines. the transmitter and normal-mode receiver blocks are switched off to reduce supply current, and only a low-power differential receiver monitors the bu s lines for activity. the wake-up filter on the output of the low-power receiver does not latch bus dominant states, but ensures that only bus dominant and bus recessive states that persist longer than t fltr(wake)bus are reflected on pin rxd. in standby mode, the bus lines are biased to ground to minimize the system supply current. the low-power re ceiver is supplied by v io , and is capable of detecting can bus activity even if v io is the only supply voltage available. when pin rxd goes low to signal a wake-up request, a transition to normal mode will not be trig gered until stb is forced low. table 4. operating modes mode pin stb pin rxd low high normal low bus dominant bus recessive standby high wake-up request detected no wake-up request detected tja1042 all information provided in this document is subject to legal disclaimers. ?

timer is started w hen pin txd is set low. if the low state on pin txd persists for longer than t to(dom)txd , the transmitter is disabled, releasing the bus lines to recessive state. this function prev ents a hardware and/or software application failure from driving the bus lines to a permanent dominant state (blocking all network communications). the txd dominant time-out ti mer is reset when pin txd is set to high. the txd dominant time-out time also defines the minimum possible bit rate of 40 kbit/s. 7.2.2 bus dominant time-out function in standby mode a 'bus dominant time-out' timer is started when the can bus changes from recessive to dominant state. if the domina nt state on the bus persists for longer than t to(dom)bus , the rxd pin is reset to high. this f unction prevents a clamped dominant bus (due to a bus short-circuit or a failure in one of the other nodes on the network) from generating a permanent wake-up request. the bus dominant time-out timer is reset when the can bus changes from dominant to recessive state. 7.2.3 internal biasing of txd and stb input pins pins txd and stb have internal pull-ups to v io to ensure a safe, defined state in case one or both of these pins are left floating. pull- up currents flow in these pins in all states; both pins should be held high in standby mode to minimize standby current. 7.2.4 undervoltage detection on pins v cc and v io should v cc drop below the v cc undervoltage detection level, v uvd(vcc) , the transceiver will switch to standby mode. the logic st ate of pin stb will be ignored until v cc has recovered. should v io drop below the v io undervoltage detection level, v uvd(vio) , the transceiver will switch off and disengage from the bus (zero load) until v io has recovered. 7.2.5 overtemperature protection the output drivers are protected against overte mperature conditions. if the virtual junction temperature exceeds the shutdo wn junction temperature, t j(sd) , the output drivers will be disabled until the virtual junction temperature falls below t j(sd) and txd becomes recessive again. including the txd condition en sures that output driv er oscillation due to temperature drift is avoided. 7.3 split output pin and v io supply pin two versions of the tja1042 are available, only differing in the function of a single pin. pin 5 is either a split output pin or a v io supply pin. 7.3.1 split pin using the split pin on the tja1042t in conjun ction with a split termination network (see figure 3 and figure 6 ) can help to stabilize the recessive voltage level on the bus. this will reduce eme in networks with dc leakage to ground (e.g. from deactivated nodes with poor bus leakage performance). in normal mode, pin split delivers a dc output voltage of 0.5v cc . in standby mode or when v cc is off, pin split is floating. tja1042 all information provided in this document is subject to legal disclaimers. ?

. 16.1 introduction to soldering soldering is one of the most common methods through which packages are attached to printed circuit boards (pcbs), to form electr ical circuits. the soldered joint provides both the mechanical and the electrical connection. th ere is no single sold ering method that is ideal for all ic packages. wave soldering is often preferred when through-hole and surface mount devices (smds) are mixed on one printed wiring board; however, it is not suitable for fine pitch smds. reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 16.2 wave and reflow soldering wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. the wave soldering process is suitable for the following: ? through-hole components ? leaded or leadless smds, which are glued to the surface of the printed circuit board not all smds can be wave soldered. packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. also, leaded smds with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased pr obability of bridging. the reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. leaded packages, packages with solder balls, and leadless packages are all reflow solderable. key characteristics in both wave and reflow soldering are: ? board specifications, in cluding the board finish , solder masks and vias ? package footprints, including solder thieves and orientation ? the moisture sensitivit y level of the packages ? package placement ? inspection and repair ? lead-free soldering versus snpb soldering 16.3 wave soldering key characteristics in wave soldering are: tja1042 all information provided in this document is subject to legal disclaimers. ?

solder bath specifications, including temperature and impurities 16.4 reflow soldering key characteristics in reflow soldering are: ? lead-free versus snpb solderi ng; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see figure 10 ) than a snpb process, thus reducing the process window ? solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board ? reflow temperature profile; this profile includ es preheat, reflow (in which the board is heated to the peak temperature) and cooling down. it is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). in addition, the peak temperature must be low enough that the packages and/or boards are not damaged. the peak temperature of the package depends on package thickness and volume and is classified in accordance with ta b l e 9 and 10 moisture sensitivity precautions, as indicat ed on the packing, must be respected at all times. studies have shown that small packages reach higher temperatures during reflow soldering, see figure 10 . table 9. snpb eutectic process (from j-std-020c) package thickness (mm) package reflow temperature ( ?c) volume (mm 3 ) < 350 ?
