nxp b.v. 2013. all rights reserved. product data sheet rev. 3 ? 24 april 2013 7 of 27 nxp semiconductors tja1043 high-speed can transceiver 7.1.3 standby mode standby mode is the tja1043?s first-level power saving mode, offering reduced current consumption. in standby mode, the transceiver is unable to transmit or receive data and the low-power receiver is activated to monito r bus activity. the bus pins are biased at ground level (via r i ). pin inh is still active, so voltage regulators controlled by this pin will also be active. pins rxd and err_n will reflect any active wake-up requests (provided that v io and v bat are present). 7.1.4 go-to-sleep mode go-to-sleep mode is the controlled route fo r entering sleep mode. in go-to-sleep mode, the transceiver behaves as in standby mode, with the addition that a go-to-sleep command is issued to the transceiver. the transceiver will remain in go-to-sleep mode for the minimum hold time (t h(min) ) before entering sleep mode. the transceiver will not enter sleep mode if the state of pin stb_n or pin en is changed or if the wake flag is set before t h(min) has elapsed. 7.1.5 sleep mode sleep mode is the tja1043?s second-level power saving mode. sleep mode is entered via go-to-sleep mode, and also when the undervoltage detection time on either v cc or v io elapses before the relevant voltage level has recovered. in sleep mode, the transceiver behaves as described for standby mo de, with the exception that pin inh is set floating. voltage regulators controlled by this pin will be switched off, and the curr ent into pin v bat will be reduced to a minimum. pins stb_n, en and the wake flag can be used to wake up a node from sleep mode (see table 4 ). 7.2 internal flags the tja1043 makes use of seven internal flag s for its fail-safe fallb ack mode control and system diagnosis support. five of these fl ags can be polled by the controller via pin err_n. which flag is available on pin er r_n at any time depends on the active operating mode and on a number of other conditions. table 5 describes how to access these flags. table 5. accessing intern al flags via pin err_n internal flag flag is available on pin err_n [1] flag is cleared uv nom no by setting the pwon or wake flags, by a low-to-high transition on stb_n or when both v io and v bat have recovered. uv bat no when v bat has recovered pwon in listen-only mode (coming from standby mode, go-to-sleep mode, or sleep mode) on entering normal mode wake in standby mode, go-to-sleep mode, and sleep mode (provided that v io and v bat are present) on entering normal mode or by setting the uv nom flag tja1043 all information provided in this document is subject to legal disclaimers. ?

s after changing operating modes. [2] allow for a txd dominant time of at least 4 ? s per dominant-recessive cycle. 7.2.1 uv nom flag uv nom is the v cc and v io undervoltage detection flag. the flag is set when the voltage on pin v cc drops below the v cc undervoltage detection voltage, v uvd(vcc) , for longer than the undervoltage detection time, t det(uv) , or when the voltage on pin v io drops below v uvd(vio) for longer than t det(uv) . when the uv nom flag is set, the transceiver enters sleep mode to save power and to ensure the bus is not disturbed. in sleep mode the voltage regulators connected to pin inh are disabled, avoiding any extra power consumption that might be generated as a result of a short-circuit condition. any wake-up request, settin g the pwon flag or a low-to-h igh transition on stb_n will clear uv nom and the timers, allowing the voltage regulators to be reactivated (at least until uv nom is set again). uv nom will also be cleared if both v cc and v io recover for longer than the undervoltage recovery time, t rec(uv) . the transceiver will then switch to the operating mode indicated by the logic levels on pins stb_n and en (see ta b l e 4 ). 7.2.2 uv bat flag uv bat is the v bat undervoltage detection flag. this flag is set when the voltage on pin v bat drops below v uvd(vbat) . when uv bat is set, the transceiv er will try to enter standby mode to save power and will disengage from the bus (zero load). uv bat is cleared when the voltage on pin v bat recovers. the transceiver will then switch to the operating mode indicated by the logic levels on pins stb_n and en (see ta b l e 4 ). 7.2.3 pwon flag pwon is the v bat power-on flag. this flag is set when the voltage on pin v bat recovers after previously dropping below v uvd(vbat) (usually because the battery was disconnected). setting the pwon flag clears the uv nom flag and timers. the wake and wake-up source flags are set to ensure c onsistent system power-up under all supply conditions. in listen-only mode the pwon flag can be polled via pin err_n (see ta b l e 5 ). the flag is cleared when the transceiver enters normal mode. 7.2.4 wake flag the wake flag is set when the transceiver detects a local or remote wake-up request. a local wake-up request is dete cted when the logic level on pin wake changes, and the new level remains stable for at least t wake . a remote wake-up request is triggered by two bus dominant states of at least t wake(busdom) , with the first dominant state followed by a wake-up source in normal mode (before the fourth dominant-to-recessive edge on pin txd [2] ) on leaving normal mode bus failure in normal mode (after the fourth dominant-to-recessive edge on pin txd [2] ) on re-entering normal mode or by setting the pwon flag local failure in listen-only mode (coming from normal mode) on entering normal mode or when rxd is dominant while txd is recessive (provided that all local failures are resolved) or by setting the pwon flag table 5. accessing intern al flags via pin err_n ?continued internal flag flag is available on pin err_n [1] flag is cleared tja1043 all information provided in this document is subject to legal disclaimers. ?

nxp b.v. 2013. all rights reserved. product data sheet rev. 3 ? 24 april 2013 10 of 27 nxp semiconductors tja1043 high-speed can transceiver 7.3.3 bus dominant clamping detection a can bus short circuit (to v bat , v cc or gnd) or a failure in one of the other network nodes could result in a differential voltage on the bus high enough to represent a bus dominant state. because a node will not start transmission if the bus is dominant, the normal bus failure detection w ill not detect this failure, but the bus dominant clamping detection will. the local failure flag is set if the dominant state on the bus persists for longer than t to(dom)bus . by checking this flag, the contro ller can determine if a clamped bus is blocking network communications. there is no need to disable the transmitter. note that the local failure flag does not retain a bus dominant clamping failure, and is released as soon as the bus returns to recessive state. 7.3.4 overtemperature detection if the junction temperature becomes excessive, the transmitter will shut down in time to protect the output drivers from overheating without compromising the maximum operating temperature. the tran smitter will remain disabled until the local failure flag has been cleared. 7.4 split pin using the split pin on the tja1043 in conjunc tion with a split termination network (see figure 5 and figure 7 ) 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 and listen-only modes, pin split delivers a dc output voltage of 0.5v cc . in standby, go-to-sleep and sleep modes, pin split is floating. 7.5 v io supply pin pin v io should be connected to the microcontroller supply voltage (see figure 7 ). this will cause the signal levels of pins txd, rxd, st b_n, en and err_n to be adjusted to the i/o levels of the microcontrolle r, facilitating direct interfac ing without the need for glue logic. fig 5. stabilization circuit and application gnd v cc v split = 0.5v cc in normal mode and pwon/listen-only mode; otherwise floating tja1043 split 60 60 r r 015aaa064 v split canh canl tja1043 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: tja1043 all information provided in this document is subject to legal disclaimers. ? nxp b.v. 2013. all rights reserved. product data sheet rev. 3 ? 24 april 2013 22 of 27 nxp semiconductors tja1043 high-speed can transceiver ? process issues, such as application of adhe sive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave ? 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 12 ) 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 1 0 and 11 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 12 . table 10. snpb eutectic process (from j-std-020d) package thickness (mm) package reflow temperature ( ?c) volume (mm 3 ) < 350 ?
