FUNCTIONAL DESCRIPTION The primary function of a CAN transceiver is to provide the CAN physical layer as described in the ISO 11898 standard. In the TJA1041A this primary function is complemented with a number of operating modes, fail-safe features and diagnosis features, which offer enhanced system reliability and advanced power management functionality. Operating modes The TJA1041A can be operated in five modes, each with specific features. Control pins STB and EN select the operating mode. Changing between modes also gives access to a number of diagnostics flags, available via pin ERR. The following sections describe the five operating modes. Table 1 shows the conditions for selecting these modes. Figure 3 illustrates the mode transitions when VCC, VI/O and VBAT are present. 2004 Feb 20 5 Philips Semiconductors Product specification High speed CAN transceiver Table 1 Operating mode selection INTERNAL FLAGS OPERATING MODE STB X EN X UVNOM set cleared UVBAT X set pwon, wake-up X(1) one or both set both cleared L L cleared cleared one or both set both cleared L H cleared cleared one or both set both cleared sleep mode; note 2 standby mode no change from sleep mode standby mode from any other mode standby mode no change from sleep mode standby mode from any other mode standby mode no change from sleep mode TJA1041A CONTROL PINS PIN INH floating H floating H H floating H H floating H(3) H H go-to-sleep command mode from any other mode; note 3 H H Notes 1.

The transceiver directly enters sleep mode and pin INH is set floating when the UVNOM flag is set (so after the undervoltage detection time on either VCC or VI/O has elapsed before that voltage level has recovered). 3. When go-to-sleep command mode is selected for longer than the minimum hold time of the go-to-sleep command, the transceiver will enter sleep mode and pin INH is set floating. 4. On entering normal mode the pwon flag and the wake-up flag will be cleared. 2004 Feb 20 6 Philips Semiconductors Product specification High speed CAN transceiver TJA1041A handbook, full pagewidth STB = H and EN = H PWON/LISTENONLY MODE STB = H and EN = L NORMAL MODE STB = H and EN = L STB = L and (EN = L or flag set) STB = H and EN = L STB = H and EN = H STB = H and EN = H STB = L and EN = H STB = L and EN = H and flags cleared STB = L and EN = L STB = L and EN = H and flags cleared STB = L and (EN = L or flag set) STANDBY MODE GO-TO-SLEEP COMMAND MODE STB = H and EN = L and UVNOM cleared STB = L and flag set SLEEP MODE flags cleared and t > t h(min) STB = H and EN = H and UVNOM cleared LEGEND: = H, = L flag set flags cleared logical state of pin setting pwon and/or wake-up flag pwon and wake-up flag both cleared MGU983 Fig.3 Mode transitions when VCC, VI/O and VBAT are present. NORMAL MODE Normal mode is the mode for normal bi-directional CAN communication. The receiver will convert the differential analog bus signal on pins CANH and CANL into digital data, available for output to pin RXD. The transmitter will convert digital data on pin TXD into a differential analog signal, available for output to the bus pins. The bus pins are biased at 0.5VCC (via Ri(cm)). Pin INH is active, so voltage regulators controlled by pin INH (see Fig.4) will be active too. PWON/LISTEN-ONLY MODE In pwon/listen-only mode the transmitter of the transceiver is disabled, effectively providing a transceiver listen-only 2004 Feb 20 7 behaviour. The receiver will still convert the analog bus signal on pins CANH and CANL into digital data, available for output to pin RXD. As in normal mode the bus pins are biased at 0.5VCC, and pin INH remains active. STANDBY MODE The standby mode is the first-level power saving mode of the transceiver, offering reduced current consumption. In standby mode the transceiver is not able to transmit or receive data and the low-power receiver is activated to monitor bus activity. The bus pins are biased at ground level (via Ri(cm)). Pin INH is still active, so voltage regulators controlled by this pin INH will be active too. Philips Semiconductors Product specification High speed CAN transceiver Pins RXD and ERR will reflect any wake-up requests (provided that VI/O and VCC are present). GO-TO-SLEEP COMMAND MODE The go-to-sleep command mode is the controlled route for entering sleep mode. In go-to-sleep command mode the transceiver behaves as if in standby mode, plus a go-to-sleep command is issued to the transceiver. After remaining in go-to-sleep command mode for the minimum hold time (th(min)), the transceiver will enter sleep mode. The transceiver will not enter the sleep mode if the state of pins STB or EN is changed or the UVBAT, pwon or wake-up flag is set before th(min) has expired. SLEEP MODE The sleep mode is the second-level power saving mode of the transceiver. Sleep mode is entered via the go-to-sleep TJA1041A command mode, and also when the undervoltage detection time on either VCC or VI/O elapses before that voltage level has recovered. In sleep mode the transceiver still behaves as described for standby mode, but now pin INH is set floating. Voltage regulators controlled by pin INH will be switched off, and the current into pin VBAT is reduced to a minimum. Waking up a node from sleep mode is possible via the wake-up flag and (as long as the UVNOM flag is not set) via pin STB. Internal flags The TJA1041A makes use of seven internal flags for its fail-safe fallback mode control and system diagnosis support. Table 1 shows the relation between flags and operating modes of the transceiver. Five of the internal flags can be made available to the controller via pin ERR. Table 2 shows the details on how to access these flags. The following sections describe the seven internal flags. Table 2 Accessing internal flags via pin ERR Flag is available on pin ERR(1) no no in pwon/listen-only mode (coming from standby mode, go-to-sleep command mode, or sleep mode) Flag is cleared by setting the pwon or wake-up flag when VBAT has recovered on entering normal mode Internal flag UVNOM UVBAT pwon wake-up wake-up source bus failure local failure in standby mode, go-to-sleep command mode, and on entering normal mode, or by setting the sleep mode (provided that VI/O and VCC are present) pwon or UVNOM flag in normal mode (before the fourth dominant to recessive edge on pin TXD; note 2) in normal mode (after the fourth dominant to recessive edge on pin TXD; note 2) in pwon/listen-only mode (coming from normal mode) on leaving normal mode, or by setting the pwon flag on re-entering normal mode on entering normal mode or when RXD is dominant while TXD is recessive (provided that all local failures are resolved) Notes 1. Pin ERR is an active-LOW output, so a LOW level indicates a set flag and a HIGH level indicates a cleared flag. Allow pin ERR to stabilize for at least 8 s after changing operating modes. 2. Allow for a TXD dominant time of at least 4 s per dominant-recessive cycle. 2004 Feb 20 8 Philips Semiconductors Product specification High speed CAN transceiver UVNOM FLAG UVNOM is the VCC and VI/O undervoltage detection flag. The flag is set when the voltage on pin VCC drops below VCC(sleep) for longer than tUV(VCC) or when the voltage on pin VI/O drops below VI/O(sleep) for longer than tUV(VI/O). When the UVNOM flag is set, the transceiver will enter sleep mode to save power and not disturb the bus. In sleep mode the voltage regulators connected to pin INH are disabled, avoiding the extra power consumption in case of a short-circuit condition. After a waiting time (fixed by the same timers used for setting UVNOM) any wake-up request or setting of the pwon flag will clear UVNOM and the timers, allowing the voltage regulators to be reactivated at least until UVNOM is set again. UVBAT FLAG UVBAT is the VBAT undervoltage detection flag. The flag is set when the voltage on pin VBAT drops below VBAT(stb). When UVBAT is set, the transceiver will try to enter standby mode to save power and not disturb the bus. UVBAT is cleared when the voltage on pin VBAT has recovered. The transceiver will then return to the operating mode determined by the logic state of pins STB and EN. PWON FLAG Pwon is the VBAT power-on flag. This flag is set when the voltage on pin VBAT has recovered after it dropped below VBAT(pwon), particularly after the transceiver was disconnected from the battery. By setting the pwon flag, the UVNOM flag and timers are cleared and the transceiver cannot enter sleep mode. This ensures that any voltage regulator connected to pin INH is activated when the node is reconnected to the battery. In pwon/listen-only mode the pwon flag can be made available on pin ERR. The flag is cleared when the transceiver enters normal mode. WAKE-UP FLAG The wake-up flag is set when the transceiver detects a local or a remote wake-up request. A local wake-up request is detected when a logic state change on pin WAKE remains stable for at least twake. A remote wake-up request is detected after two bus dominant states of at least tBUSdom (with each dominant state followed by a recessive state of at least tBUSrec). The wake-up flag can only be set in standby mode, go-to-sleep command mode or sleep mode. Setting of the flag is blocked during the UVNOM flag waiting time. By setting the wake-up flag, the UVNOM flag and timers are cleared. The wake-up flag is immediately available on pins ERR and RXD (provided TJA1041A that VI/O and VCC are present). The flag is cleared at power-on, or when the UVNOM flag is set or the transceiver enters normal mode. WAKE-UP SOURCE FLAG Wake-up source recognition is provided via the wake-up source flag, which is set when the wake-up flag is set by a local wake-up request via pin WAKE. The wake-up source flag can only be set after the pwon flag is cleared. In normal mode the wake-up source flag can be made available on pin ERR. The flag is cleared at power-on or when the transceiver leaves normal mode. BUS FAILURE FLAG The bus failure flag is set if the transceiver detects a bus line short-circuit condition to VBAT, VCC or GND during four consecutive dominant-recessive cycles on pin TXD, when trying to drive the bus lines dominant. In normal mode the bus failure flag can be made available on pin ERR. The flag is cleared when the transceiver re-enters normal mode. LOCAL FAILURE FLAG In normal mode or pwon/listen-only mode the transceiver can recognize five different local failures, and will combine them into one local failure flag. The five local failures are: TXD dominant clamping, RXD recessive clamping, a TXD-to-RXD short circuit, bus dominant clamping, and over-temperature. Nature and detection of these local failures is described in Section "Local failures". In pwon/listen-only mode the local failure flag can be made available on pin ERR. The flag is cleared when entering normal mode or when RXD is dominant while TXD is recessive, provided that all local failures are resolved. Local failures The TJA1041A can detect five different local failure conditions. Any of these failures will set the local failure flag, and in most cases the transmitter of the transceiver will be disabled. The following sections give the details. TXD DOMINANT CLAMPING DETECTION A permanent LOW level on pin TXD (due to a hardware or software application failure) would drive the CAN bus into a permanent dominant state, blocking all network communication. The TXD dominant time-out function prevents such a network lock-up by disabling the transmitter of the transceiver if pin TXD remains at a LOW level for longer than the TXD dominant time-out tdom(TXD). 2004 Feb 20 9 Philips Semiconductors Product specification High speed CAN transceiver The tdom(TXD) timer defines the minimum possible bit rate of 40 kbit/s. The transmitter remains disabled until the local failure flag is cleared. RXD RECESSIVE CLAMPING DETECTION An RXD pin clamped to HIGH level will prevent the controller connected to this pin from recognizing a bus dominant state. So the controller can start messages at any time, which is likely to disturb all bus communication. RXD recessive clamping detection prevents this effect by disabling the transmitter when the bus is in dominant state without RXD reflecting this. The transmitter remains disabled until the local failure flag is cleared. TXD-TO-RXD SHORT-CIRCUIT DETECTION A short-circuit between pins RXD and TXD would keep the bus in a permanent dominant state once the bus is driven dominant, because the low-side driver of RXD is typically stronger than the high-side driver of the controller connected to TXD. The TXD-to-RXD short-circuit detection prevents such a network lock-up by disabling the transmitter. The transmitter remains disabled until the local failure flag is cleared. BUS DOMINANT CLAMPING DETECTION A CAN bus short circuit (to VBAT, VCC 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 will 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 tdom(bus). By checking this flag, the controller can determine if a clamped bus is blocking network communication. 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. OVER-TEMPERATURE DETECTION To protect the output drivers of the transceiver against overheating, the transmitter will be disabled if the virtual TJA1041A junction temperature exceeds the shutdown junction temperature Tj(sd). The transmitter remains disabled until the local failure flag is cleared. Recessive bus voltage stabilization In recessive state the output impedance of transceivers is relatively high. In a partially powered network (supply voltage is off in some of the nodes) any deactivated transceiver with a significant leakage current is likely to load the recessive bus to ground. This will cause a common-mode voltage step each time transmission starts, resulting in increased ElectroMagnetic Emission (EME). Using pin SPLIT of the TJA1041A in combination with split termination (see Fig.5) will reduce this step effect. In normal mode and pwon/listen-only mode pin SPLIT provides a stabilized 0.5VCC DC voltage. In standby mode, go-to-sleep command mode and sleep mode pin SPLIT is set floating. I/O level adapter The TJA1041A is equipped with a built-in I/O-level adapter. By using the supply voltage of the controller (to be supplied at pin VI/O) the level adapter ratio-metrically scales the I/O-levels of the transceiver. For pins TXD, STB and EN the digital input threshold level is adjusted, and for pins RXD and ERR the HIGH-level output voltage is adjusted. This allows the transceiver to be directly interfaced with controllers on supply voltages between 2.8 V and 5.25 V, without the need for glue logic. Pin WAKE Pin WAKE of the TJA1041A allows local wake-up triggering by a LOW to HIGH state change as well as a HIGH to LOW state change. This gives maximum flexibility when designing a local wake-up circuit. To keep current consumption at a minimum, after a twake delay the internal bias voltage of pin WAKE will follow the logic state of this pin. A HIGH level on pin WAKE is followed by an internal pull-up to VBAT. A LOW level on pin WAKE is followed by an internal pull-down towards GND. To ensure EMI performance in applications not using local wake-up it is recommended to connect pin WAKE to pin VBAT or to pin GND. 2004 Feb 20 10 Philips Semiconductors Product specification High speed CAN transceiver LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 60134).

OUTLINE VERSION SOT108-1 REFERENCES IEC 076E06 JEDEC MS-012 JEITA EUROPEAN PROJECTION ISSUE DATE 99-12-27 03-02-19 2004 Feb 20 19 Philips Semiconductors Product specification High speed CAN transceiver SOLDERING Introduction to soldering surface mount packages 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" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. Reflow soldering 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. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 270 C depending on solder paste material. The top-surface temperature of the packages should preferably be kept: * below 225 C (SnPb process) or below 245 C (Pb-free process) - for all BGA, HTSSON-T and SSOP-T packages - for packages with a thickness 2.5 mm - for packages with a thickness < 2.5 mm and a volume 350 mm3 so called thick/large packages. * below 240 C (SnPb process) or below 260 C (Pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages. Moisture sensitivity precautions, as indicated on packing, must be respected at all times. Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. 2004 Feb 20 20 TJA1041A If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. 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. Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 C or 265 C, depending on solder material applied, SnPb or Pb-free respectively. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron 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. Philips Semiconductors Product specification High speed CAN transceiver Suitability of surface mount IC packages for wave and reflow soldering methods PACKAGE(1) BGA, HTSSON..T(3), LBGA, LFBGA, SQFP, SSOP..T(3), TFBGA, USON, VFBGA DHVQFN, HBCC, HBGA, HLQFP, HSO, HSOP, HSQFP, HSSON, HTQFP, HTSSOP, HVQFN, HVSON, SMS PLCC(5), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO, VSSOP CWQCCN..L(8), PMFP(9), WQCCN..L(8) Notes not suitable not suitable(4) suitable not not recommended(5)(6) recommended(7) TJA1041A SOLDERING METHOD WAVE REFLOW(2) suitable suitable suitable suitable suitable not suitable not suitable 1. For more detailed information on the BGA packages refer to the "(LF)BGA Application Note" (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 C 10 C measured in the atmosphere of the reflow oven. The package body peak temperature must be kept as low as possible. 4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 5. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 6. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. The appropriate soldering profile can be provided on request. 9. Hot bar or manual soldering is suitable for PMFP packages. 2004 Feb 20 21 Philips Semiconductors Product specification High speed CAN transceiver DATA SHEET STATUS LEVEL I DATA SHEET STATUS(1) Objective data PRODUCT STATUS(2)(3) Development DEFINITION TJA1041A This data sheet contains data from the objective specification for product development.
