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 TJA1041 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. 7.1 Operating modes The TJA1041 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 4 shows the conditions for selecting these modes. Figure 3 illustrates the mode transitions when VCC, VI/O and VBAT are present. Operating mode selection[1] Table 4.

[2] Setting the pwon flag or the wake-up flag will clear the UVNOM flag. [3] 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). [4] 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. [5] On entering normal mode the pwon flag and the wake-up flag will be cleared. TJA1041_6 Product data sheet normal (c) NXP B.V. 2007. All rights reserved.

Mode transitions when VCC, VI/O and VBAT are present 7.1.1 Normal mode Normal mode is the mode for normal bidirectional 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 Figure 4) will be active too. 7.1.2 Pwon/listen-only mode In pwon/listen-only mode the transmitter of the transceiver is disabled, effectively providing a transceiver listen-only behavior. 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. TJA1041_6 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 06 -- 5 December 2007 6 of 26 TJA1041 NXP Semiconductors High speed CAN transceiver 7.1.3 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. Pins RXD and ERR will reflect any wake-up requests (provided that VI/O and VCC are present). 7.1.4 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. 7.1.5 Sleep mode The Sleep mode is the second-level power saving mode of the transceiver. Sleep mode is entered via the go-to-sleep 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. 7.2 Internal flags The TJA1041 makes use of seven internal flags for its fail-safe fallback mode control and system diagnosis support. Table 4 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 5 shows the details on how to access these flags. The following sections describe the seven internal flags. Table 5. Accessing internal flags via pin ERR Internal flag Flag is available on pin ERR[1] Flag is cleared UVNOM no by setting the pwon or wake-up flag UVBAT no when VBAT has recovered pwon in pwon/listen-only mode (coming from Standby mode, go-to-sleep command mode, or Sleep mode) on entering normal mode wake-up in Standby mode, go-to-sleep command mode, and Sleep mode (provided that VI/O and VCC are present) on entering normal mode, or by setting the pwon or UVNOM flag TJA1041_6 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 06 -- 5 December 2007 7 of 26 TJA1041 NXP Semiconductors High speed CAN transceiver Table 5. Accessing internal flags via pin ERR ...continued Internal flag Flag is available on pin ERR[1] wake-up source in normal mode (before the fourth dominant to on leaving normal mode, or by recessive edge on pin TXD[2]) setting the pwon flag bus failure in normal mode (after the fourth dominant to recessive edge on pin TXD[2] on re-entering normal mode local failure in pwon/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) Flag is cleared [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. 7.2.1 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. 7.2.2 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. 7.2.3 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. 7.2.4 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 when the bus remains in dominant state for at least tBUS. 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 TJA1041_6 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 06 -- 5 December 2007 8 of 26 TJA1041 NXP Semiconductors High speed CAN transceiver cleared. The wake-up flag is immediately available on pins ERR and RXD (provided 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. 7.2.5 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. 7.2.6 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. 7.2.7 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 overtemperature. The nature and detection of these local failures is described in Section 7.3 "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. 7.3 Local failures The TJA1041 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. 7.3.1 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). 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. 7.3.2 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. TJA1041_6 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 06 -- 5 December 2007 9 of 26 TJA1041 NXP Semiconductors High speed CAN transceiver 7.3.3 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. 7.3.4 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. 7.3.5 Overtemperature detection To protect the output drivers of the transceiver against overheating, the transmitter will be disabled if the virtual junction temperature exceeds the shutdown junction temperature Tj(sd). The transmitter remains disabled until the local failure flag is cleared. 7.4 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 EME. Using pin SPLIT of the TJA1041 in combination with split termination (see Figure 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. 7.5 I/O level adapter The TJA1041 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. 7.6 Pin WAKE Pin WAKE of the TJA1041 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 TJA1041_6 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 06 -- 5 December 2007 10 of 26 TJA1041 NXP Semiconductors High speed CAN transceiver 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. 8. Limiting values Table 6.

Soldering This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 "Surface mount reflow soldering description". 15.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering 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. 15.2 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 probability 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, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus PbSn soldering 15.3 Wave soldering Key characteristics in wave soldering are: * Process issues, such as application of adhesive 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 TJA1041_6 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 06 -- 5 December 2007 21 of 26 TJA1041 NXP Semiconductors High speed CAN transceiver 15.4 Reflow soldering Key characteristics in reflow soldering are: * Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 12) than a PbSn 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 includes 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 Table 10 and 11 Table 10. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 < 2.5 235 220 2.5 220 220 Table 11.
