TJA1043 High-speed CAN transceiver Rev. 2 -- 20 June 2011 Product data sheet 1. General description The TJA1043 is a high-speed CAN transceiver that provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed (up to 1 Mbit/s) CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJA1043 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1041A. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroMagnetic Discharge (ESD) performance, very low power consumption, and passive behavior when the supply voltage is turned off. Advanced features include: * Low-power management controls the power supply throughout the node while supporting local and remote wake-up with wake-up source recognition * Several protection and diagnostic functions including bus line short-circuit detection and battery connection detection * Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V These features make the TJA1043 the ideal choice for high speed CAN networks containing nodes that need to be available all times, even when the internal VIO and VCC supplies are switched off. 2.

Control pins STB_N and EN are used to select the operating mode. Switching between modes allows access to a number of diagnostics flags via pin ERR_N. Table 4 describes how to switch between modes. Figure 3 illustrates the mode transitions when VCC, VIO and VBAT are valid. Table 4.

The differential receiver converts the analog data 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 guarantees the lowest possible EME. The bus pins are biased to 0.5VCC (via Ri). Pin INH is active, so voltage regulators controlled by pin INH (see Figure 6) will be active too. 7.1.2 Listen-only mode In Listen-only mode, the transceiver's transmitter is disabled, effectively providing a transceiver listen-only feature. The receiver will still convert the analog bus signal on pins CANH and CANL into digital data, available for output on pin RXD. As in Normal mode, the bus pins are biased at 0.5VCC and pin INH remains active. TJA1043 Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 6 of 26 TJA1043 NXP Semiconductors 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 monitor bus activity. The bus pins are biased at ground level (via Ri). 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 VIO and VBAT are present). 7.1.4 Go-to-Sleep mode Go-to-Sleep mode is the controlled route for 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 (th(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 th(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 VCC or VIO elapses before the relevant voltage level has recovered. In Sleep mode, the transceiver behaves as described for Standby mode, with the exception that pin INH is set floating. Voltage regulators controlled by this pin will be switched off, and the current into pin VBAT 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 flags for its fail-safe fallback mode control and system diagnosis support. Five of these flags can be polled by the controller via pin ERR_N. Which flag is available on pin ERR_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. TJA1043 Product data sheet Accessing internal flags via pin ERR_N Internal flag Flag is available on pin ERR_N[1] Flag is cleared UVNOM no by setting the Pwon or Wake flags, by a LOW-to-HIGH transition on STB_N or when both VIO and VBAT have recovered. UVBAT no when VBAT has recovered Pwon in Listen-only mode (coming from Standby on entering Normal mode mode, Go-to-Sleep mode, or Sleep mode) Wake in Standby mode, Go-to-Sleep mode, and Sleep mode (provided that VIO and VBAT are present) All information provided in this document is subject to legal disclaimers.

Accessing internal flags via pin ERR_N ...continued Internal flag Flag is available on pin ERR_N[1] Wake-up source in Normal mode (before the fourth on leaving Normal mode dominant-to-recessive edge on pin TXD[2]) Bus failure on re-entering Normal mode or by in Normal mode (after the fourth dominant-to-recessive edge on pin TXD[2]) setting the Pwon flag Local failure in Listen-only mode (coming from Normal mode) Flag is cleared 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 [1] Pin ERR_N is an active-LOW output, so a LOW-level indicates a set flag and a HIGH-level indicates a cleared flag. Allow pin ERR_N 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 VIO undervoltage detection flag. The flag is set when the voltage on pin VCC drops below the VCC undervoltage detection voltage, Vuvd(VCC), for longer than the undervoltage detection time, tdet(uv), or when the voltage on pin VIO drops below Vuvd(VIO) for longer than tdet(uv). When the UVNOM 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, setting the Pwon flag or a LOW-to-HIGH transition on STB_N will clear UVNOM and the timers, allowing the voltage regulators to be reactivated (at least until UVNOM is set again). UVNOM will also be cleared if both VCC and VIO recover for longer than the undervoltage recovery time, trec(uv). The transceiver will then switch to the operating mode indicated by the logic levels on pins STB_N and EN (see Table 4). 7.2.2 UVBAT flag UVBAT is the VBAT undervoltage detection flag. This flag is set when the voltage on pin VBAT drops below Vuvd(VBAT). When UVBAT is set, the transceiver will try to enter Standby mode to save power and will disengage from the bus (zero load). UVBAT is cleared when the voltage on pin VBAT recovers. The transceiver will then switch to the operating mode indicated by the logic levels on pins STB_N and EN (see Table 4). 7.2.3 Pwon flag Pwon is the VBAT power-on flag. This flag is set when the voltage on pin VBAT recovers after previously dropping below Vuvd(VBAT) (usually because the battery was disconnected). Setting the Pwon flag clears the UVNOM flag and timers. The Wake and Wake-up source flags are set to ensure consistent system power-up under all supply conditions. In Listen-only mode the Pwon flag can be polled via pin ERR_N (see Table 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 detected when the logic level on pin WAKE changes, and the new level remains stable for at least twake. A remote wake-up request is triggered by two bus dominant states of at least twake(busdom), with the first dominant state followed by a TJA1043 Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 2 -- 20 June 2011 (c) NXP B.V. 2011. All rights reserved. 8 of 26 TJA1043 NXP Semiconductors High-speed CAN transceiver recessive state of at least twake(busrec) (provided the complete dominant-recessive-dominant pattern is completed within tto(wake)bus). The Wake flag can be set in Standby mode, Go-to-Sleep mode or Sleep mode. Setting the Wake flag clears the UVNOM flag and timers. Once set, the Wake flag status is immediately available on pins ERR_N and RXD (provided VIO and VBAT are present). This flag is also set at power-on and cleared 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 flag is set by a local wake-up request via the WAKE pin. The Wake-up source flag can be polled via the ERR_N pin in Normal mode (see Table 5). This flag is also set at power-on and cleared 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, while trying to drive the bus lines dominant. The Bus failure flag can be polled via the ERR_N pin in Normal mode (see Table 5). This flag is cleared at power-on or when the transceiver re-enters Normal mode. 7.2.7 Local failure flag In Normal and Listen-only modes, the transceiver can distinguish four different local failure events, any of which will cause the Local failure flag to be set. The four local failure events are: TXD dominant clamping, TXD-to-RXD short circuit, bus dominant clamping and an overtemperature event. The nature and detection of these local failures is described in Section 7.3. The Local failure flag can be polled via the ERR_N pin in Listen-only mode (see Table 5). This flag is cleared at power-on, when entering Normal mode or when RXD is dominant while TXD is recessive, provided that all local failures have been resolved. 7.3 Local failures The TJA1043 can detect four 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. 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 communications. The TXD dominant time-out function prevents such a network lock-up by disabling the transmitter if pin TXD remains LOW for longer than the TXD dominant time-out time tto(dom)TXD. The tto(dom)TXD timer defines the minimum possible bit rate of 40 kbit/s. The transmitter remains disabled until the Local failure flag has been cleared. 7.3.2 TXD-to-RXD short-circuit detection A short-circuit between pins RXD and TXD would lock the bus in a permanent dominant state once it had been driven dominant, because the low-side driver of RXD is typically stronger than the high-side driver of the controller connected to TXD. 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 has been cleared.

All rights reserved. 9 of 26 TJA1043 NXP Semiconductors High-speed CAN transceiver 7.3.3 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 tto(dom)bus. By checking this flag, the controller 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 transmitter will remain disabled until the Local failure flag has been cleared. 7.4 SPLIT pin Using the SPLIT pin on the TJA1043 in conjunction with a split termination network (see Figure 4 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 and Listen-only modes, pin SPLIT delivers a DC output voltage of 0.5VCC. In Standby, Go-to-Sleep and Sleep modes, pin SPLIT is floating. VCC TJA1043 CANH VSPLIT = 0.5VCC in normal mode and pwon/listen-only mode; otherwise floating 60 R VSPLIT SPLIT 60 R CANL GND 015aaa064 Fig 4. Stabilization circuit and application 7.5 VIO supply pin Pin VIO should be connected to the microcontroller supply voltage (see Figure 6). This will cause the signal levels of pins TXD, RXD, STB_N, EN and ERR_N to be adjusted to the I/O levels of the microcontroller, facilitating direct interfacing without the need for glue logic.

All rights reserved. 10 of 26 TJA1043 NXP Semiconductors High-speed CAN transceiver 7.6 WAKE pin A local wake-up event is triggered by a LOW-to-HIGH or HIGH-to-LOW transition on the WAKE pin, allowing for maximum flexibility when designing a local wake-up circuit.To minimize current consumption, the internal bias voltage will follow the logic state on the pin after a delay of twake. 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. In applications that don't make use of the local wake-up facility, it is recommended that the WAKE pin be connected to VBAT or GND to ensure optimal EMI performance.

Handling information All input and output pins are protected against ElectroStatic Discharge (ESD) under normal handling. When handling ensure that the appropriate precautions are taken as described in JESD625-A or equivalent standards. 16. Soldering of SMD packages 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". 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 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. 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 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 SnPb soldering 16.3 Wave soldering Key characteristics in wave soldering are: TJA1043 Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 2 -- 20 June 2011 (c) NXP B.V. 2011. All rights reserved. 20 of 26 TJA1043 NXP Semiconductors High-speed CAN transceiver * 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 16.4 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 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 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.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 10.
