1. General description
The TJA1043 high-speed CAN transceiver 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 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 ElectroStatic 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
The TJA1043 implements the CAN physical layer as defined in ISO 11898-2:2016 and
SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the
CAN FD fast phase at data rates up to 5 Mbit/s.
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.

NXP Semiconductors TJA1043
High-speed CAN transceiver
7.1.1 Normal mode
In Normal 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 data on the bus lines into digital data which is output to pin RXD. The slopes of the
output signals on the bus lines are controlled internally and are 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 9) 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.

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 second-level power saving mode of the TJA1043. 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.

NXP Semiconductors TJA1043
High-speed CAN transceiver
[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. 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 Remote wake-up (via the CAN bus)
The TJA1043 wakes up from Standby or Sleep mode when a dedicated wake-up pattern
(specified in ISO 11898-2: 2016) is detected on the bus. This filtering helps avoid spurious
wake-up events. A spurious wake-up sequence could be triggered by, for example, a
dominant clamped bus or by dominant phases due to noise or spikes on the bus.
The wake-up pattern consists of:
a dominant phase of at least twake(busdom) followed by
a recessive phase of at least twake(busrec) followed by
a dominant phase of at least twake(busdom)
Dominant or recessive bits between the above mentioned phases that are shorter than
twake(busdom) and twake(busrec) respectively are ignored.
The complete dominant-recessive-dominant pattern must be received within tto(wake)bus to
be recognized as a valid wake-up pattern (see Figure 5). Otherwise, the internal wake-up
logic is reset. The complete wake-up pattern will then need to be retransmitted to trigger a
wake-up event. Pin RXD remains HIGH until the wake-up event has been triggered.
A wake-up event is not flagged on RXD if any of the following events occurs while a valid
wake-up pattern is being received:
The TJA1043 switches to Normal mode
The complete wake-up pattern was not received within tto(wake)bus
A VCC or VIO undervoltage is detected (UVNOM flag set; see Section 7.2.1)
7.2.6 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.

NXP Semiconductors TJA1043
High-speed CAN transceiver
7.2.7 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.
7.2.8 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 time-out function
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.
7.3.3 Bus dominant time-out function
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.

High-speed CAN transceiver
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 6 and Figure 9) 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.
7.5 VIO supply pin
Pin VIO should be connected to the microcontroller supply voltage (see Figure 9). 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.
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.

15. 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:

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 15) 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
Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 15.
