GENERAL DESCRIPTION
The TJA1054A is the interface between the protocol
controller and the physical bus wires in a Controller Area
Network (CAN). It is primarily intended for low-speed
applications up to 125 kBaud in passenger cars. The
device provides differential receive and transmit capability
but will switch to single-wire transmitter and/or receiver in
error conditions.
The TJA1054A is the ESD improved version of the
TJA1054. For an overview of the differences between the
TJA1054 and the TJA1054A, please refer to “Appendix A”.
The TJA1054AT is, as the TJA1054T, pin and downwards
compatiblewiththePCA82C252TandtheTJA1053T. This
means that these two devices can be replaced by the
TJA1054AT or the TJA1054T with retention of all
functions.
Themost important improvements of the TJA1054 and the
TJA1054A with respect to the PCA82C252 and the
TJA1053 are:
• Very low EME due to a very good matching of the CANL
and CANH output signals
• Good EMI, especially in low power modes
• Full wake-up capability during bus failures
• Extended bus failure management including
short-circuit of the CANH bus line to V
CC
• Support for easy system fault diagnosis
• Two-edge sensitive wake-up input signal via pin WAKE.
Support for low power modes
• Low current sleep and standby mode with wake-up via
the bus lines
• Power-on reset flag on the output.

Fault-tolerant CAN transceiverTJA1054A
FUNCTIONAL DESCRIPTION
The TJA1054A is the interface between the CAN protocol
controller and the physical wires of the CAN bus (see
Fig.7). It is primarily intended for low-speed applications,
up to 125 kBaud, in passenger cars. The device provides
differential transmit capability to the CAN bus and
differential receive capability to the CAN controller.
To reduce EME, the rise and fall slopes are limited. This
allows the use of an unshielded twisted pair or a parallel
pair of wires for the bus lines. Moreover, the device
supportstransmission capability on either bus line if one of
the wires is corrupted. The failure detection logic
automatically selects a suitable transmission mode.
In normal operating mode (no wiring failures) the
differential receiver is output on pin RXD (see Fig.1).
The differential receiver inputs are connected to
pins CANH and CANL through integrated filters.
The filtered input signals are also used for the single-wire
receivers. The receivers connected to pins CANH
and CANL have threshold voltages that ensure a
maximum noise margin in single-wire mode.
A timer function (TxD dominant time-out function) has
been integrated to prevent the bus lines from being driven
into a permanent dominant state (thus blocking the entire
network communication) due to a situation in which
pin TXD is permanently forced to a LOW level, caused by
a hardware and/or software application failure.
If the duration of the LOW level on pin TXD exceeds a
certain time, the transmitter will be disabled. The timer will
be reset by a HIGH level on pin TXD.
Failure detector
The failure detector is fully active in the normal operating
mode. After the detection of a single bus failure the
detector switches to the appropriate mode (see Table 1).
The differential receiver threshold voltage is set at −3.2 V
typical (VCC= 5 V). This ensures correct reception with a
noise margin as high as possible in the normal operating
mode and in the event of failures 1, 2, 5 and 6a. These
failures, or recovery from them, do not destroy ongoing
transmissions. The output drivers remain active, the
termination does not change and the receiver remains in
differential mode (see Table 1).
Failures 3, 3a and 6 are detected by comparators
connected to the CANH and CANL bus lines.
Failures 3 and 3a are detected in a two-step approach.
If the CANH bus line exceeds a certain voltage level, the
differential comparator signals a continuous dominant
condition. Because of inter operability reasons with the
predecessor products PCA82C252 and TJA1053, after a
first time-out the transceiver switches to single-wire
operation through CANH. If the CANH bus line is still
exceeding the CANH detection voltage for a second
time-out, the TJA1054A switches to CANL operation; the
CANH driver is switched off and the RTH bias changes to
the pull-down current source. The time-outs (delays) are
needed to avoid false triggering by external RF fields.

Failure 6 is detected if the CANL bus line exceeds its
comparator threshold for a certain period of time. This
delay is needed to avoid false triggering by external RF
fields. After detection of failure 6, the reception is switched
to the single-wire mode through CANH; the CANL driver is
switched off and the RTL bias changes to the pull-up
current source.
Recovery from failures 3, 3a and 6 is detected
automatically after reading a consecutive recessive level
by corresponding comparators for a certain period of time.
Failures 4 and 7 initially result in a permanent dominant
level on pin RXD. After a time-out the CANL driver is
switched off and the RTL bias changes to the pull-up
current source. Reception continues by switching to the
single-wire mode via pins CANH or CANL. When
failures 4 or 7 are removed, the recessive bus levels are
restored. If the differential voltage remains below the
recessive threshold level for a certain period of time,
reception and transmission switch back to the differential
mode.
If any of the wiring failure occurs, the output signal on
pin ERR will be set to LOW. On error recovery, the output
signal on pin ERR will be set to HIGH again. In case of an
interrupted open bus wire, this failure will be detected and
signalled only if there is an open wire between the
transmittingand receiving node(s). Thus, during open wire
failures, pin ERR typically toggles.
During all single-wire transmissions, EMC performance
(both immunity and emission) is worse than in the
differential mode. The integrated receiver filters suppress
any HF noise induced into the bus wires. The cut-off
frequency of these filters is a compromise between
propagation delay and HF suppression. In single-wire
mode, LF noise cannot be distinguished from the required
signal.
Low power modes
The transceiver provides three low power modes which
can be entered and exited via STB and EN (see Table 2
and Fig.3).
The sleep mode is the mode with the lowest power
consumption. Pin INH is switched to HIGH-impedance for
deactivation of the external voltage regulator. Pin CANL is
biased to the battery voltage via pin RTL. If the supply
voltage is provided, pins RXD and ERR will signal the
wake-up interrupt.
The standby mode operates in the same way as the sleep
mode but with a HIGH level on pin INH.
The power-on standby mode is the same as the standby
mode, however, in this mode the battery power-on flag is
shown on pin ERR instead of the wake-up interrupt signal.
The output on pin RXD will show the wake-up interrupt.
This mode is only for reading out the power-on flag.

Wake-up requests are recognized by the transceiver
through two possible channels:
• The bus lines for remote wake-up
• Pin WAKE for local wake-up.
In order to wake-up the transceiver remotely through the
bus lines, a filter mechanism is integrated. This
mechanism makes sure that noise and any present bus
failure conditions do not result into an erroneous wake-up.
Because of this mechanism it is not sufficient to simply pull
the CANH or CANL bus lines to a dominant level for a
certain time. To guarantee a successful remote wake-up
under all conditions, a message frame with a dominant
phase of at least the maximum specified t
it is required.

If VCCis provided the wake-up request can be read on the

activate the transceiver (switch to normal operating mode)
via pins STB and EN.
To prevent a false remote wake-up due to transients or
RF fields, the wake-up voltage levels have to be
maintained for a certain period of time. In the low power
modes the failure detection circuit remains partly active to
prevent an increased power consumption in the event of
failures 3, 3a, 4 and 7.

Protections
A current limiting circuit protects the transmitter output
stages against short-circuit to positive and negative
battery voltage.
If the junction temperature exceeds the typical value of
165 °C, the transmitter output stages are disabled.
Becausethetransmitteris responsible for the major part of
the power dissipation, this will result in a reduced power
dissipation and hence a lower chip temperature. All other
parts of the device will continue to operate.

SOLDERING
Introduction to soldering surface mount packages
Thistextgives 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
certainsurface mount ICs, but it is not suitableforfinepitch
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
totheprinted-circuitboardbyscreenprinting,stencillingor
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.
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.
• Forpackages with leads on four sides, the footprintmust
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.
Wave soldering
Conventional single wave soldering is not recommended
forsurface 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.

Suitability of surface mount IC packages for wave and reflow soldering methods
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
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.
