1. General description
The TJA1048 is a dual 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 the differential transmit and receive capability to (a
microcontroller with) a CAN protocol controller.
The TJA1048 belongs to the third generation of high- speed CAN transceivers from NXP
Semiconductors, offering significant improvements over first- and second-g eneration
devices such as the TJA1040. It offers improved Electro Magnetic Compatibility (EMC)
and ElectroStatic Discharge (ESD) performance, and also features:
Ideal passive behavior to the CAN bus when the supply voltage is off
A very low-current Standby mode with bus wake-up capability on both channels
TJA1048T can be interfaced directly to microcontrollers with supply voltages from
3Vto5V
These features make the TJA1048 an excellent choice for all types of HS-CAN networks
containing mor e than one HS-CAN interf ace that require a low-p ower mode with wake-up
capability via the CAN bus, especially for Body Control and Gateway units.

NXP Semiconductors TJA1048
Dual high-speed CAN transceiver with Standby mode
7. Functional description
The TJA1048 is a dual HS-CAN stand- alone transceiver with Standby mode and robust
ESD handling capability. It combines the functionality of two TJA1040/TJA1042
transceivers with improved EMC and quiescent curre nt performance. Improved slope
control and high DC handling capability on the bus pins provide additional application
flexibility.
7.1 Operating modes
The TJA1048 supports two operating modes per transceiver, Normal and Standb y. The
operating mode can be selected independently for each transceiver via pins STBN1 and
STBN2 (see Table 4).
7.1.1 Normal mode
A HIGH level on pin STBN1/STBN2 selects Normal mode. In this mode, the transceiver
can transmit and receive data via the bus lines CANH1/CANL1 and CANH2/CANL2 (see
Figure 1 for the block diagram). The differential receiver converts the analog data on the
bus lines into digital data which is output on pin RXD1/RXD2. The slope of the output
signals on the bus lines is controlled and optimized in a way that guarantees the lowest
possible EME.
7.1.2 Standby mode
A LOW level on pin STBN1/STBN2 selects Standby mode. In Standby mode, the
transceiver is not able to transmit or correctly receive data via the bus lines. The
transmitter and Normal-mod e receiver blocks are switched off to reduce supply current,
and only a low-powe r differential receiver monitors the bus lines for activity.
In Standby mode, the bus lines are biased to ground to minimize the system supply
current. The low-power receiver is supplied by VIO, and is capable of detecting CAN bus
activity even if VIO is the only supply voltage available. When pin RXD1/RXD2 goes LOW
to signal a wake-up request, a transition to Normal mode will not be triggered until
STBN1/STBN2 is forced HIGH.
A dedicated wake-up sequence (specified in ISO11898-5) must be received to wake-up
the TJA1048 from a low-power mode. This filtering is necessary to avoid spurious
wake-up even ts due to a dom ina n t clam pe d CAN bus or dominant phases caused by
noise or spikes on the bu s.
A valid 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)

Product data sheet Rev. 2 — 25 March 2011 6 of 21
NXP Semiconductors TJA1048
Dual high-speed CAN transceiver with Standby mode
The complete dominant-recessive -domin ant pattern must be received within tto(wake)bus to
be recognized as a valid wake-up pattern (see Figure 4). Pin RXD1/RXD2 will remain
recessive until the wake-up event has been triggered.
After a wake-up sequence has been detected, the TJA1048 will remain in Standby mode
with the bus signals reflected on RXD1/RXD2. Note that dominant or recessive phases
lasting less than tfltr(wake)bus will not be detected by the low-power differential receiver and
will not be reflected on RXD1/RXD2 in Standby mode.
A wake-up event will not be registered if any of the following events occurs while a
wake-up sequence is being transmitted:
The TJA1048 switches to Normal mode
The complete wake-up pattern was not received within tto(wake)bus
A VIO undervoltage is detected (VIO < Vuvd(VIO); see Section 7.2.3)
If any of these events occurs while a wake-up sequence is being received, the internal
wake-up logic will be reset and the complete wake-up sequence will have to be
re-transmitted to trigger a wake-up event.
7.2 Fail-safe features
7.2.1 TXD dominant time-out function
A 'TXD dominant time-out' timer is started when pin TXD1/TXD2 is set LOW. If the LOW
state on this pin persists for longer than tto(dom)TXD, the transmitter is disabled, releasing
the bus lines to recessive state. This function pre vents a hardware and/or software
application failure from driving the bus lines to a permanent dominant state (blocking all
network communications). The TXD dominant time-out timer is reset when pin
TXD1/TXD2 is set HIGH. The TXD dominant time-out time also defines the minimum
possible bit rate of 40 kbit/s. The TJA104 8 has two TXD dominant time-out timers that
operate independently of each other.

NXP Semiconductors TJA1048
Dual high-speed CAN transceiver with Standby mode
7.2.2 Internal biasing of TXD1, TXD2, STBN1 and STBN2 input pins
Pins TXD1 and TXD2 have internal pull-ups to VIO and pins STBN1 and STBN2 have
internal pull-downs to GNDA and GNDB. This ensures a safe, d efined state if any of these
pins is left floating. Pins GNDA and GNDB must be connected together in the application.
Pull-up/pull-down current s flow in these pins in all states. Pins TXD1 and TXD2 should be
held HIGH in Standby mode to minimize standby currents; pins STBN1 an d STBN2
should be held LOW.
7.2.3 Undervoltage detection on pins VCC and VIO
Should VCC drop below the VCC undervolt age detection le vel, Vuvd(VCC), both transceiver s
will switch to Standby mode. The logic state of pins STBN1 and STBN2 will be ignored
until VCC has recovered.
Should VIO drop below the VIO under volt age detection level, V uvd(VIO), the transceivers will
switch off and disengage from the bus (zero load) until VIO has recovered.
7.2.4 Overtemperature protection
The output dri vers are protecte d against over temperature cond itions. If the virtual ju nction
temperature exceed s the shut down junction temperature , Tj(sd), both output drivers will be
disabled. When the virtual junction temperature drops below Tj(sd) again, the output
drivers will recover independently once TXD1/TXD2 has been reset to HIGH. Including
the TXD1/TXD2 condition prevents output driver oscillation due to small variations in
temperature.
7.3 VIO supply pin
Pin VIO should be connecte d to the microcontrolle r supply volta ge (see Figure 5). This will
adjust the signal levels of pins TXD1, TXD2, RXD1, RXD2, STBN1 and STBN2 to the I/O
levels of the microcontroller. Pin VIO also provides the internal supply voltage for the
transceiver’s low-power differential receiver. For applications running in low-power mode,
this allows the bus lines to be monito re d fo r act ivity ev en if ther e is no supp ly vo ltage on
pin VCC.

15. Handling information
All input and output pins are protected against ElectroStatic Discharge (ESD) under
normal handling. When handling ensure that the appropriate prec a u tio ns ar e 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 of ten preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on on e 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
W ave soldering is a joining te chnology in which the joints are m ade 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 solde r lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads ha ving 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 ve rsus SnPb soldering
16.3 Wave soldering
Key characteristics in wave soldering are:

NXP Semiconductors TJA1048
Dual high-speed CAN transceiver with Standby mode
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 ve rsus SnPb soldering; note th at a lead-free reflow process usua lly 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 th e 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) an d cooling down. It is imperative that the peak
temperature is high enoug h for the solder to make reliable solder joint s (a solder paste
characteristic). In addition, the peak temperature must be low en ough that the
packages and/or boards are not damaged. Th e peak temperature of the package
depends on p ackage thickness and volume and is classified in accordance with
Table 9 and 10
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 10.
