TJA1048
Dual high-speed CAN transceiver with Standby mode
Rev. 4 — 15 January 2015
Product data sheet
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 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-generation
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
• Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V
The TJA1048 implements the CAN physical layer as defined in the current ISO11898
standard (ISO11898-2:2003, ISO11898-5:2007). Pending the release of the updated
version of ISO11898-2 including CAN FD, additional timing parameters defining loop
delay symmetry are specified. This implementation enables reliable communication in the
CAN FD fast phase at data rates up to 2 Mbit/s.
These features make the TJA1048 an excellent choice for all types of HS-CAN networks
containing more than one HS-CAN interface that require a low-power mode with wake-up
capability via the CAN bus, especially for Body Control and Gateway units.

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 TJA1042/3 transceivers with
improved EMC and quiescent current 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 Standby. The
operating mode can be selected independently for each transceiver via pins STBN1 and
STBN2 (see Table 4).

wake-up request detected
no wake-up request detected
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 slopes of the output
signals on the bus lines are controlled internally and are 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-mode receiver blocks are switched off to reduce supply current,
and only a low-power 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 events due to a dominant clamped CAN bus or dominant phases caused by
noise or spikes on the bus.
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)

NXP Semiconductors
Dual high-speed CAN transceiver with Standby mode
The complete dominant-recessive-dominant 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.

Wake-up timing
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 prevents 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 TJA1048 has two TXD dominant time-out timers that
operate independently of each other.

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, defined state if any of these
pins is left floating. Pins GNDA and GNDB must be connected together in the application.
Pull-up/pull-down currents flow in these pins in all states. Pins TXD1 and TXD2 should be
held HIGH in Standby mode to minimize the supply current; pins STBN1 and STBN2
should be held LOW.
7.2.3 Undervoltage detection on pins VCC and VIO
Should VCC drop below the VCC undervoltage detection level, Vuvd(VCC), both transceivers
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 undervoltage detection level, Vuvd(VIO), the transceivers will
switch off and disengage from the bus (zero load) until VIO has recovered.
7.2.4 Overtemperature protection
The output drivers are protected against overtemperature conditions. If the virtual junction
temperature exceeds the shutdown 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 connected to the microcontroller supply voltage (see Figure 7). 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 monitored for activity even if there is no supply voltage 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 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 11) 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 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 11.
