TJF1051
High-speed CAN transceiver
Rev. 4 — 15 January 2015
Product data sheet
1. General description
The TJF1051 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 CAN industrial applications, providing
differential transmit and receive capability to (a microcontroller with) a CAN protocol
controller.
The TJF1051 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 TJA1050. It offers improved ElectroMagnetic Compatibility (EMC)
and ElectroStatic Discharge (ESD) performance, and also features ideal passive behavior
to the CAN bus when the supply voltage is off. The TJF1051T/3 can be interfaced directly
to microcontrollers with supply voltages from 3 V to 5 V.
The TJF1051 implements the CAN physical layer as defined in the current ISO11898
standard (ISO11898-2:2003). 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 TJF1051 an excellent choice for all types of HS-CAN networks,
in nodes that do not require a standby mode with wake-up capability via the bus.

7. Functional description
The TJF1051 is a stand-alone high-speed CAN transceiver with Silent mode. It combines
the functionality of the TJA1050 transceiver with improved EMC and ESD handling
capability. Improved slope control and high DC handling capability on the bus pins
provides additional application flexibility. The TJF1051T/3 allows for direct interfacing to
microcontrollers with supply voltages down to 3 V.
7.1 Operating modes
The TJF1051 supports two operating modes, Normal and Silent. The operating mode is
selected via pin S. See Table 4 for a description of the operating modes under normal
supply conditions.

7.1.1 Normal mode
A LOW level on pin S selects Normal mode. In this mode, the transceiver is able to
transmit and receive data via 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
levels.
7.1.2 Silent mode
A HIGH level on pin S selects Silent mode. In Silent mode the transmitter is disabled,
releasing the bus pins to recessive state. All other IC functions, including the receiver,
continue to operate as in Normal mode. Silent mode can be used to prevent a faulty CAN
controller from disrupting all network communications.
7.2 Fail-safe features
7.2.1 TXD dominant time-out function
A ‘TXD dominant time-out’ timer is started when pin TXD is set LOW. If the LOW state on
pin TXD 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 TXD is set HIGH.
The TXD dominant time-out time also defines the minimum possible bit rate of 40 kbit/s.

7.2.2 Internal biasing of TXD and S input pins
Pin TXD has an internal pull-up to VIO and pin S has an internal pull-down to GND. This
ensures a safe, defined state in case one (or both) of these pins is left floating.
7.2.3 Undervoltage detection on pins VCC and VIO
Should VCC or VIO drop below their respective undervoltage detection levels (Vuvd(VCC)
and Vuvd (VIO); see Table 7), the transceiver will switch off and disengage from the bus
(zero load) until VCC and VIO have 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), the output drivers will be
disabled until the virtual junction temperature falls below Tj(sd) and TXD becomes
recessive again. Including the TXD condition ensures that output driver oscillations due to
temperature drift are avoided.
7.3 VIO supply pin (TJF1051T/3)
Pin VIO on the TJF1051T/3 should be connected to the microcontroller supply voltage
(see Figure 6). This adjusts the signal levels on pins TXD, RXD and S to the I/O levels of
the microcontroller. In the TJF1051T, the VIO input is internally connected to VCC. This
sets the signal levels of pins TXD, RXD and S to levels compatible with 5 V
microcontrollers.

fixed value to be used for the calculation of Tvj. The rating for Tvj limits the allowable combinations of power dissipation (P) and ambient
temperature (Tamb).

14. 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.
15. 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”.
15.1 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.
15.2 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

• 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
15.4 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 8) 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 8.
