Product data sheet
1. General description
The TJA1021 is the interface between the Local Interconnect Network (LIN) master/slave
protocol controller and the physical bus in a LIN. It is primarily intended for in-vehicle
sub-networks using baud rates from 1 kBd up to 20 kBd and is LIN 2.1/SAE J2602
compliant. The TJA1021 is pin-to-pin compatible with the TJA1020 with an improved
ElectroStatic Discharge (ESD) specification.
The transmit data stream of the protocol controller at the transmit data input (TXD) is
converted by the TJA1021 into a bus signal with optimized slew rate and wave shaping to
minimize ElectroMagnetic Emission (EME). The LIN bus output pin is pulled HIGH via an
internal termination resistor. For a master application, an external resistor in series with a
diode should be connected between pin INH or pin VBAT and pin LIN. The receiver detects
the data stream at the LIN bus input pin and transfers it via pin RXD to the microcontroller.
In Sleep mode, the power consumption of the TJA1021 is very low. In failure modes, the
power consumption is reduced to a minimum.

All parameters are guaranteed by design over the virtual junction temperature range. Products are 100 % tested at 125 °C ambient
temperature on wafer level (pre-testing). Cased products are 100 % tested at 25 °C ambient temperature (final testing). Both pre-testing
and final testing use correlated test conditions to cover the specified temperature and power supply voltage range.

Junction temperature in accordance with IEC 60747-1. An alternative definition is: Tvj = Tamb + P × Rth(vj-a), where Rth(vj-a) is a fixed
value. The rating for Tvj limits the allowable combinations of power dissipation (P) and ambient temperature (Tamb).

7. Functional description
The TJA1021 is the interface between the LIN master/slave protocol controller and the
physical bus in a Local Interconnect Network (LIN). The TJA1021 is LIN 2.1/SAE J2602
compliant and provides optimum ElectroMagnetic Compatibility (EMC) performance due
to wave shaping of the LIN output.
The /20 versions of the TJA1021 are optimized for the maximum specified LIN
transmission speed of 20 kBd; the /10 version of the TJA1021 is optimized for the LIN
transmission speed of 10.4 kBd as specified by the SAE J2602.
7.1 Operating modes
The TJA1021 supports modes for normal operation (Normal mode), power-up (Power-on
mode) and very-low-power operation (Sleep mode). An intermediate wake-up mode
between Sleep and Normal modes is also supported (Standby mode). Figure 3 shows the
state diagram.

LIN 2.1/SAE J2602 transceiver

Power-on mode is entered after switching on VBAT.
7.2 Sleep mode
This mode is the most power-saving mode of the TJA1021. Despite its extreme low
current consumption, the TJA1021 can still be woken up remotely via pin LIN, or woken up
locally via pin WAKE_N, or activated directly via pin SLP_N. Filters at the inputs of the
receiver (LIN), of pin WAKE_N and of pin SLP_N prevent unwanted wake-up events due
to automotive transients or EMI. All wake-up events have to be maintained for a certain
time period (twake(dom)LIN, twake(dom)WAKE_N and tgotonorm).
Sleep mode is initiated by a falling edge on pin SLP_N in Normal mode. To enter Sleep
mode successfully (INH becomes floating), the sleep command (pin SLP_N = LOW) must
be maintained for at least tgotosleep.
In Sleep mode the internal slave termination between pins LIN and VBAT is disabled to
minimize the power dissipation in the event that pin LIN is short-circuited to ground. Only a
weak pull-up between pins LIN and VBAT is present.
Sleep mode can be activated independently from the actual level on pin LIN, pin TXD or
pin WAKE_N. So it is guaranteed that the lowest power consumption is achievable even in
case of a continuous dominant level on pin LIN or a continuous LOW on pin WAKE_N.
When VBAT drops below the power-on-reset threshold Vth(POR)L, the TJA1021 enters
Sleep mode.
7.3 Standby mode
Standby mode is entered automatically whenever a local or remote wake-up occurs while
the TJA1021 is in Sleep mode. These wake-up events activate pin INH and enable the
slave termination resistor at the pin LIN. As a result of the HIGH condition on pin INH the
voltage regulator and the microcontroller can be activated.
Standby mode is signalled by a LOW-level on pin RXD which can be used as an interrupt
for the microcontroller.
In Standby mode (pin SLP_N is still LOW), the condition of pin TXD (weak pull-down or
strong pull-down) indicates the wake-up source: weak pull-down for a remote wake-up
request and strong pull-down for a local wake-up request.
Setting pin SLP_N HIGH during Standby mode results in the following events:
• An immediate reset of the wake-up source flag; thus releasing the possible strong
pull-down at pin TXD before the actual mode change (after tgotonorm) is performed
• A change into Normal mode if the HIGH level on pin SLP_N has been maintained for
a certain time period (tgotonorm)
• An immediate reset of the wake-up request signal on pin RXD
7.4 Normal mode
In Normal mode the TJA1021 is able to transmit and receive data via the LIN bus line. The
receiver detects the data stream at the LIN bus input pin and transfers it via pin RXD to the
microcontroller (see Figure 1): HIGH at a recessive level and LOW at a dominant level on
the bus. The receiver has a supply-voltage related threshold with hysteresis and an

NXP Semiconductors
LIN 2.1/SAE J2602 transceiver
integrated filter to suppress bus line noise. The transmit data stream of the protocol
controller at the TXD input is converted by the transmitter into a bus signal with optimized
slew rate and wave shaping to minimize EME. The LIN bus output pin is pulled HIGH via
an internal slave termination resistor. For a master application an external resistor in
series with a diode should be connected between pin INH or VBAT on one side and pin LIN
on the other side (see Figure 6).
When in Sleep, Standby or Power-up mode, the TJA1021 enters Normal mode whenever
a HIGH level on pin SLP_N is maintained for a time of at least tgotonorm.
The TJA1021 switches to Sleep mode in case of a LOW-level on pin SLP_N, maintained
for a time of at least tgotosleep.
7.5 Wake-up
When VBAT exceeds the power-on-reset threshold voltage Vth(POR)H, the TJA1021 enters
Power-on mode. Though the TJA1021 is powered-up and INH is HIGH, both the
transmitter and receiver are still inactive. If SLP_N = 1 for t > tgotonorm, the TJA1021 enters
Normal mode.
There are three ways to wake-up a TJA1021 which is in Sleep mode:
1. Remote wake-up via a dominant bus state of at least twake(dom)LIN
2. Local wake-up via a negative edge at pin WAKE_N
3. Mode change (pin SLP_N is HIGH) from Sleep mode to Normal mode
7.6 Remote and local wake-up
A falling edge at pin LIN followed by a LOW level maintained for a certain time period
(twake(dom)LIN) and a rising edge at pin LIN respectively (see Figure 4) results in a remote
wake-up. It should be noted that the time period twake(dom)LIN is measured either in Normal
mode while TXD is HIGH, or in Sleep mode irrespective of the status of pin TXD.
A falling edge at pin WAKE_N followed by a LOW level maintained for a certain time
period (twake(dom)WAKE_N) results in a local wake-up. The pin WAKE_N provides an internal
pull-up towards pin VBAT. In order to prevent EMI issues, it is recommended to connect an
unused pin WAKE_N to pin VBAT.
After a local or remote wake-up, pin INH is activated (it goes HIGH) and the internal slave
termination resistor is switched on. The wake-up request is indicated by a LOW active
wake-up request signal on pin RXD to interrupt the microcontroller.
7.7 Wake-up via mode transition
It is also possible to set pin INH HIGH with a mode transition towards Normal mode via pin
SLP_N. This is useful for applications with a continuously powered microcontroller.
7.8 Wake-up source recognition
The TJA1021 can distinguish between a local wake-up request on pin WAKE_N and a
remote wake-up request via a dominant bus state. 'A local wake-up request sets the
wake-up source flag. The wake-up source can be read on pin TXD in the Standby mode. If

has been added, a HIGH level indicates a remote wake-up request (weak pull-down at pin
TXD) and a LOW level indicates a local wake-up request (strong pull-down at pin TXD;
much stronger than the external pull-up resistor).
The wake-up request flag (signalled on pin RXD) as well as the wake-up source flag
(signalled on pin TXD) are reset immediately after the microcontroller sets pin SLP_N
HIGH.
7.9 TXD dominant time-out function
A TXD dominant time-out timer circuit prevents the bus line from being driven to a
permanent dominant state (blocking all network communication) if pin TXD is forced
permanently LOW by a hardware and/or software application failure. The timer is triggered
by a negative edge on pin TXD. If the duration of the LOW-level on pin TXD exceeds the
internal timer value (tto(dom)TXD), the transmitter is disabled, driving the bus line into a
recessive state. The timer is reset by a positive edge on pin TXD.
7.10 Fail-safe features
Pin TXD provides a pull-down to GND in order to force a predefined level on input pin TXD
in case the pin TXD is unsupplied.
Pin SLP_N provides a pull-down to GND in order to force the transceiver into Sleep mode
in case the pin SLP_N is unsupplied.
Pin RXD is set floating in case of lost power supply on pin VBAT.
The current of the transmitter output stage is limited in order to protect the transmitter
against short circuit to pins VBAT or GND.
A loss of power (pins VBAT and GND) has no impact on the bus line and the
microcontroller. There are no reverse currents from the bus. The LIN transceiver can be
disconnected from the power supply without influencing the LIN bus.
The output driver at pin LIN is protected against overtemperature conditions. If the
junction temperature exceeds the shutdown junction temperature Tj(sd), the thermal
protection circuit disables the output driver. The driver is enabled again when the junction
temperature has dropped below Tj(sd) and a recessive level is present at pin TXD.
If VBAT drops below Vth(VBATL)L, a protection circuit disables the output driver. The driver is
enabled again when VBAT > Vth(VBATL)H and a recessive level is present at pin TXD.

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 10) 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 10.
