TJA1021  
LIN 2.0/SAE J2602 transceiver  
Rev. 01 — 16 October 2006  
Objective 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 2.0/SAE J2602  
compliant. The TJA1021 is pin-to-pin compatible with the TJA1020 and improved on  
ElectroStatic Discharge (ESD).  
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, whereas in failure  
modes the power consumption is reduced to a minimum.

NXP Semiconductors  
LIN 2.0/SAE J2602 transceiver  
[1] The standby mode is entered automatically upon any local or remote wake-up event during sleep mode. Pin INH and the 30 kΩ  
termination resistor at pin LIN are switched on.  
[2] The internal wake-up source flag (set if a local wake-up did occur and fed to pin TXD) will be reset when entering normal mode (SLP_N  
goes HIGH).  
[3] The wake-up interrupt (on pin RXD) is released when entering normal mode (SLP_N goes HIGH).  
[4] The normal mode is entered during a positive edge on SLP_N. As long as TXD is LOW, the transmitter is off. In the event of a  
short-circuit to ground on pin TXD, the transmitter will be disabled.  
[5] The 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 waken up remotely via pin LIN, or waken 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 are preventing unwanted wake-up  
events due to automotive transients or EMI. All wake-up events have to be maintained for  
a certain time period (tdom(LIN), twake(dom)WAKE_N and tgotonorm).  
The sleep mode is initiated by a falling edge on the pin SLP_N in normal mode. To enter  
the 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 case pin LIN is short-circuited to ground. Only a weak  
pull-up between pins LIN and VBAT is present.  
The 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  
The standby mode is entered automatically whenever a local or remote wake-up occurs  
while the TJA1021 is in its 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.  
The standby mode is signalled by a LOW-level on pin RXD which can be used as an  
interrupt for the microcontroller.  
In the 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) while pin TXD is pulled HIGH  
An immediate reset of the wake-up request signal on pin RXD

7.4 Normal mode  
In the 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 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 7).  
Being in the 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  
the 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  
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 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  
.
A falling edge at pin LIN followed by a LOW-level maintained for a certain time period  
(tdom(LIN)) and a rising edge at pin LIN respectively (see Figure 5) results in a remote  
wake-up. It should be noted that the time period tdom(LIN) is measured either in normal  
mode while TXD is HIGH, or in sleep mode irrespective of the status of pin TXD.  
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. The wake-up source flag is set in case  
the wake-up request was a local one. The wake-up source can be read on pin TXD in the  
standby mode. If an external pull-up resistor on pin TXD to the power supply voltage of the  
microcontroller 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 on TXD = 0, after  
the junction temperature 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 on TXD = 0, after VBAT > Vth(VBATL)H and a recessive level is present at pin  
TXD.

15. Handling information  
Inputs and outputs are protected against electrostatic discharge in normal handling.  
However, to be completely safe you must take normal precautions appropriate to handling  
integrated circuits.  
16. Soldering  
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 PbSn soldering  
16.3 Wave soldering

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 PbSn 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 10 and 11

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.
