TJA1027 LIN 2.2A/SAE J2602 transceiver Rev. 2 — 24 April 2013 Product data sheet 1. General description The TJA1027 is the interface between the Local Interconnect Network (LIN) master/slave protocol controller and the physical bus in a LIN network. It is primarily intended for in-vehicle sub-networks using baud rates up to 20 kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and SAE J2602. The TJA1027 is pin-compatible with the TJA1020 and the TJA1021. The transmit data stream generated by the protocol controller is converted by the TJA1027 into an optimized bus signal shaped to minimize ElectroMagnetic Emissions (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 VBAT and pin LIN. The receiver detects a receive data stream on the LIN bus input pin and transfers it via pin RXD to the microcontroller. Power consumption is very low in Sleep mode. However, the TJA1027 can still be woken up via pins LIN and SLP_N. 2.

Functional description The TJA1027 is the interface between the LIN master/slave protocol controller and the physical bus in a LIN network. According to the Open System Interconnect (OSI) model, this is the LIN physical layer. The LIN transceiver is optimized for, but not limited to, automotive applications with excellent ElectroMagnetic Compatibility (EMC) performance. 7.1 LIN 2.x/SAE J2602 compliant The TJA1027 is fully LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and SAE J2602 compliant. The LIN physical layer is independent of higher OSI model layers (e.g. the LIN protocol). Consequently, nodes containing a LIN 2.2A-compliant physical layer can be combined, without restriction, with LIN physical layer nodes that comply with earlier revisions (LIN 1.0, LIN 1.1, LIN 1.2, LIN 1.3, LIN 2.0, LIN 2.1 and LIN 2.2). 7.2 Operating modes The TJA1027 supports modes for normal operation (Normal mode) and very-low-power operation (Sleep mode). An intermediate wake-up mode between Sleep and Normal modes is also supported (Standby mode). The state diagram is shown in Figure 3.

[4] A positive edge on SLP_N will trigger a transition to Normal mode The transmitter will be off if TXD is LOW and will be enabled as soon as TXD goes HIGH.

All rights reserved. 6 of 24 TJA1027 NXP Semiconductors LIN 2.2A/SAE J2602 transceiver 7.2.1 Reset mode When the TJA1027 is in Reset mode, it ignores all input signals and all output drivers are off. The TJA1027 switches to Reset mode when the voltage on VBAT drops below the LOW-level power-on reset threshold, Vth(POR)L. When the voltage on VBAT rises above the HIGH-level power-on reset threshold, Vth(POR)H, the TJA1027 switches to Sleep mode. 7.2.2 Sleep mode The TJA1027 consumes significantly less power in Sleep mode than in any other mode. Even though current consumption is extremely low in Sleep mode, the TJA1027 can still be woken up remotely via pin LIN or activated directly via pin SLP_N. Filters on the receiver input (LIN) and on pin SLP_N prevent unwanted wake-up events occurring due to automotive transients or radio frequency interference. All wake-up events must be maintained for a specific period of time (twake(dom)LIN or tgotonorm). Sleep mode is initiated by a falling edge on pin SLP_N in Normal mode. The LIN transmit path is immediately disabled when pin SLP_N goes LOW. In order to ensure the TJA1027 switches successfully to Sleep mode, the sleep command (pin SLP_N = LOW) must be maintained for at least tgotosleep. Sleep mode activation is independent of the levels on pins LIN or TXD. So the lowest possible power consumption can be guaranteed, even when there is a continuous dominant level on pins LIN and TXD. 7.2.3 Standby mode Standby mode is activated automatically when a local or remote wake-up event occurs while the TJA1027 is in Sleep mode. In Standby mode, pin RXD is held LOW to provide an interrupt flag for the microcontroller. 7.2.4 Normal mode In Normal mode, the TJA1027 can transmit and receive data via the LIN bus. The receiver detects the data stream on the LIN bus input pin and transfers it via pin RXD to the microcontroller (see Figure 6): HIGH for a recessive level and LOW for 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 from the protocol controller is detected on pin TXD and is converted by the transmitter into an optimized bus signal shaped 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 VBAT and pin LIN (see Figure 6). If pin SLP_N is pulled HIGH while the TJA1027 is in Sleep or Standby mode, the LIN transceiver switches to Normal mode after tgotonorm.

All rights reserved. 7 of 24 TJA1027 NXP Semiconductors LIN 2.2A/SAE J2602 transceiver 7.3 Transceiver wake-up 7.3.1 Remote wake-up via the LIN bus A falling edge on pin LIN followed by a LOW level maintained for twake(dom)LIN followed by a rising edge on pin LIN triggers a remote wake-up (see Figure 4). 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. LIN recessive VBUSrec VBUSdom VLIN twake(dom)LIN LIN dominant ground sleep mode standby mode 015aaa241 Fig 4. Remote wake-up behavior 7.3.2 Wake-up via pin SLP_N If SLP_N is held HIGH for tgotonorm, the TJA1027 will switch from Sleep mode to Normal mode. 7.4 Operation during automotive cranking pulses TJA1027 remains fully operational during automotive cranking pulses because the LIN transceiver is fully specified down to VBAT = 5 V. 7.5 Operation when supply voltage is outside specified operating range If VBAT > 18 V or VBAT < 5 V, the TJA1027 may remain operational, but parameter values cannot be guaranteed to remain within the operation ranges specified in Table 7 and Table 8. In Normal mode: • If the input level on pin TXD is HIGH, the LIN transmitter output on pin LIN will be recessive. • If the input level on pin LIN is recessive, the receiver output on pin RXD will be HIGH. • If the voltage on pin VBAT rises to 27 V (e.g. during an automotive jump start), the total LIN network pull-up resistance should be greater than 680 and the total LIN network capacitance should be less than 6.8 nF to ensure reliable LIN data transfer. • If the voltage on pin VBAT drops below the LOW-level VBAT LOW threshold, Vth(VBATL)L, the LIN transmit path is interrupted and the LIN output remains recessive. The LIN transmit path is switched on again when VBAT rises above Vth(VBATL)H and the input to pin TXD is recessive.

All rights reserved. 8 of 24 TJA1027 NXP Semiconductors LIN 2.2A/SAE J2602 transceiver If the voltage on pin VBAT drops below the LOW-level power-on reset threshold, Vth(POR)L, the TJA1027 switches to Reset mode (i.e. all output drivers are disabled and all inputs are ignored). The TJA1027 switches to Sleep mode if VBAT > Vth(POR)H. 7.6 Fail-safe features Pin TXD provides a pull-down to GND in order to force a predefined level on the transmit data input if the pin is disconnected. Pin SLP_N provides a pull-down to GND in order to force the transceiver into Sleep mode if pin SLP_N is disconnected. Pin RXD is set floating if VBAT is disconnected. The current in the transmitter output stage is limited in order to protect the transmitter against short circuits to pins VBAT or GND. A loss of power (pins VBAT and GND) has no impact on the bus line or on the microcontroller. No reverse currents flow from the bus into pin LIN. The current path from VBAT to LIN via the integrated LIN slave termination resistor remains. The LIN transceiver can be disconnected from the power supply without influencing the LIN bus. The output driver on 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 falls below Tj(sd) and pin TXD is recessive. The initial TXD dominant check prevents the bus line from being driven to a permanent dominant state (blocking all network communications) if pin TXD is forced permanently LOW by a hardware and/or software application failure. The TXD input level is checked after a transition to Normal mode. If TXD is LOW, the transmit path will remain disabled and will only be enabled when TXD goes HIGH.

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: TJA1027 Product data sheet All information provided in this document is subject to legal disclaimers.

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 Table 10. SnPb eutectic process (from J-STD-020D) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 < 2.5 235 220 2.5 220 220 Table 11.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 9.
