TJA1083 FlexRay node transceiver Rev. 1 — 10 October 2012 Product data sheet 1. General description The TJA1083 FlexRay node transceiver is compliant with the FlexRay Electrical Physical Layer specification V3.0.1 (see Ref. 1). In order to meet JASPAR the equirements, it implements the ‘Increased voltage amplitude transmitter’ functional class. It is primarily intended for communication systems operating at between 2.5 Mbit/s and 10 Mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a FlexRay network. The TJA1083 offers an optimized solution for Electronic Control Unit (ECU) applications that do not need enhanced power management and are typically switched by the ignition or activated by a dedicated wake-up line. The TJA1083 provides a differential transmit capability to the network and a differential receive capability to the FlexRay controller. It offers excellent ElectroMagnetic Compatibility (EMC) performance as well as high ElectroStatic Discharge (ESD) protection. The TJA1083 actively monitors system performance using dedicated error and status information (readable by any microcontroller), as well as internal voltage and temperature monitoring. 2.

All rights reserved. 6 of 41 TJA1083 NXP Semiconductors FlexRay node transceiver 6.1.1.1 Bus activity and idle detection In Normal mode, bus activity and bus idle are detected as follows: • Bus activity is detected when the absolute differential voltage on the bus lines is higher than Vi(dif)det(act) for tdet(act)(bus): – If the differential voltage on the bus lines is lower than VIL(dif) after bus activity has been detected, pin RXD switches LOW. – If the differential voltage on the bus lines is higher than VIH(dif) after bus activity has been detected, pin RXD remains HIGH. • Bus idle is detected when the absolute differential voltage on the bus lines is lower than Vi(dif)det(act) for tdet(idle)(bus). This results in pin RXD being switched HIGH or staying HIGH. 6.1.2 Standby mode Standby mode is a low-power mode featuring very low current consumption. In Standby mode, the transceiver is unable to transmit or receive data since both the transmitter and the normal receiver are switched off. The low-power receiver is activated to monitor the bus for wake-up activity, provided an undervoltage has not been detected on pin VCC. The low-power receiver is deactivated if an undervoltage is detected on pin VCC - with the result that the wake flag is not set if a wake-up pattern or dedicated data frame is received. Pins ERRN and RXD indicate the status of the wake flag when VIO and VCC are within their operating ranges. See Table 3 for a description of pins ERRN and RXD when an undervoltage is detected on pin VIO or pin VCC. The status register cannot be read via the SPI interface if an undervoltage is detected on pin VIO. The BGE input has no effect in Standby mode. 6.1.3 Power-off mode The transmitter and the two receivers (normal and low-power) are deactivated in Power-off mode. As a result, the wake flag is not set if a wake-up pattern or dedicated data frame is received. If the voltage at VCC rises above Vth(rec)POR, the transceiver switches to Standby mode and the digital section is reset. If VCC subsequently drops below Vth(det)POR, the transceiver reverts to Power-off mode (see Section 6.2). The status register cannot be read via the SPI interface in Power-off mode. 6.1.4 State transitions Figure 4 shows the TJA1083 state transition diagram. The timing diagram for the ERRN indication signal during transitions between Normal and Standby modes, when the error flag is set and the wake flag is not set, is illustrated in Figure 5 and described in Table 6.

The ramp up of the different power supplies can vary, depending on the state or value of a number of signals and parameters. The power-up behavior of the TJA1083 is not affected by the sequence in which power is supplied to these pins or by the voltage ramp up. As an example, Figure 6 shows one possible power supply ramp-up scenario. The digital section of the TJA1083 is supplied by VCC. The voltage on pin VCC ramps up before the voltage on pin VIO. As long as the voltage on VCC remains below the power-on reset recovery threshold, Vth(rec)POR, the internal state machine is inactive and the transceiver is totally passive, remaining in Power-off mode. As soon as the voltage rises above the Vth(rec)POR threshold, the internal state machine starts running, setting the PWON flag and switching the TJA1083 to Standby mode. This initializes the VCC and VIO under-voltage flags to the set state (since both VCC and VIO are actually in undervoltage state just after power-on). Once both VIO and VCC have reached their operating ranges, the under-voltage flags are reset. The operating mode is then determined by the level on STBN (the TJA1083 switches to Normal mode if STBN is HIGH and remains in Standby mode if STBN is LOW), provided VIO and VCC are above their respective undervoltage recovery levels (Vuvr(VIO) and Vuvr(VCC)).

A wake-up pattern consists of at least two consecutive wake-up symbols. A wake-up symbol comprises a DATA_0 phase lasting longer than tdet(wake)DATA_0 followed by an idle phase lasting longer than tdet(wake)idle, provided both wake-up symbols occur within a time span of tdet(wake)tot (see Figure 8). The transceiver also wakes up if DATA_1 phases are substituted for the idle phases. wake-up < tdet(wake)tot Vdif (mV) > tdet(wake)idle > tdet(wake)idle 0 -500 > tdet(wake)DATA_0 > tdet(wake)DATA_0 > tdet(wake)idle > tdet(wake)idle +500 0 -500 > tdet(wake)DATA_0 > tdet(wake)DATA_0 wake-up symbol wake-up symbol wake-up pattern 015aaa007 Fig 8. Bus wake-up timing See Ref. 1 for more details of the wake-up mechanism. 6.3.2 Bus wake-up via dedicated FlexRay data frame The TJA1083 wake flag is set when a dedicated data frame emulating a valid wake-up pattern, as shown in Figure 9, is received. The DATA_0 and DATA_1 phases of the emulated wake-up symbol are interrupted by the Byte Start Sequence (BSS) preceding each byte in the data frame. With a data rate of 10 Mbit/s, the interruption has a maximum duration of 130 ns and does not prevent the transceiver from recognizing the wake-up pattern in the payload. For longer interruptions at lower data rates (5 Mbit/s and 2.5 Mbit/s), the wake-up pattern should be used (see Section 6.3.1). The wake flag is not set if an invalid wake-up pattern is received. See Ref. 1 for more details on invalid wake-up patterns. TJA1083 Product data sheet All information provided in this document is subject to legal disclaimers.

Minimum bus pattern for bus wake-up via dedicated FlexRay data frame 6.4 Bus error detection The TJA1083 detects the following bus errors during transmission: • • • • • Short-circuit BP to BM at the ECU connector or on the bus Short-circuit BP to GND at the ECU connector or on the bus Short-circuit BM to GND at the ECU connector or on the bus Short-circuit BP to VCC at the ECU connector or on the bus Short-circuit BM to VCC at the ECU connector or on the bus The bus error flag is not set when a wake-up pattern or a FlexRay Collision Avoidance Symbol (CAS) is being transmitted or received. 6.5 Fail silent behavior Three mechanisms guarantee the ‘fail silent’ behavior of the TJA1083: • The TXEN clamped flag is set if pin TXEN goes LOW for longer than tdetCL(TXEN) in Normal mode; the transmitter is disabled. • The BGE clamped flag is set if pin BGE goes HIGH for longer than tdetCL(BGE) in Normal mode; no action is taken. • If a loss-of-ground occurs at the transceiver, resulting in the TJA1083 switching to Power-off mode, no current flows out of the digital input pins (TXD, TXEN, BGE, STBN, SCLK, SCSN); see Table 3 for details of the behavior of the bus pins. 6.6 TJA1083 flags The TJA1083 has 11 status/error flags.

All flags can be individually read out on pin SDO via a 16-bit SPI interface when the transceiver is configured in SPI mode. The status register bits are described in Table 8.

To switch to simple error indication mode, SCSN must be held LOW (connected to GND) and SCLK held HIGH (connected to VIO) for longer than tdet(L)(SCLK) (provided a VIO undervoltage has not occurred). When the TJA1083 is in simple error indication mode, a rising edge on SCSN initiates a transition to SPI mode (again provided a VIO undervoltage has not occurred); see Figure 10.

This means that the status bit is reset once the status register has been completely read (provided the corresponding error flag has been reset). If an error condition is detected in Normal mode, pin ERRN goes LOW (provided one of the error bits, S5 to S10, is set). Pin ERRN goes HIGH again once all the error bits have been reset. 6.8.2 Simple error indication mode If an error condition is detected in Normal mode, pin ERRN goes LOW once the relevant error flag has been set. Pin ERRN stays stable for at least tERRNL(min) and goes HIGH again when all error conditions have been cleared and all flags have been reset. Error flags are not latched. It is not possible to read-out the status bits in this mode. 6.9 SPI interface The TJA1083 includes a 16-bit SPI interface to enable a host to read the status register when the transceiver is in SPI mode (see Section 6.8). While pin SCSN is HIGH, the SDO output is in a high-impedance state. To begin a status register readout, the host must force pin SCSN LOW. This action causes the SDO pin to output a LOW level by default. The data on pin SDO is then shifted out on the rising edge of the clock signal on pin SCLK. The status bits shifted out on pin SDO are active HIGH. The status bits are refreshed and pin SDO returned to a high-impedance state once the status register has been read successfully (after exactly 16 clock cycles) and SCSN has been forced HIGH again. Clock signals on SCLK are ignored while SCSN is HIGH. The timing diagram for the SPI readout is illustrated in Figure 11. The SLCK period ranges from 500 ns to 100 s (10 kbit/s to 2 Mbit/s).

All rights reserved. 15 of 41 TJA1083 NXP Semiconductors FlexRay node transceiver If SCSN remains LOW for longer than 16 clock cycles, it is recognized as an SPI error. When this happens, the SPI error flag is set and pin SDO goes to a high-impedance state until the next falling edge on pin SCSN. An SPI error is also assumed if fewer than 16 clock cycles are received while SCSN is LOW. If this happens, the SPI error flag is set. All status bits are refreshed once the status register has been successfully read. When the transceiver is in simple error indication mode the SDO output is in a high-impedance state and pin SCSN is in pull-down mode. In SPI mode pin SCSN is in pull-up mode. SPI readout is not possible when the transceiver has detected an undervoltage on VIO.

A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 13.1 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. 13.2 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 13.3 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 TJA1083 Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 1 — 10 October 2012 © NXP B.V. 2012. All rights reserved. 31 of 41 TJA1083 NXP Semiconductors FlexRay node transceiver 13.4 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 18) 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 13 and 14 Table 13. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350  350 < 2.5 235 220  2.5 220 220 Table 14.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 18.

Appendix 14.1 Differences between TJA1082 and TJA1083 The main differences between the TJA1083 and the TJA1082 are: • The TJA1083 is EPL V3.0.1 compliant whereas the TJA1082 is EPL V2.1 Rev. B compliant • • • • TJA1083 Product data sheet The TJA1083 is JASPAR compliant (minimum transmitter output voltage of 900 mV) The TJA1083 has a higher pulse immunity (ISO7637) The TJA1083 has improved EMC behavior The bus load conditions for the static and dynamic characteristics are different in EPL V3.0.1 compared to EPL V2.1 Rev. B: 40  to 55  for the static characteristics instead of 40  and 40  for the dynamic characteristics instead of 45 . All information provided in this document is subject to legal disclaimers.
