TJA1054
The TJA1054 is the interface between the protocol controller and the physical bus wires in a Controller Area Network (CAN). It is primarily intended for low-speed applications up to 125 kBaud in passenger cars. The device provides differential receive and transmit capability but will switch to single-wire transmitter and/or receiver in error conditions. The TJA1054T is pin and downwards compatible with the PCA82C252T and the TJA1053T. This means that these two devices can be replaced by the TJA1054T with retention of all functions. The most important improvements of the TJA1054 with respect to the PCA82C252 and the TJA1053 are: * Very low EME due to a very good matching of the CANL and CANH output signals * Good EMI, especially in low power modes * Full wake-up capability during bus failures * Extended bus failure management including short-circuit of the CANH bus line to VCC * Support for easy system fault diagnosis * Two-edge sensitive wake-up input signal via pin WAKE.

FUNCTIONAL DESCRIPTION The TJA1054 is the interface between the CAN protocol controller and the physical wires of the CAN bus (see Fig.7). It is primarily intended for low speed applications, up to 125 kBaud, in passenger cars. The device provides differential transmit capability to the CAN bus and differential receive capability to the CAN controller. To reduce EME, the rise and fall slopes are limited. This allows the use of an unshielded twisted pair or a parallel pair of wires for the bus lines. Moreover, the device supports transmission capability on either bus line if one of the wires is corrupted. The failure detection logic automatically selects a suitable transmission mode. In normal operating mode (no wiring failures) the differential receiver is output on pin RXD (see Fig.1). The differential receiver inputs are connected to pins CANH and CANL through integrated filters. The filtered input signals are also used for the single-wire receivers. The receivers connected to pins CANH and CANL have threshold voltages that ensure a maximum noise margin in single-wire mode. A timer function (TxD dominant time-out function) has been integrated to prevent the bus lines from being driven into a permanent dominant state (thus blocking the entire network communication) due to a situation in which pin TXD is permanently forced to a LOW level, caused by a hardware and/or software application failure.
TJA1054
If the duration of the LOW level on pin TXD exceeds a certain time, the transmitter will be disabled. The timer will be reset by a HIGH level on pin TXD. Failure detector The failure detector is fully active in the normal operating mode. After the detection of a single bus failure the detector switches to the appropriate mode (see Table 1). The differential receiver threshold voltage is set at -3.2 V typical (VCC = 5 V). This ensures correct reception with a noise margin as high as possible in the normal operating mode and in the event of failures 1, 2, 5 and 6a. These failures, or recovery from them, do not destroy ongoing transmissions. The output drivers remain active, the termination does not change and the receiver remains in differential mode (see Table 1). Failures 3, 3a and 6 are detected by comparators connected to the CANH and CANL bus lines. Failures 3 and 3a are detected in a two-step approach. If the CANH bus line exceeds a certain voltage level, the differential comparator signals a continuous dominant condition. Because of inter-operability reasons with the predecessor products PCA82C252 and TJA1053, after a first time-out the transceiver switches to single wire operation through CANH. If the CANH bus line is still exceeding the CANH detection voltage for a second time-out, the TJA1054 switches to CANL operation; the CANH driver is switched off and the RTH bias changes to the pull-down current source. The time-outs (delays) are needed to avoid false triggering by external RF fields.

Failure 6 is detected if the CANL bus line exceeds its comparator threshold for a certain period of time. This delay is needed to avoid false triggering by external RF fields. After detection of failure 6, the reception is switched to the single wire mode through CANH; the CANL driver is switched off and the RTL bias changes to the pull-up current source. Recovery from failures 3, 3a and 6 is detected automatically after reading a consecutive recessive level by corresponding comparators for a certain period of time. Failures 4 and 7 initially result in a permanent dominant level on pin RXD. After a time-out the CANL driver is switched off and the RTL bias changes to the pull-up current source. Reception continues by switching to the single-wire mode via pins CANH or CANL. When failures 4 or 7 are removed, the recessive bus levels are restored. If the differential voltage remains below the recessive threshold level for a certain period of time, reception and transmission switch back to the differential mode. If any of the wiring failures occur, the output signal on pin ERR will be set to LOW. On error recovery, the output signal on pin ERR will be set to HIGH again. In case of an interrupted open bus wire, this failure will be detected and signalled only if there is an open wire between the Table 2 Normal operating and low power modes PIN STB LOW LOW LOW HIGH PIN EN HIGH LOW(3) LOW LOW VBAT power-on flag; notes 1 and 4 error flag no error flag wake-up interrupt signal; notes 1 and 2 dominant received data recessive received data PIN ERR LOW wake-up interrupt signal; notes 1 and 2 HIGH LOW wake-up interrupt signal; notes 1 and 2 PIN RXD HIGH

transmitting and receiving node(s). Thus, during open wire failures, pin ERR typically toggles. During all single-wire transmissions, EMC performance (both immunity and emission) is worse than in the differential mode. The integrated receiver filters suppress any HF noise induced into the bus wires. The cut-off frequency of these filters is a compromise between propagation delay and HF suppression. In single-wire mode, LF noise cannot be distinguished from the required signal. Low power modes The transceiver provides three low power modes which can be entered and exited via pins STB and EN (see Table 2 and Fig.3). The Sleep mode is the mode with the lowest power consumption. Pin INH is switched to high-impedance for deactivation of the external voltage regulator. Pin CANL is biased to the battery voltage via pin RTL. If the supply voltage is provided, pins RXD and ERR will signal the wake-up interrupt. The standby mode operates in the same way as the Sleep mode but with a HIGH level on pin INH.

The power-on standby mode is the same as the standby mode, however, in this mode the battery power-on flag is shown on pin ERR instead of the wake-up interrupt signal. The output on pin RXD will show the wake-up interrupt. This mode is only for reading out the power-on flag. Wake-up requests are recognized by the transceiver through two possible channels: * The bus lines for remote wake-up * Pin WAKE for local wake-up. In order to wake-up the transceiver remotely through the bus lines, a filter mechanism is integrated. This mechanism makes sure that noise and any present bus failure conditions do not result into an erroneous wake-up. Because of this mechanism it is not sufficient to simply pull the CANH or CANL bus lines to a dominant level for a certain time. To guarantee a successful remote wake-up under all conditions, a message frame with a dominant phase of at least the maximum specified tCANH or tCANL in it is required. A local wake-up through pin WAKE is detected by a rising or falling edge with a consecutive level with the maximum specified tWAKE. On a wake-up request the transceiver will set the output on pin INH to HIGH which can be used to activate the external supply voltage regulator. If VCC is present the wake-up request can be read on the ERR or RXD outputs, so the external microcontroller can activate the transceiver (switch to normal operating mode) via pins STB and EN. To prevent a false remote wake-up due to transients or RF fields, the wake-up voltage levels have to be maintained for a certain period of time. In the low power modes the failure detection circuit remains partly active to prevent an increased power consumption in the event of failures 3, 3a, 4 or 7. To prevent a false local wake-up during an open wire at pin WAKE, this pin has a weak pull-up current source towards VBAT. Pin INH is set to floating only if the goto-sleep command is entered successfully. To enter a successful goto-sleep command under all conditions, this command must be kept stable for the maximum specified th(sleep).
TJA1054
Pin INH will be set to a HIGH level again by the following events only: * VBAT power-on (cold start) * Rising or falling edge on pin WAKE * A message frame with a dominant phase of at least the maximum specified tCANH or tCANL, while pin EN or pin STB is at a LOW level * Pin STB goes to a HIGH level with VCC active. To provide fail-safe functionality, the signals on pins STB and EN will internally be set to LOW when VCC is below a certain threshold voltage (VCC(stb)). Power-on After power-on (VBAT switched on) the signal on pin INH will become HIGH and an internal power-on flag will be set. This flag can be read in the power-on standby mode through pin ERR (STB = 1; EN = 0) and will be reset by entering the normal operating mode. Protection A current limiting circuit protects the transmitter output stages against short-circuit to positive and negative battery voltage. If the junction temperature exceeds the typical value of 165 C, the transmitter output stages are disabled. Because the transmitter is responsible for the major part of the power dissipation, this will result in a reduced power dissipation and hence a lower chip temperature. All other parts of the device will continue to operate. The pins CANH and CANL are protected against electrical transients which may occur in an automotive environment.

Mode 10 stands for: pin STB = HIGH and pin EN = LOW. (1) Mode change via input pins STB and EN. (2) Mode change via input pins STB and EN; it should be noted that in the sleep mode pin INH is inactive and possibly there is no VCC. Mode control is only possible if VCC of the transceiver is active. (3) Pin INH is activated after wake-up via bus or input pin WAKE. (4) Transitions to normal mode clear the internal wake-up: interrupt and battery fail flag are cleared. (5) Transitions to sleep mode: pin INH is deactivated.

SOLDERING Introduction to soldering surface mount packages This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 220 C for thick/large packages, and below 235 C for small/thin packages. Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed.
TJA1054
If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.

All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. not suitable not not not suitable(2) recommended(3)(4) recommended(5) suitable REFLOW(1) suitable suitable suitable suitable suitable
