General description The TJA1048 is a dual high-speed CAN transceiver that provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed (up to 1 Mbit/s) CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJA1048 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1040. It offers improved Electro Magnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features: * Ideal passive behavior to the CAN bus when the supply voltage is off * A very low-current Standby mode with bus wake-up capability on both channels * TJA1048T can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V These features make the TJA1048 an excellent choice for all types of HS-CAN networks containing more than one HS-CAN interface that require a low-power mode with wake-up capability via the CAN bus, especially for Body Control and Gateway units. 2.

Functional description The TJA1048 is a dual HS-CAN stand-alone transceiver with Standby mode and robust ESD handling capability. It combines the functionality of two TJA1040/TJA1042 transceivers with improved EMC and quiescent current performance. Improved slope control and high DC handling capability on the bus pins provide additional application flexibility. 7.1 Operating modes The TJA1048 supports two operating modes per transceiver, Normal and Standby. The operating mode can be selected independently for each transceiver via pins STBN1 and STBN2 (see Table 4). Table 4. Mode Operating modes Pin STBN1/STBN2 Pin RXD1/RXD2 LOW HIGH Normal HIGH bus dominant bus recessive Standby LOW wake-up request detected no wake-up request detected 7.1.1 Normal mode A HIGH level on pin STBN1/STBN2 selects Normal mode. In this mode, the transceiver can transmit and receive data via the bus lines CANH1/CANL1 and CANH2/CANL2 (see Figure 1 for the block diagram). The differential receiver converts the analog data on the bus lines into digital data which is output on pin RXD1/RXD2. The slope of the output signals on the bus lines is controlled and optimized in a way that guarantees the lowest possible EME. 7.1.2 Standby mode A LOW level on pin STBN1/STBN2 selects Standby mode. In Standby mode, the transceiver is not able to transmit or correctly receive data via the bus lines. The transmitter and Normal-mode receiver blocks are switched off to reduce supply current, and only a low-power differential receiver monitors the bus lines for activity. In Standby mode, the bus lines are biased to ground to minimize the system supply current. The low-power receiver is supplied by VIO, and is capable of detecting CAN bus activity even if VIO is the only supply voltage available. When pin RXD1/RXD2 goes LOW to signal a wake-up request, a transition to Normal mode will not be triggered until STBN1/STBN2 is forced HIGH. A dedicated wake-up sequence (specified in ISO11898-5) must be received to wake-up the TJA1048 from a low-power mode. This filtering is necessary to avoid spurious wake-up events due to a dominant clamped CAN bus or dominant phases caused by noise or spikes on the bus. A valid wake-up pattern consists of: A dominant phase of at least twake(busdom) followed by A recessive phase of at least twake(busrec) followed by A dominant phase of at least twake(busdom) TJA1048 Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 5 of 21 TJA1048 NXP Semiconductors Dual high-speed CAN transceiver with Standby mode The complete dominant-recessive-dominant pattern must be received within tto(wake)bus to be recognized as a valid wake-up pattern (see Figure 4). Pin RXD1/RXD2 will remain recessive until the wake-up event has been triggered. After a wake-up sequence has been detected, the TJA1048 will remain in Standby mode with the bus signals reflected on RXD1/RXD2. Note that dominant or recessive phases lasting less than tfltr(wake)bus will not be detected by the low-power differential receiver and will not be reflected on RXD1/RXD2 in Standby mode. A wake-up event will not be registered if any of the following events occurs while a wake-up sequence is being transmitted: The TJA1048 switches to Normal mode The complete wake-up pattern was not received within tto(wake)bus A VIO undervoltage is detected (VIO < Vuvd(VIO); see Section 7.2.3) If any of these events occurs while a wake-up sequence is being received, the internal wake-up logic will be reset and the complete wake-up sequence will have to be re-transmitted to trigger a wake-up event. twake(busrec) CANHx VO(diff)bus CANLx twake(busdom) twake(busdom) RXDx tfltr(wake)bus tfltr(wake)bus tto(wake)bus 015aaa147 Fig 4. Wake-up timing 7.2 Fail-safe features 7.2.1 TXD dominant time-out function A 'TXD dominant time-out' timer is started when pin TXD1/TXD2 is set LOW. If the LOW state on this pin persists for longer than tto(dom)TXD, the transmitter is disabled, releasing the bus lines to recessive state. This function prevents a hardware and/or software application failure from driving the bus lines to a permanent dominant state (blocking all network communications). The TXD dominant time-out timer is reset when pin TXD1/TXD2 is set HIGH. The TXD dominant time-out time also defines the minimum possible bit rate of 40 kbit/s. The TJA1048 has two TXD dominant time-out timers that operate independently of each other. TJA1048 Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 6 of 21 TJA1048 NXP Semiconductors Dual high-speed CAN transceiver with Standby mode 7.2.2 Internal biasing of TXD1, TXD2, STBN1 and STBN2 input pins Pins TXD1 and TXD2 have internal pull-ups to VIO and pins STBN1 and STBN2 have internal pull-downs to GNDA and GNDB. This ensures a safe, defined state if any of these pins is left floating. Pins GNDA and GNDB must be connected together in the application. Pull-up/pull-down currents flow in these pins in all states. Pins TXD1 and TXD2 should be held HIGH in Standby mode to minimize standby currents; pins STBN1 and STBN2 should be held LOW. 7.2.3 Undervoltage detection on pins VCC and VIO Should VCC drop below the VCC undervoltage detection level, Vuvd(VCC), both transceivers will switch to Standby mode. The logic state of pins STBN1 and STBN2 will be ignored until VCC has recovered. Should VIO drop below the VIO undervoltage detection level, Vuvd(VIO), the transceivers will switch off and disengage from the bus (zero load) until VIO has recovered. 7.2.4 Overtemperature protection The output drivers are protected against overtemperature conditions. If the virtual junction temperature exceeds the shutdown junction temperature, Tj(sd), both output drivers will be disabled. When the virtual junction temperature drops below Tj(sd) again, the output drivers will recover independently once TXD1/TXD2 has been reset to HIGH. Including the TXD1/TXD2 condition prevents output driver oscillation due to small variations in temperature. 7.3 VIO supply pin Pin VIO should be connected to the microcontroller supply voltage (see Figure 5). This will adjust the signal levels of pins TXD1, TXD2, RXD1, RXD2, STBN1 and STBN2 to the I/O levels of the microcontroller. Pin VIO also provides the internal supply voltage for the transceiver's low-power differential receiver. For applications running in low-power mode, this allows the bus lines to be monitored for activity even if there is no supply voltage on pin VCC.

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: TJA1048 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 9 and 10 Table 9.
