TJF1051 High-speed CAN transceiver Rev. 01 — 10 August 2010 Product data sheet 1. General description The TJF1051 is a 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 industrial applications, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJF1051 is a step up from the TJA1050 high-speed CAN transceiver. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features ideal passive behavior to the CAN bus when the supply voltage is off. The TJF1051 can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V These features make the TJF1051 an excellent choice for all types of HS-CAN networks, in nodes that do not require a standby mode with wake-up capability via the bus. 2. Features and benefits 2.1 General Fully ISO 11898-2 compliant Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI) VIO input allows for direct interfacing with 3 V to 5 V microcontrollers 2.2 Low-power management Functional behavior predictable under all supply conditions Transceiver disengages from the bus when not powered up (zero load) 2.3 Protection High ESD handling capability on the bus pins Transmit Data (TXD) dominant time-out function Undervoltage detection on pins VCC and VIO Thermally protected TJF1051 NXP Semiconductors High-speed CAN transceiver 3.

Functional description The TJF1051 is a stand-alone high-speed CAN transceiver with Silent mode. It combines the functionality of the TJA1050 transceiver with improved EMC and ESD handling capability. Improved slope control and high DC handling capability on the bus pins provides additional application flexibility. 6.1 Operating modes The TJF1051 supports two operating modes, Normal and Silent, which are selectable via pin S. See Table 3 for a description of the operating modes under normal supply conditions. Table 3. Operating modes Mode Inputs Normal Silent Outputs Pin S Pin TXD CAN driver Pin RXD LOW LOW dominant active[1] LOW HIGH recessive active[1] HIGH X[2] recessive active[1] [1] LOW if the CAN bus is dominant, HIGH if the CAN bus is recessive. [2] X = don't care. 6.1.1 Normal mode A LOW level on pin S selects Normal mode. In this mode, the transceiver is able to transmit and receive data via the bus lines CANH and CANL (see Figure 1 for the block diagram). The differential receiver converts the analog data on the bus lines into digital data which is output to pin RXD. The slope of the output signals on the bus lines is controlled and optimized in a way that guarantees the lowest possible EME levels. 6.1.2 Silent mode A HIGH level on pin S selects Silent mode. In Silent mode the transmitter is disabled, releasing the bus pins to recessive state. All other IC functions, including the receiver, continue to operate as in Normal mode. Silent mode can be used to prevent a faulty CAN controller from disrupting all network communications. 6.2 Fail-safe features 6.2.1 TXD dominant time-out function A ‘TXD dominant time-out’ timer is started when pin TXD is set LOW. If the LOW state on pin TXD 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 TXD is set HIGH. The TXD dominant time-out time also defines the minimum possible bit rate of 40 kbit/s. 6.2.2 Internal biasing of TXD and S input pins Pin TXD has an internal pull-up to VIO and pin S has an internal pull-down to GND. This ensures a safe, defined state in case one or both of these pins are left floating. TJF1051 Product data sheet All information provided in this document is subject to legal disclaimers.

If the virtual junction temperature exceeds the shutdown junction temperature, Tj(sd), the output drivers will be disabled until the virtual junction temperature falls below Tj(sd) and TXD becomes recessive again. Including the TXD condition ensures that output driver oscillations due to temperature drift are avoided. 6.3 VIO supply pin Pin VIO should be connected to the microcontroller supply voltage (see Figure 3). This adjusts the signal levels on pins TXD, RXD and S to the I/O levels of the microcontroller. 7.

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”. 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 TJF1051 Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 11 of 16 TJF1051 NXP Semiconductors High-speed CAN 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 7) 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 8 and 9 Table 8. 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 9.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 7.
