TJA1051 High-speed CAN transceiver Rev. 5 — 29 December 2010 Product data sheet 1. General description The TJA1051 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 applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJA1051 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 TJA1050. 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 • TJA1051T/3 and TJA1051TK/3 can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V These features make the TJA1051 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.

Functional description The TJA1051 is a high-speed CAN stand-alone 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. The TJA1051 is available in three versions, distinguished only by the function of pin 5: • The TJA1051T is 100 % backwards compatible with the TJA1050 • The TJA1051T/3 and TJA1051TK/3 allow for direct interfacing to microcontrollers with supply voltages down to 3 V • The TJA1051T/E allows the transceiver to be switched to a very low-current Off mode. 7.1 Operating modes The TJA1051 supports two operating modes, Normal and Silent, which are selected via pin S. An additional Off mode is supported in the TJA1051T/E via pin EN. See Table 4 for a description of the operating modes under normal supply conditions. Table 4. Operating modes Mode Inputs Outputs Pin EN[1] Pin S Pin TXD CAN driver Pin RXD HIGH LOW LOW dominant active[2] HIGH LOW HIGH recessive active[2] Silent HIGH HIGH X[3] recessive active[2] Off[1] LOW X[3] X[3] floating floating Normal [1] Only available on the TJA1051T/E. [2] LOW if the CAN bus is dominant, HIGH if the CAN bus is recessive. [3] ‘X’ = don’t care. 7.1.1 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 ElectroMagnetic Emission (EME). 7.1.2 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.

All rights reserved. 5 of 21 TJA1051 NXP Semiconductors High-speed CAN transceiver 7.1.3 Off mode A LOW level on pin EN of TJA1051T/E selects Off mode. In Off mode the entire transceiver is disabled, allowing the microcontroller to save power when CAN communication is not required. The bus pins are floating in Off mode, making the transceiver invisible to the rest of the network. 7.2 Fail-safe features 7.2.1 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. 7.2.2 Internal biasing of TXD, S and EN input pins Pin TXD has an internal pull-up to VIO and pins S and EN (TJA1051T/E) have internal pull-downs to GND. This ensures a safe, defined state in case one or more of these pins is left floating. 7.2.3 Undervoltage detection on pins VCC and VIO Should VCC or VIO drop below their respective undervoltage detection levels (Vuvd(VCC) and Vuvd (VIO); see Table 7), the transceiver will switch off and disengage from the bus (zero load) until VCC and VIO have 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), 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. 7.3 VIO supply pin There are three versions of the TJA1051 available, only differing in the function of a single pin. Pin 5 is either an enable control input (EN), a VIO supply pin or is not connected. Pin VIO on the TJA1051T/3 and TJA1051TK/3 should be connected to the microcontroller supply voltage (see Figure 6). This will adjust the signal levels of pins TXD, RXD and S to the I/O levels of the microcontroller. For versions of the TJA1051 without a VIO pin, the VIO input is internally connected to VCC. This sets the signal levels of pins TXD, RXD and S to levels compatible with 5 V microcontrollers.

Handling information All input and output pins are protected against ElectroStatic Discharge (ESD) under normal handling. 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.

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. 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 10.
