TJA1043 High-speed CAN transceiver Rev. 6 — 10 November 2017 Product data sheet 1. General description The TJA1043 high-speed CAN transceiver 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 CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJA1043 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 TJA1041A. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, very low power consumption, and passive behavior when the supply voltage is turned off. Advanced features include: • Low-power management controls the power supply throughout the node while supporting local and remote wake-up with wake-up source recognition • Several protection and diagnostic functions including bus line short-circuit detection and battery connection detection • Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V The TJA1043 implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. These features make the TJA1043 the ideal choice for high speed CAN networks containing nodes that need to be available all times, even when the internal VIO and VCC supplies are switched off. 2.

Improved slope control and high DC handling capability on the bus pins provide additional application flexibility. 7.1 Operating modes The TJA1043 supports five operating modes. Control pins STB_N and EN are used to select the operating mode. Switching between modes allows access to a number of diagnostics flags via pin ERR_N. Table 4 describes how to switch between modes. Figure 4 illustrates the mode transitions when VCC, VIO and VBAT are valid. Table 4.
