Fault-tolerant CAN/LIN fail-safe system basis chip Rev. 06 - 9 March 2010 Product data sheet 1. General description The UJA1061 fail-safe System Basis Chip (SBC) replaces basic discrete ponents that are mon in every Electronic Control Unit (ECU) with a Controller Area Network (CAN) and a Local Interconnect Network (LIN) interface. The fail-safe SBC supports all networking applications that control various power and sensor peripherals by using fault-tolerant CAN as the main network interface and LIN as a local sub-bus. The fail-safe SBC contains the following integrated devices: - ISO11898-3 pliant fault-tolerant CAN transceiver, interoperable with TJA1054, TJA1054A and TJA1055 - LIN transceiver pliant with LIN 2.0 and SAE J2602, and patible with LIN 1.3 - Advanced independent watchdog - Dedicated voltage regulators for microcontroller and CAN transceiver - Serial peripheral interface (full duplex) - Local wake-up input port - Inhibit/limp-home output port In addition to the advantages of integrating these mon ECU functions in a single package, the fail-safe SBC offers an intelligent bination of system-specific functions such as: - Advanced low-power concept - Safe and controlled system start-up behavior - Advanced fail-safe system behavior that prevents any conceivable deadlock - Detailed status reporting on system and subsystem levels The UJA1061 is designed to be used in bination with a microcontroller that incorporates a CAN controller. The fail-safe SBC ensures that the microcontroller is always started up in a defined manner. In failure situations, the fail-safe SBC will maintain microcontroller functionality for as long as possible to provide full monitoring and a software-driven fall-back operation. The UJA1061 is designed for 14 V single power supply architectures and for 14 V and 42 V dual power supply architectures. NXP Semiconductors Fault-tolerant CAN/LIN fail-safe system basis chip 2.
