UJA1066TW/5V0/T General Description

The UJA1066 fail-safe System Basis Chip (SBC) replaces basic discrete components which are common in every Electronic Control Unit (ECU) with a Controller Area Network (CAN) interface. The fail-safe SBC supports all networking applications that control various power and sensor peripherals by using high-speed CAN as the main network interface. The fail-safe SBC contains the following integrated devices:High-speed CAN transceiver, interoperable and downward compatible with CAN transceiver TJA1041 and TJA1041A, and compatible with the ISO 11898-2 standard and the ISO 11898-5 standard (in preparation)Advanced independent watchdogDedicated voltage regulators for microcontroller and CAN transceiverSerial peripheral interface (full duplex)Local wake-up input portInhibit/limp-home output portIn addition to the advantages of integrating these common ECU functions in a single package, the fail-safe SBC offers an intelligent combination of system-specific functions such as:Advanced low-power conceptSafe and controlled system start-up behaviorAdvanced fail-safe system behavior that prevents any conceivable deadlockDetailed status reporting on system and subsystem levelsThe UJA1066 is designed to be used in combination 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 a full monitoring and software-driven fallback operation.The UJA1066 is designed for 14 V single power supply architectures and for 14 V and 42 V dual power supply architectures.
