The UJA1065 fail-safe System Basis Chip (SBC) replaces basic discrete components that are common 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 high-speed CAN as the main network interface and LIN as a local sub-bus. The fail-safe SBC contains the following integrated devices:
In 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:
The UJA1065 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 full monitoring and a software-driven fall-back operation.
The UJA1065 is designed for 14 V single power supply architectures and for 14 V and 42 V dual power supply architectures.
