UJA1069TW/5V0/C/T, 1. General description

The UJA1069 fail-safe System Basis Chip (SBC) replaces basic discrete componentswhich are common in every Electronic Control Unit (ECU) with a Local InterconnectNetwork (LIN) interface. The fail-safe SBC supports all networking applications whichcontrol various power and sensor peripherals by using LIN as a local sub-bus. Thefail-safe SBC contains the following integrated devices:
• LIN transceiver compliant with LIN 2.0 and SAE J2602, and compatible with LIN 1.3
• Advanced independent watchdog
• Dedicated voltage regulator for microcontroller
• Serial peripheral interface (full duplex)
• Local wake-up input port
• Inhibit/limp-home output portIn addition to the advantages of integrating these common ECU functions in a singlepackage, the fail-safe SBC offers an intelligent combination of system-specific functionssuch 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 sub-system levelsThe UJA1069 is designed to be used in combination with a microcontroller and a LINcontroller. The fail-safe SBC ensures that the microcontroller is always started up in adefined manner. In failure situations the fail-safe SBC will maintain the microcontrollerfunction for as long as possible, to provide full monitoring and software driven fall-backoperation.The UJA1069 is designed for 14 V single power supply architectures and for 14 V and42 V dual power supply architectures.
