UJA1061 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 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 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 compliant fault-tolerant CAN transceiver, interoperable with TJA1054, TJA1054A and TJA1055 LIN transceiver compliant with LIN 2.0 and SAE J2602, and compatible 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 common ECU functions in a single package, the fail-safe SBC offers an intelligent combination 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 combination with a microcontroller that incorporates a CAN controller. ...
