1. General description
The UJA1061 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) and a Local Interconnect Network (LIN) interface. The fail-safe SBC supports all
networking applications which 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:
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 UJA1061 is designed to be used in combination with a microcontroller with 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 the microcontroller
function for as long as possible, to provide full monitoring and 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.
