Functional description
6.1 Introduction
The UJA1065 combines all peripheral functions around a microcontroller within typical
automotive networking applications into one dedicated chip. The functions are as follows:
Power supply for the microcontroller
Power supply for the CAN transceiver
Switched BAT42 output
System reset
Watchdog with Window mode and Time-out mode
On-chip oscillator
High-speed CAN and LIN transceivers for serial communication; suitable for 12 V,
24 V and 42 V applications
SPI control interface
Local wake-up input
Inhibit or limp home output
System inhibit output port
Compatibility with 42 V power supply systems
Fail-safe behavior
6.2 Fail-safe system controller
The fail-safe system controller is the core of the UJA1065 and is supervised by a
watchdog timer which is clocked directly by the dedicated on-chip oscillator. The system
controller manages the register configuration and controls all internal functions of the
SBC. Detailed device status information is collected and presented to the microcontroller.
The system controller also provides the reset and interrupt signals.
The fail-safe system controller is a state machine. The different operating modes and the
transitions between these modes are illustrated in
Figure 3
. The following sections give
further details about the SBC operating modes.
