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:

  • 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 independant 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 sub-system levels

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.

Features

General

  • Dedicated low dropout voltage regulator for the CAN-bus:
    • Independent from microcontroller supply
    • Guarded by CAN-bus failure management
    • Significantly improves EMC performance

LIN transceiver

  • LIN 2.0 compliant LIN transceiver
  • Enhanced error signalling and reporting
  • Downward compatible with LIN 1.3 and the TJA1020

Power management

  • Smart operating modes and power management modes
  • Cyclic wake-up capability in Standby and Sleep mode
  • Local wake-up input with cyclic supply feature
  • Remote wake-up capability via the CAN-bus and LIN-bus
  • External voltage regulators can easily be incorporated in the power supply system (flexible and fail-safe)
  • 42 V battery related high-side switch for driving external loads such as relays and wake-up switches
  • Intelligent maskable interrupt output

Fail-safe features

  • Safe and predictable behavior under all conditions
  • Programmable fail-safe coded window and time-out watchdog with on-chip oscillator, guaranteeing autonomous fail-safe system supervision
  • Fail-safe coded 16-bit SPI interface for the microcontroller
  • Global enable pin for the control of safety critical hardware
  • Detection and detailed reporting of failures:
    • On-chip oscillator failure and watchdog alerts
    • Voltage regulator undervoltages
    • CAN and LIN-bus failures (short-circuits and open-circuit bus wires)
    • TXD and RXD clamping situations and short-circuits
    • Clamped or open reset line
    • SPI message errors
    • Overtemperature warning
    • ECU ground shift (two selectable thresholds)
  • Rigorous error handling based on diagnostics
  • 23 bits of access-protected RAM is available e.g. for logging of cyclic problems
  • Reporting in a single SPI message; no assembly of multiple SPI frames needed
  • Limp home output signal for activating application hardware in case system enters Fail-safe mode (e.g. for switching on warning lights)
  • Fail-safe coded activation of Software development mode and Flash mode
  • Unique SPI readable device type identification
  • Software initiated system reset
