1. General description
The UJA1066 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) interface. The fail-safe SBC supports all networking applications that control
various power and sensor peripherals by using high-speed CAN as the main network
interface. 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 UJA1066 is designed to be used in combination with a microcontroller that
incorporates 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
microcontroller functionality for as long as possible to provide a full monitoring and
software-driven fallback operation.
The UJA1066 is designed for 14 V single power supply architectures and for 14 V and
42 V dual power supply architectures.

... NXP Semiconductors 6.2.1 Start-up mode Start-up mode is the ‘home page’ of the SBC. This mode is entered when battery and ground are connected for the first time. Start-up mode is also entered after any event that results in a system reset. The reset source information is provided by the SBC to support software initialization cycles that depend on the reset event ...

Page 10

... NXP Semiconductors Entering Normal mode does not activate the CAN transceiver automatically. The CAN Mode Control (CMC) bit must be set to activate the CAN medium if required, allowing local cyclic wake-up scenarios to be implemented without affecting the CAN-bus. 6.2.5 Standby mode In Standby mode, the system reduced current consumption state. Entering Standby mode overrides the CMC bit, allowing the CAN transceiver to enter the low-power mode autonomously ...

... NXP Semiconductors • Cyclic wake-up by the watchdog via an interrupt signal to the microcontroller (the microcontroller is triggered periodically and checked for the correct response) • Cyclic wake-up by the watchdog via a reset signal (a reset is performed periodically; the SBC provides information about the reset source to allow different start sequences after reset) • ...

NXP Semiconductors The following corrupted watchdog accesses result in an immediate system reset: • Illegal watchdog period coding; only ten different codes are valid • Illegal operating mode coding; only six different codes are valid Any microcontroller-driven mode change is synchronized with a watchdog access by reading the mode information and the watchdog period information from the same register ...

Page 14

... NXP Semiconductors The watchdog window is defined to be between 50 % and 100 % of the nominal programmed watchdog period. Any ‘too early’ or ‘too late’ watchdog access or incorrect Mode register code access will result in an immediate system reset, when the SBC will revert to Start-up mode. ...

Page 15

... NXP Semiconductors If the microcontroller supply current rises above I watchdog will be restarted using the watchdog period last used and, if enabled, a watchdog restart interrupt will be generated. In the case of a direct mode change to Standby with watchdog OFF selected, the longest possible watchdog period is used. It should be noted that V1 current monitoring is not active in Sleep mode ...

... NXP Semiconductors The behavior of pin RSTN is illustrated in setting of bit RLC (which defines the reset length). Once an external reset event has been detected, the system controller enters Start-up mode.
