1. General description
The UJA1161 is a ‘self-supplied’ high-speed CAN transceiver integrating an
ISO 11898-2/5 compliant HS-CAN transceiver and an internal 5 V CAN supply. The only
supply input is a battery connection. The UJA1161 can be operated in a very low-current
Standby mode with bus wake-up capability.
The UJA1161 implements the standard CAN physical layer as defined in the current
ISO11898 standard (-2 and -5). Pending the release of the updated version of ISO11898
including CAN FD, additional timing parameters defining loop delay symmetry are
included. This implementation enables reliable communication in the CAN FD fast phase
at data rates up to 2 Mbit/s.
