- No Longer Manufactured
- UJA1161TK
Self-Supplied High-Speed CAN Transceiver with Standby Mode
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
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.
