NXP Semiconductors TJA144x CAN FD & TJA146x CAN SIC

The TJA1445, TJA1446, TJA1465 and  TJA1466 are part of NXP’s portfolio of highspeed CAN sleep mode transceivers which support partial networking by means of a selective wake up feature, as specified in ISO11898-2. All products are fully developed and certified to be ISO 26262 ASIL B compliant.

TJA1445 & TJA1446 CAN FD Partial Networking
The CAN FD transceivers with partial networking sleep mode, are part of the TJA144x transceiver family that implement CAN FD as defined in ISO11898-2:2024 parameter sets A-B. The TJA144x is fully interoperable with the high-speed classical CAN and CAN FD protocols. All variants offer a CAN FD passive feature which in sleep mode prevents the transceiver from waking up and shields the CAN controller from CAN FD messages when running a mixed bus communication.

TJA1465 & TJA1466 CAN SIC Partial Networking
The CAN SIC transceivers with partial networking sleep mode, are part of the TJA146x transceiver family that implement CAN SIC as defined in ISO11898-2:2024 parameter sets A-C. The TJA146x is fully interoperable with the high-speed classical CAN and CAN FD protocols. All variants offer a CAN FD/ CAN XL passive feature which in sleep mode prevents the transceiver from waking up and shields the CAN controller from CAN FD or CAN XL messages when running a mixed bus communication.

Key features
