The TCANC3403-Q1 and TCANC3404-Q1 are 3.3V controller area network (CAN) FD transceivers that are compatible with the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification.
The transceivers have certified electromagnetic compatibility (EMC) operation for use with classical CAN and CAN FD networks up to 5 megabits per second (Mbps). Up to 8Mbps operation in simpler networks is possible with these devices. The TCANC3403-Q1 includes an internal logic level translation through the VIO pin, allowing the direct interface of the transceiver I/Os to 1.8V, 2.5V, or 3.3V logic levels. The TCANC3404-Q1 has shutdown feature where all blocks are powered off and device enters ultra-low power consumption mode. The transceivers support a low-power standby mode, and a wake over CAN which is compliant to the ISO 11898-2:2016 defined wake-up pattern (WUP).
The transceivers include thermal-shutdown (TSD), TXD-dominant time-out (DTO) and supply undervoltage detection. The devices have defined fail-safe behavior in supply undervoltage or floating pin scenarios. These devices are available in industry-standard SOIC-8, the VSON-8, and a space-saving small footprint SOT-23 packages.

The TCAN-SOIC8-EVM was developed to provide users the option to evaluate any Texas Instruments 8-pin CAN transciever device. The board provides evaluation flexibility with component footprint and jumper options.
The EVM comes with the TCAN332 CAN transceiver factory installed. The CAN EVM may be reconfigured by a user for use with all TI CAN transceiver families: SN65HVD23x, SN65HVD25x, SN65HVD10x0 and SN65HVDA54x by replacing the transceiver and setting jumpers on the EVM. The EVM has configurations (...)
This design is a low-power and small form factor reference design based on AWRL6432, TI's singlechip 60GHz automotive radar sensor. The design uses high RF performance PCB material and is targeted for in-cabin sensing end applications like child presence detection (CPD) and intruder detection (ID). (...)
