The TCAN1476-Q1 is a dual, high speed Controller Area Network (CAN) SIC transceiver that meets the physical layer requirements of the ISO 11898-2:2024 Annex A Signal Improvement (SIC) specification. The device reduces signal ringing at dominant-to-recessive edge and enables higher throughput in complex network topologies. Signal improvement capability allows the applications to extract real benefit of CAN FD (flexible data rate) by being able to operate at 2Mbps, 5Mbps or even beyond in large networks with multiple unterminated stubs.
The device meets the timing specifications mandated by ISO 11898-2:2024 Annex A SIC mode specifications; thus, has much tighter bit timing symmetry compared to regular CAN FD transceivers. This provides larger timing window to sample the correct bit and enables error-free communication in large complex star networks where ringing and bit distortion are inherent.
This device is pin-compatible to 14-pin dual CAN FD transceivers, such as TCAN1046A-Q1 or TCAN1046AV-Q1.
The TCAN1476-Q1 devices with suffix "V" include internal logic level translation via the VIO logic supply terminal to allow for interfacing directly to 1.8V, 2.5V, or 3.3V controllers. The two CAN channels support independent mode control through the standby pins. Therefore, each transceiver can be placed into a low-power state, standby mode, without impacting the state of the other CAN channel. The low power standby mode allows remote wake-up via CAN bus compliant with ISO 11898-2:2024 defined wake-up pattern (WUP). The device also includes many protection features such as undervoltage detection, thermal shutdown (TSD), driver dominant timeout (TXD DTO), and ±58V bus fault protection.

This EVM can be used to evaluate the TCAN1046A and TCAN1046AV product in the D package. The CAN buses are easily accessed via test points, 100 mil headers, or a DB9 connector, and symmetrically laid out for optimal performance. All IC signals are available through jumper connections, and modes are (...)
