The TCAN157x-Q1 are enhanced high-speed, CAN FD SIC transceivers that meet the physical layer requirements of the ISO 11898-2:2024 (Annex A) for a high-speed CAN SIC specification supporting data rates up to 8Mbps. The devices are configured using SPI for access to full functionality. They support nominal processor IO voltages from 1.8V to 5V using the corresponding voltage on VIO, allowing the use of lower power processors.

These transceivers support selective wake (being able to wake-up based on WUF identification). The feature enables systems to implement partial networking and operate with a reduced number of nodes in an active state while the remaining nodes are in a low-power sleep mode. The transceivers and selective wake function meet the specifications of the ISO 11898-2:2024 standard.

The TCAN1576-Q1 is a full-featured device supporting watchdog and advanced bus diagnostics. For ease of debug, the advanced bus fault diagnostics and communication feature is used to determine specific bus faults.

The TCAN157x-Q1 are register compatible within the family and with TCAN1145-Q1 and TCAN1146-Q1 CAN FD Partial Networking transceivers. The TCAN157x-Q1 provides system designers the flexibility to implement features without hardware modifications, and with minimal software changes. The TCAN1576-Q1 inhibit (INH) pin is used to either enable node power or to be configured as a limp home pin when a watchdog error takes place.
