Automotive CAN Signal Improvement Capable transceiver with partial networking via selective wake

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.
