TCAN1469-Q1

The TCAN146x-Q1 is a family of enhanced high-speed, CAN FD transceivers that meet the physical layer requirements of the ISO 11898-2:2024 Annex A for high speed CAN specification and the CiA 601-4 Signal Improvement (SIC) specification supporting data rates up to 8Mbps. The devices are configured using serial peripheral interface (SPI) for access to full functionality. The devices support nominal processor IO voltages from 1.8V to 5V by applying the appropriate voltage to the VIO pin, allowing lower power processors to be used.

These transceivers support selective wake (being able to wake-up based on WUF identification). This 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 TCAN1469-Q1 is a full featured devices supporting watchdog and advanced bus diagnostics. For ease of debug, the advanced bus fault diagnostics and communication feature can be used to determine specific bus faults.

The TCAN146x-Q1 is a family of enhanced high-speed CAN FD SIC transceivers. The devices are register compatible within the family and with TCAN114x-Q1 family of CAN FD Partial Networking transceivers. The TCAN146x-Q1 family of devices provide system designers the flexibility to implement features without hardware modifications, and with minimal software changes. The TCAN1469-Q1 inhibit (INH) pin can be used to either enable node power or to be configured as a limp home pin when a watchdog error takes place.
