3 Description

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.
