3 Description

The TCAN146x-Q1 is a family of enhanced highspeed,

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 highspeed

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.
