8.1 Overview

The TCAN1476-Q1 devices meets or exceed the specifications of the Annex A Signal Improvement Capability (SIC) specification of ISO 11898-2:2024 Controller Area Network physical layer standard. The devices are data rate agnostic making them backward compatible for supporting classic CAN (CAN CC) applications while also supporting CAN FD networks up to 8Mbps. These devices have standby mode support which puts the CAN channel in ultra-low current consumption mode. Upon receiving valid wake-up pattern (WUP) on the CAN bus, the device signals to the microcontroller through the RXD pin. The MCU can then put the channel into normal mode using the STB pin.

The TCAN1476-Q1 has two separate bus-side supply rails, VCC1 and VCC2. The TCAN1476V-Q1 has two separate supply rails, VCC bus-side supply and VIO logic supply for logic-level translation for interfacing directly to 1.8V, 2.5V, 3.3V, or 5V controllers.
