Overview
The TCAN4550RGYT, produced by Texas Instruments, is a CAN FD (Controller Area Network with Flexible Data Rate) controller integrated with a CAN FD transceiver. This device supports data rates up to 8 Mbps and is designed to meet the specifications of the ISO 11898-1:2015 high-speed CAN data link layer and the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. It provides an interface between the CAN bus and the system processor through a serial peripheral interface (SPI), supporting both classic CAN and CAN FD. This makes it versatile for use in various applications, including those requiring port expansion or CAN support with processors that do not natively support CAN FD.
