TCAN4550RGYRQ1

Overview

The Texas Instruments TCAN4550RGYRQ1 is an automotive-grade CAN FD controller with an integrated transceiver, designed for high-speed communication up to 5 Mbps. It complies with ISO 11898-1:2015 and ISO 11898-2:2016 standards, supporting both classic CAN and CAN FD protocols. The device interfaces with system processors via a Serial Peripheral Interface (SPI) operating at clock speeds up to 18 MHz. Key features include local wake-up (LWU), bus wake-up capabilities, and robust protection mechanisms such as ±42V bus fault tolerance and ±12V common-mode range. It operates within a 3.3 V to 5.0 V logic supply and is housed in a 20-VQFN package.

Feature Summary

• Integrated CAN FD transceiver supporting data rates up to 5 Mbps
• Compliance with ISO 11898-1:2015 and ISO 11898-2:2016 specifications
• AEC-Q100 qualified for automotive applications
• SPI interface with clock speeds up to 18 MHz

Applications

• Building automation systems
• Factory automation and controls
• Industrial transport networks

Procurement Notes

Verify the specific suffix RGYRQ1 against official Texas Instruments documentation to confirm the exact tape and reel packaging configuration and temperature grade. Ensure that the AEC-Q100 qualification aligns with the specific reliability requirements of the target automotive application before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution combining a CAN FD controller and transceiver is required to reduce board space. It is suitable for designs needing ISO 11898-2:2016 compliance and robust fault protection. Consider the 20-VQFN package constraints and SPI interface timing requirements during the hardware design phase.

Part Context

This part belongs to the TCAN4550 family, which integrates a Bosch M_CAN-compatible controller with a high-speed CAN transceiver. The RGYRQ1 designation indicates the automotive grade variant, distinguished by its AEC-Q100 certification and specific packaging options like Tape & Reel for automated assembly processes.

Replacement Considerations

Direct replacements must match the 20-VQFN footprint and pinout. Verify compatibility with existing firmware drivers, as register maps may differ between manufacturers. Ensure the substitute supports the required 5 Mbps data rate and ISO 11898-2:2016 physical layer specifications.
