TCAN4550RGYTQ1

Overview

The TCAN4550RGYTQ1 is an automotive system basis chip featuring an integrated CAN FD controller and transceiver. It supports data rates up to 8 Mbps with a maximum SPI clock of 18 MHz, complying with ISO 11898-1:2015 and ISO 11898-2:2016 standards. The device includes a built-in LIN transceiver for body network communication. It operates within a temperature range of -40°C to 125°C and is qualified to AEC-Q100 standards. The component is housed in a 20-VQFN package measuring 3.5x4.5 mm.

Feature Summary

• Integrated CAN FD controller and transceiver supporting up to 8 Mbps data rates
• Built-in LIN transceiver for low-speed body network connectivity
• AEC-Q100 qualified for automotive applications (-40°C to 125°C)
• SPI interface with clock speeds up to 18 MHz

Applications

• Automotive electronic control units (ECUs)
• Gateway systems requiring CAN FD and LIN integration
• Industrial transport control systems

Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification. Ensure the 20-VQFN package matches the target PCB footprint dimensions of 3.5x4.5 mm. Confirm surface-mount compatibility with wettable flank requirements for inspection reliability during assembly processes.

Selection Notes

Select this component when a single IC must handle both high-speed CAN FD and low-speed LIN communications. It is suitable for microcontrollers lacking native CAN FD peripherals. Verify that the system power supply accommodates the required voltage levels for the integrated regulator and bus fault protection specifications.

Part Context

This part belongs to the Texas Instruments TCAN4550 family of system basis chips. The 'Q1' designation indicates automotive-grade qualification under AEC-Q100 standards. It serves as a consolidated solution for vehicle networks, replacing separate CAN FD controllers and transceivers to reduce board space and design complexity.

Replacement Considerations

Check for TCAN4550RGYRQ1 or TCAN4550RGYT variants depending on packaging preference. Ensure functional equivalence regarding pinout and register compatibility before substitution.
