Automotive CAN FD Controller with Integrated Transceiver, SPI Interface (8 Mbps, VQFN-20)
The TCAN4551-Q1 combines a CAN FD controller and a CAN FD transceiver in one device, connected to the host processor via SPI (up to 18 MHz). It lets designers add CAN FD channels to MCUs or processors that have no or too few native CAN FD peripherals. It supports data rates up to 8 Mbps, ±58 V bus fault protection and 1.8 V / 3.3 V / 5 V I/O, and is AEC-Q100 Grade 1 qualified for –40 °C to 125 °C ambient.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
When should I use TCAN4551-Q1 instead of a standalone transceiver?
When the host MCU or SoC has no (or not enough) CAN FD controllers – the TCAN4551-Q1 adds a complete CAN FD channel over SPI.
Can Cerametronics supply TCAN4551RGYRQ1?
Yes. Send your quantity, date code requirement and schedule; we quote from traceable sources for production and shortage needs.
