This means the side of each pad is plated, so an AOI system can verify solder-joint wetting after reflow — a requirement in automotive assembly lines where hidden QFN joints are a common inspection blind spot. The datasheet's recommended footprint and stencil aperture pattern should be followed; the pad also serves as a ground return for the CAN bus transceiver section inside the controller. There is no LTB window to manage, and no official successor has been issued — this is the current production variant for the TCAN4550 base number.","metaTitle":"TCAN4550RGYRQ1 CAN FD Controller, AEC-Q100, 20-VQFN","metaDescription":"TI TCAN4550RGYRQ1 CAN FD Controller, AEC-Q100 qualified, 20-VQFN (3.5x4.5) package with wettable flank.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Type":"CAN FD Controller","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR)","Applications":"-","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TCAN4550","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6335","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1c8e2c8c39b3d4808fe53072eb4fa2cf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN4550RGYRQ1/alternatives.json"},"ai":{"faq":[{"question":"Does TCAN4550RGYRQ1 support CAN FD or only classical CAN?","answer":"The TCAN4550RGYRQ1 is a CAN FD controller, supporting both classical CAN (up to 1 Mbps) and CAN FD (up to 8 Mbps data phase) per the ISO 11898-1:2015 standard."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TCAN4550RGYRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TCAN4550RGYRQ1 when reusing this data.
