It integrates the hub repeater, transaction translator, and port power management logic in a single 28-pin QFN package. The supply range spans 3.15V to 5.25V, which covers both 3.3V and 5V USB VBUS rails — useful for designs that need to run the controller directly off the bus voltage without an extra regulator. It is not rated for industrial or automotive under-hood use. ## 28-QFN footprint — exposed pad needs via stitching The CY7C65642-28LTXC comes in a 28-WFQFN with exposed pad (5x5 mm body). Without proper thermal management, the part may exceed its rated temperature range in a multi-port hub drawing several hundred milliamps. ## Active lifecycle — no end-of-life concern for new builds No official successor part has been announced.","metaTitle":"CY7C65642-28LTXC USB 2.0 Controller, HX2VL TetraHub, 28-QFN","metaDescription":"Infineon CY7C65642-28LTXC USB 2.0 hub controller, 3.15V-5.25V supply, 0°C-70°C, 28-QFN.","metaKeywords":null},"attributes":{"series":"HX2VL TetraHub™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"HX2VL TetraHub™","Package":"Tray","Function":"Controller","Protocol":"USB","Interface":"I²C, SPI","Standards":"USB 2.0","Package / Case":"28-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 5.25V","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"28-QFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.81000","currency":"USD"},{"qty":10,"price":"$5.21900","currency":"USD"},{"qty":25,"price":"$4.93360","currency":"USD"},{"qty":80,"price":"$4.27575","currency":"USD"},{"qty":230,"price":"$4.05652","currency":"USD"},{"qty":490,"price":"$3.63990","currency":"USD"},{"qty":980,"price":"$3.06980","currency":"USD"},{"qty":2450,"price":"$2.91631","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e45302a8b882f10880a7da8b6c37a788.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C65642-28LTXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C65642-28LTXC when reusing this data.
