It integrates the USB transceiver and protocol stack, so the host sees a standard HID or vendor-class device — no driver development needed for basic enumeration. The UART interface is also available on the same pins, giving a second serial path for debug or legacy device connections. ## Supply range and current budget The 1.71 V to 5.5 V supply range lets this bridge run off a 1.71 V to 5.5 V rail. At 20 mA typical supply current, it stays within the USB 2.0 bus-powered hub budget. ## Temperature grade and environment Rated for -40°C to 85°C, this part fits industrial control cabinets, outdoor telecom enclosures, and engine-bay-adjacent electronics where the ambient can swing well beyond office temperature. The 24-QFN package (4x4 mm) with exposed pad helps conduct heat to the PCB ground plane — keep the thermal vias under the pad populated if you're running near the upper temperature limit.","metaTitle":"CY7C65211-24LTXI USB-to-I²C Bridge, 20mA, 1.71V-5.5V, 24-QFN","metaDescription":"Infineon CY7C65211-24LTXI USB-to-I²C bridge, USB 2.0, UART interface, 20mA supply, 1.71V-5.5V, -40°C to 85°C, 24-QFN.
