It also includes a UART interface for serial legacy device support. It comes in a 32-VFQFN exposed-pad package measuring 5x5 mm, making it suitable for space-constrained embedded designs that need a USB-connected I²C bus for sensor hubs, GPIO expanders, or configuration EEPROMs. ## Supply voltage flexibility and logic-level matching The 1.71V to 5.5V supply range is the headline BOM decision point. It lets the bridge run directly from a 1.8V, 2.5V, 3.3V, or 5V rail without an external LDO, which simplifies the power tree. The I²C bus voltage follows VCC, so a 1.8V supply means the SDA/SCL lines swing 1.8V — no level shifter needed when talking to a 1.8V sensor. At 5V the bus drives legacy 5V peripherals. That same wide range covers battery-powered gear where the rail droops under load. ## Industrial temperature grade and deployment At 20 mA supply current the die stays cool, but the pad still helps with mechanical stability during reflow. It is ROHS3 compliant.","metaTitle":"CY7C65215-32LTXI USB to I²C Bridge, 32-QFN, Active","metaDescription":"Infineon CY7C65215-32LTXI USB 2.0 to I²C bridge in 32-QFN (5x5 mm). 1.71V to 5.5V supply, -40°C to 85°C.
