It integrates a USB 2.0 hub with an I²C and SPI control interface, allowing the host to configure port power, overcurrent reporting, and other hub parameters without extra GPIO pins. The supply voltage range of 3.15V to 5.25V covers both 3.3V and 5V USB rails, so a single regulator can feed the controller and the downstream port power switches. The 28-QFN package (5x5 mm) with exposed pad helps thermal dissipation when driving multiple ports at full current. ## Temperature grade limits deployment If the design must operate outside 0°C to 70°C, look at the industrial-temperature variants in the TetraHub family. ROHS3 compliance is confirmed.","metaTitle":"Infineon CY7C65642-28LTXCT USB 2.0 Hub Controller, 28-QFN","metaDescription":"Infineon CY7C65642-28LTXCT HX2VL TetraHub USB 2.0 hub controller. 3.15V–5.25V supply, I²C/SPI interface, 28-QFN.
