It operates across three supply rails — 1.14V to 1.26V core, 2.5V to 2.7V, and 3V to 3.6V I/O — giving the board designer flexibility to match existing power trees without an extra regulator. The I²C interface allows the host to configure hub parameters or read status registers, which is useful for systems that need to disable ports on overcurrent or adjust charging-downstream current limits without a firmware update. ## Package, temperature, and board integration With 10 general-purpose I/O lines, the controller can drive status LEDs, reset signals, or port-power enable FETs directly, reducing the need for external GPIO expanders. RoHS3 compliant, with no halogen or lead restrictions that would block EU or California market entry.","metaTitle":"Infineon CYUSB3312-88LTXI HX3 USB 3.0 Hub Controller, 2-Port","metaDescription":"Infineon CYUSB3312-88LTXI HX3 2-port USB 3.0 hub controller with ARM Cortex-M0, 32KB ROM, I²C interface, -40 to 85°C, 88-QFN.
