It handles upstream port negotiation, downstream port power management, and status reporting over an I²C interface. The 16K x 8 RAM and 32 kB ROM (program memory) support the hub's internal firmware and configuration storage. ## I²C interface — what it is for and what it is not The I²C interface on this hub is for configuration and status readback — setting port power switching, overcurrent response, and reading device status. It is not a general-purpose expansion bus for external peripherals; the 10 I/O lines are dedicated to hub control functions (port indicators, overcurrent detect, reset).","metaTitle":"Cypress CYUSB2304-68LTXIT USB 2.0 Hub Controller, 4-Port","metaDescription":"Cypress HX3 series USB 2.0 hub controller with ARM Cortex-M0, 4-port, I2C interface, -40 to 85°C.
