It integrates the hub repeater, upstream facing port, and four downstream facing ports into a single 100-VFBGA package. The on-chip ROM (32 kB) holds the hub firmware; the 16K x 8 RAM supports per-port status and descriptor tables. An I2C interface allows an external host or EEPROM to override default configuration — useful for custom vendor IDs, port power sequencing, or compound-device descriptors. ## Lifecycle and sourcing For a BOM line that needs a USB 3.0 hub controller with an ARM core and I2C configuration, this part is a current-design fit.","metaTitle":"Cypress CYUSB3314-BVXI USB 3.0 Hub Controller, HX3 Series","metaDescription":"Cypress CYUSB3314-BVXI HX3 USB 3.0 hub controller, 4-port, ARM Cortex-M0, industrial temp -40 to 85°C, 100-VFBGA.
