Product details

Four-port USB 3.0 hub with on-chip management

The Cypress CYUSB3314-BVXI is a 4-port USB 3.0 hub controller from the HX3 series, built around an ARM Cortex-M0 core. 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.

Frequently asked questions

What is the replacement for CYUSB3314-BVXI?

No direct replacement is listed. The CYUSB3314-BVXI is the current active HX3 4-port hub controller. The CYPD2122-24LQXIT is a different device (USB Type-C controller with flash memory), not a functional substitute for a USB 3.0 hub.

Can CYUSB3314-BVXI be used in commercial temperature?

Yes. Its -40°C to 85°C rating covers commercial (0°C to 70°C) environments with margin. It is also suitable for industrial and outdoor telecom enclosures.
