Introduction

The chip operates on a single 5V supply, with integrated 5V-to-3.3V and 3.3V-to-1.2V voltage conversion, requiring only external filter capacitors on the power supply. An on-chip reset circuit is included, and the device features a low-power design.

Features

• Full support for USB 2.0 High-Speed (480MHz), USB 1.1 Full-Speed (12MHz), and USB 1.0 Low-Speed (1.5MHz) modes
• Integrated one upstream port supporting HS/FS modes and four downstream ports supporting HS/FS/LS modes
• Integrated 12MHz to 480MHz PLL
• Multi-Transaction Translator technology with one Transaction Translator per downstream port, providing 12Mbps bandwidth per port when connected to Full-Speed devices
• Built-in 1.5Kohm upstream port pull-up resistors, 15Kohm downstream port pull-down resistors, and 45ohm high-speed termination resistors
• Hub implements one control endpoint and one interrupt endpoint
• Self-powered and bus-powered mode support
• BC1.2 charging protocol support
• Upstream port status indicator support
• Operating temperature range: -40°C to +85°C
