The FE1.1S (SSOP, 28P) is a USB 2.0 High-Speed Hub Controller manufactured by Terminus Technology Inc. Identical in functionality to the FE1.1S-BSOP28BCN, but offered in a SSOP (Shrink Small Outline Package) with 28 pins. This allows expanding a single USB port into multiple downstream ports, enabling the connection of more USB devices. It fully supports USB 2.0 high-speed (480Mbps), full-speed (12Mbps) and low-speed (1.5Mbps) transfer rates.

Applications

• USB Hubs: Creation of stand-alone USB hubs for connectivity expansion.
• Laptop Docking Stations: Enhancing connectivity options for portable computers.
• Embedded Systems: Adding USB capabilities to diverse embedded applications.
• Computer Peripherals: Integration into devices like printers, scanners, and external hard drives.
• Automotive Infotainment: USB connectivity for multimedia and device charging in vehicles.

Features

• USB 2.0 Compliant: Supports high-speed (480Mbps), full-speed (12Mbps), and low-speed (1.5Mbps) data rates.
• Four Downstream Ports: Enables connections to four individual USB devices.
• Integrated Transceiver: Simplifies board design and reduces the external component count.
• Individual Port Power Switching: Independent power control for each downstream port, improving power efficiency.
• Over-Current Protection: Safeguards the hub and connected devices from potential damage.

Benefits

• Expanded Connectivity: Enables connection of multiple USB devices to a single host port.
• High-Speed Data Transfer: Facilitates rapid data transfer between connected devices and the host.
• Simplified Design: Reduces the complexity of circuit design and overall system costs.
• Power Efficiency: Optimizes power consumption through independent port power control.
• Robust Protection: Enhances system reliability through integrated over-current protection.
