Overview
Equivalent
The FE1.1 (USB 2.0 hub controller) has several equivalents, including:
- GL850G (Genesys Logic)
- AU6254 (Alcor Micro)
- USB2512 (Microchip)
- TUSB2046B (Texas Instruments)
These chips offer similar USB 2.0 hub functionality with 4 ports. The GL850G is the most common drop-in replacement. For enhanced features, USB2512 or TUSB2046B are alternatives. Always check pin compatibility and voltage requirements.

Pinout
The FE1.1 is a USB 2.0 hub controller IC, typically available in a 28-pin SSOP package.
Key Functions:
- Supports 4 downstream ports (configurable as 1–4 ports).
- Operates at Full Speed (12 Mbps) or Low Speed (1.5 Mbps).
- Integrated 5V-to-3.3V regulator for power efficiency.
- Supports individual or ganged power switching for downstream ports.
- Features overcurrent detection and port disable/enable control.
Pin Highlights:
- VBUS, D+/D–: USB data/power lines.
- PWRCTL: Controls downstream power.
- OC#: Overcurrent detection input.
- XTAL1/XTAL2: External crystal oscillator (12 MHz).
The FE1.1 is commonly used in USB hub peripherals due to its simplicity and cost-effectiveness.

Manufacturer
The FE1.1 is a USB hub controller manufactured by Fresco Logic, a Taiwanese company specializing in USB and PCIe interface solutions. Founded in 2008, Fresco Logic develops high-performance connectivity chips for applications like USB hubs, docking stations, and Thunderbolt devices. The FE1.1 is an older, cost-effective USB 2.0 hub controller, commonly found in budget peripherals. Fresco Logic is known for its reliable but not cutting-edge technology, catering to mainstream and legacy markets.
Application
The FE1.1 is a USB 2.0 hub controller chip commonly used in:
1. USB Hubs – Expands single USB ports into multiple ports.
2. Peripheral Devices – Keyboards, mice, and external storage.
3. Industrial Equipment – Automation and control systems.
4. Consumer Electronics – Smart TVs, gaming consoles, and docking stations.
5. Embedded Systems – IoT devices and single-board computers.
It supports up to 4 downstream ports, offers plug-and-play functionality, and is cost-effective for mass production.

Package
The FE1.1 is a USB hub controller IC, commonly available in SSOP-28 (Shrink Small Outline Package, 28 pins) or QFN-32 (Quad Flat No-leads, 32 pins) packages. These compact packages are designed for space-efficient PCB layouts, suitable for USB 2.0 applications. The SSOP-28 is more traditional, while QFN-32 offers better thermal performance and smaller footprint.
