FE1.1s — USB 2.0 4-Port STT Hub Controller

FE1.1s is a highly integrated, high-quality, and high-performance solution for USB 2.0 High Speed 4-Port Hub. With tiny footprint and extremely low power consumption, it is the best choice for embedded system and standalone hub.

Battery Charging Configuration

FE1.1s could be optionally configured to support Charging Downstream Ports as defined by USB-IF Battery Charging Specification Revision 1.1/1.2. When enabling this feature, a USB hub could be transformed into a charging station for Universal Charging Solution-compliant battery-based portable devices.

Customizable EEPROM

FE1.1s allows EEPROM configuration for customizing Vendor ID, Product ID, Device Release Number, and the number of downstream ports.

Quality Guaranteed

Quality is guaranteed by Design-For-Testing with comprehensive scan chains and Built-In-Self-Test modes which could exercise all high-, full-, and low-speed Analog Front End (AFE) components at the packaging and testing stages.
