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.
USB-IF 充電架構
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.
客製化 EEPROM
FE1.1s allows EEPROM configuration for customizing Vendor ID, Product ID, Device Release Number, and the number of downstream ports.
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.
