TERMINUS FE2.1
The FE2.1 is a highly integrated, high quality, high performance, low power consumption, yet low overall cost solution for USB 2.0 High Speed 7-Port Hub. It adopts Multiple Transaction Translator (MTT) architecture to explore the maximum possible throughput. The whole design is based on state-machine-control to reduce the response delay time; no micro controller is used in this chip.FEATURES
