AT43301中文资料Low-cost USB Hub Controller数据手册Microchip规格书

描述 Description

The AT43301 is a 5-port USB hub chip supporting one upstream and four down stream ports. The AT43301 connects to an upstream hub or host/root hub via Port0, while the other ports connect to external downstream USB devices. The hub re-trans mits the USB differential signal between Port0 and Ports[1:4] in both directions. The AT43301 is designed for very low-cost bus-powered or self-powered hub applications
and is available in a 24-lead SOIC and a 32-lead LQFP packages. The 32-lead version of the AT43301, the AT43301-AC, has a 48 MHz clock input.
