HS8845A    HS8845B  
USB高速2.0 hub 一拖四口 输入5v 输出3.3v

1.0 Description
Compliant to USB specifcation Revision 2.0
Suppout 4/3/2 downstream ports by I/O pin configuration
Upstream port supports both high-speed (HS) and fulkspced (S) trafhc
Downsiream ports support HS, FS, and low-speed ( S) traffic
On-chip 8.bit micro-processorRISC.like architectureUSB optimized instruction set
Single Transaction Translator(STT)Single 'T'T shares the same 'T'T control logics for all downstream port devices. This is the most costellective solution for T'T, Mulliple 'T'T provides individual 'T'T eontrol logics for each downstream portThis is a performance better choice for UiSB 2.0 hub
Integrate USB 2.0 transcciver
Each downstream port supports two-color status indicator, with automatic and manual modes compliant toUSB specifcation Revision 2.0
Embed serial resister for USB signalsSupport both individual and gang modes of power management and over-current detection fordownstream poris
Conform to bus power requirements
Automatic switching between self-powered and bus-powered modes
Support compound-device (non-emovable in downstream ports) by I/O pin conligurationConfigurable non.removable device support
Embeds $V to 3.3V regulator
Improve output drivers with slewrate control for EMI reduction
Internal powei-fail deteetion for ESD recovery
