HS8845A USB 2.0HUB Controller for Datasheet

0 Description
Compliant to USB specification Revision 2.0
-Support 4/3/2 downstream ports by I/O pin configuration
- Upstream port supports both high-speed (HS) and full-speed(FS) traffic
- Downstream ports support HS, FS, and low-speed (LS) traffic
On-chip8-bit micro-processor
-RISC-like architecture
-USB optimized instruction set
Single Transaction Translator (STT)
- Single TT shares the same TT control logics for all downstream port devices. This is the most cost
effective solution for TT. Multiple TTprovides individual TT control logics for each downstream port.
