AN2720SC Overview
Key Features
- In a USB system, the PC acts as a host, which initiates all USB traffic
- USB devices act as slaves, which respond to host requests
- It is inherently incompatible to connect two PCs together via a simple USB cable, since a master (host) cannot talk to another master (host)
- A master can talk only to one or more slave devices
- The AN2720SC overcomes this “peer-to-peer” incompatibility by providing two USB devices, one for each PC
- Two independent Serial Interface Engines (SIE) exchange data through a 2 kilobyte FIFO
- Thus, USB data transmitted by one computer is made available to the other computer through the AN2720SC
- The connection is full duplex– data can be transferred in both directions simultaneously
- AN2720SC EZ-Link (AN2720SC)
