EZ-Link (AN2720SC)

Single-Chip USB-to-USB Networking Solution

FEATURES

• Smallest completely integrated solution in the market

• 32 pin TQFP

• Only requires a single crystal and small 16 byte serial EEPROM for full implementation

• Meets difficult suspend current of 500 uA for both hosts

• 2K data buffer for maximum speed transfer

• Greater than 5 Mbps data transfer rate

• Low power – Less than 100 mW power

OVERVIEW

The Cypress AN2720SC provides a single-chip solution for networking two or more computers

via their USB ports. 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.
