AN2720S 数据手册

EZ-Link (AN2720SC)

CHIP DETAILS

The AN2720 contains two slave interfaces that transfer data between through a 2-kilobyte FIFO.

It also contains two 5V to 3.3V regulators to supply power to the chip and to the USB pullup

resistor. Figure 2 of this document shows a functional block diagram of the AN2720. The

AN2720 contains:

! Two 5V to 3.3V regulators, which deliver clean, regulated power to the chip and to

the pullup resistor connected to the USB D+ line. These regulators are powered by the

USB 5V line.

! Two USB transceivers, one for each computer.

! Two USB cores, each consisting of a Serial Interface Engine (SIE) and an intelligent

machine that can respond to standard USB requests. These are the same enhanced SIE’s

used in Cypress’ line of EZ-USB products.

! A 2-Kilobyte FIFO which is used to buffer multiple packets between computers to

optimize data throughput.

! Control logic to manage transfer of USB data between the two SIEs.

! A single-crystal oscillator and PLL, shared by both SIE’s.

SOFTWARE SUPPORT

Software is provided in two different configurations: Ethernet drivers or Ethernet plus bridging

software.

The Ethernet drivers run on Windows 95/98/2000 and are miniport device driver software which

emulates a network interface connector. It manages the USB protocol and the PC-to-PC data

flow. The EZ-Link Ethernet device driver is written to the NDIS (Network Driver Interface

Specification) standard and provides a standard Windows interface to the resources of the

hardware. To the end user, EZ-Link appears and behaves like an Ethernet card even though no

physical network interface card is present. Thus, users can use standard Windows interface such

as Windows Explorer, Network Neighborhood and standard file sharing security features. With

this driver, users can use multiple EZ-Links to generate their own private mobile network, with

access to other peripheral devices such as printers appearing as network peripherals.

The Ethernet plus bridging drivers run on Windows 95/98/2000. In addition to the Ethernet

connection capability between multiple EZ-Links, users can connect to corporate LANs using

the PC that has both EZ-Link and a corporate Ethernet connection as a bridge device. With this

capability, users have complete access to corporate LAN resources.
