General

The CY4601 reference design is a single code base that supports both the CY7C63743 and the CY7C64013 parts. The firmware for these parts will only support upto 57.6K baud. This is a limitation of the firmware and not the Virtual COM port driver. The Virtual COM port driver itself supports 115.2K baud.

Included in the reference design is some untested sample code for our EZ-USB AN2131 part. It is possible to support 115.2K baud using this part with an external crystal. This design will require further development and testing on the customers part. It is only supplied as sample code which has not been fully tested or finished. It is not officially part of the reference.

The maximum value Drive Strength is set by default to 01 (Medium Low) for a 3.3V and 10 for 2.5V (Medium High). This crosses into a minimum 15 mA and a maximum of 23 mA. These should correspond to the ranges obtained by the High and Low drive strength settings.

NX2LP does not support MLC Flash Devices. The NX2LP has 1-bit ECC correction per 256-byte, which will not be able to handle MLC NAND. The MLC NAND requires 4-bit ECC correction.

After installing the development tools. The JEDEC files can be found at the location Cypress\USB\Hardware\EZ-USBSeries2100\PALEquations.

There is no direct replacement available for CY7C63613-SC. The function replacement is EncoreII devices. More information can be found on this link.

The latest version of the framework has a compile option for supporting Remote Wake up. Please go through the example.

One easy way is to load it into the Hi-Lo buffer. There's a "Buffer Checksum" feature on the Cystart Hi-Lo software.

USBSTOR.sys supports the ISD-200 and this driver comes along with the Windows XP OS. 

The CY3671 EZ-USB FX development board will work with Windows 98SE, Windows ME, Windows 2000 and Windows XP.  Booting up under Windows ME and re-installing the development kit CD should solve this problem.

The CY64x13 hardware automatically generates SE0s. This feature was implemented specifically as a means of preventing babble in hub applications. For the most part, this behavior has been successfully implemented with no ill effects. However, in some host environments and in non-hub applications this might cause some problems. The register located at F2h is an undocumented register. Writing a 10h to register F2h disables the generation of SE0s.
