Question: What is the CY4640?
Answer: The CY4640 is the Mass Storage RDK for the EZ-Host IC. The CY4640 is easily configurable for the users needs and comes with hardware and firmware to get started very quickly. The CY4640 runs in stand-alone mode. The CY4640 uses a terminal emulator available on any PC as the user interface to the product. The CY4640 will enumerate up to two USB mass storage devices and also has the ability to talk to an internal IDE drive. The CY3663 on the other hand is a more full featured DVK used for non-mass storage developments. It includes the ability to develop in either co-processor or stand-alone mode. The CY4640 includes all of the development tools necessary to modify and rebuild the firmware to fit your needs.
