Foreword by Brian Booker


We were pleased to get John Hyde to write this book on
Cypress Semiconductor’s behalf. It should be considered a
supplement to his “USB Design By Example” in the same
way that the OTG plements the USB
Specification. Only the new elements of multi-role device
design are covered since these build on the established
base defined by the USB specification.
Cypress Semiconductor supports all facets of USB
design and has products covering the breadth and depth of
possible USB solutions. The two products described in this
book, the CY7C67200 EZ-OTG Host/Peripheral Controller
and the CY7C67300 EZ-Host Host/Peripheral Controller will
enable new designs particularly in the portable applications
arena. This book, with the support of other Cypress
documentation, should get your USB product idea rapidly
into development and then into the prototype stages. We at
Cypress Semiconductor are dedicated to supporting your
design efforts through production and 24 hour support is
available at .

Acknowledgements:

I would like to thank Cypress Semiconductor for providing
me with an opportunity to write about these two remarkable
components. The EZ-Host and EZ-OTG include features
that enabled me to solve a much wider range of customer
projects. I particularly like the small size of the EZ-OTG
since it enables USB to be used in many more solutions.

I could not pleted this book without the expert help
of Cypress’s Systems Engineering Team in Boise. I mu
