Considerations for Porting Existing EZ-USB FX Firmware to EZ-USB FX1/FX2LP

Version 1
    Question: What are the consideration to be followed for porting existing EZ-USB FX firmware to EZ-USB FX1/FX2LP?



    Please read through application note Migrating from EZ-USB FX to FX1. This application note is intended for developers who are moving their existing CY7C64613 design to the new CY7C6471314 EZ-USB FX1(TM) device. FX1 is exactly similar to FX2LP with the only differing fact that the latter can support highspeed USB as well. Hence, this application note is also valid for developers who are looking to migrate to FX2LP from FX1.
