AN69235 - MIGRATING FROM HX2/HX2LP TO HX2VL | Cypress Semiconductor


Last Updated: 
Mar 02, 2021
AN69235 is intended to help the developer migrate a hub design based on EZ-USB® HX2™ (CY7C65640A)/ EZ-USB® HX2LP™ (CY7C65630/20) to use the HX2VL™ (CY7C65642/32/34) hub. It also provides a feature comparison between HX2, HX2LP, and HX2VL to aid in the selection of the appropriate part number for migration. One must note that HX2 (TetraHub) is now not recommended for new designs.
