We wish to use the 28-pin version of the CY7C65632 4-port hub controller, but three of the four downstream devices will be non-removable. The 28-pin package doesn't allow us to strap ports as non-removable. Will this cause a problem? For instance, will the hub fail to see the downstream devices because there won't be the transition from disconnected to connected in order to trigger the hub to enumerate the downstream devices?
Thanks,
Scott

Hello Scott,
You can not use 28 pin package for non removable application using pin strapping. But you can use EEPROM and boot using EEPROM. Please refer to the page 15 of datasheet. Please refer to the link below for the datasheet..

Hi Krishna,
We would prefer not to use the EEPROM. What problem will happen if we use the 28-pin part with non-removeable downstream devices?
Thanks,
Scott
