CY7C65642 28QFPN package. Without eeprom how port selection will happen

Anonymous · ‎Jun 30, 2018

Hi,

I need to understand with CY7C65642 28QFPN if i want to avoid using EEPROM, how system will behave. What is the default values it take. As per flow chart its mentioned default value, but did not get what it is. Will device route the data between host and device?

Thank you,

Hello Arun KS,

By default, the hub has got its configurations in an internal ROM. An EEPROM can optionally be added externally in case there is a need to modify certain parameters such as VID/PID, number of removable ports, etc. The hub IC has got its entire firmware in itself and hence the data routing between host and device occurs without the presence of EEPROM too.

Best regards,

Srinath S
