CY7C65640 and blank 25LC040
In my design I have CY7C65640-LTXC and EEPROM 25LC040-ISN. Is it a MUST to load EEPROM with at least default configuration 0xD0 Load, or will the USB hub run correctly when EEPROM blank? How would I go on about programming this EEPROM?
On power up sometimes (1 in 15 time) CY7C65640-LTXC is stuck and the hub is not operating properly (it does not recover after chip reset, only on power up), could this be because EEPROM is blank?
