What external EEPROM is recommended for use with the FTDI USB Hi-Speed ICs?

For the FT2232H and FT4232H, a 93C46, 93C56 or 93C66 is recommended. The FT232H requires the 93C56 or 93C66. All of these serial EEPROMs need to be specified or configured for 16-bit word and 3.3V I/O operation. There are many manufacturers of this type of device, and FTDI does not have a preference.
