Hi Valery,
I think i know where it went wrong.
It's mentioned in the datasheet that page 7 (0xF8A0-0xF8FF) of the EEPROM is reserved. Any attempt to read or write that part will result NACK on the i2c bus.
so you don't need to write to that part of the EEPROM and can ignore it during content verification.
For 0xFA00-0xFBFF, that's where the sequencing engine data is stored and you need to stop the sequencing engine before you can read/write to it. Detail instruction is here:

all related documentations can be found here, which may help.
i also attached a file that explains the EEPROM content of the device.
now you've mentioned
"comparing the .hex file with the EEPROM configuration using the Super Sequencer evaluation software"
may i ask which software did you use for this? the main GUI or prog106x.exe?
the main GUI doesn't allow you to compare content to hex file, it only do txt files.
the prog106x.exe could do this.
I will need more details on this to answer it.
anyway, try the above method and see if you can get it working.
