35080 is not typical eeprom and has different connections, please note at wiring diagram in application and important notes:

pin 1 to pin 2
pin 2 to pin 4 etc.

Please note!
- incremental register (0x00-0x1F) may be written only with higher value,
- device has different connections (please use adapter or soic clip)

Incremental register:
- first 32 bytes (0x00 - 0x1F),
- default values for incremental register are 0x00 (for blank memory),
- there is no possibility to erase incremental register*
* it is possible only to write higher value, e.g. 0x01 in place of 0x00 will work

Based on datasheet, incremental register can not be erased. In practice it is protected
(crypto) area. There are some devices on market (35080 eraser) which will erase some
of these devices.


95160 will work in built-in adapter - just put eeprom in soic socket, select EEPROM -> 95 series -> 95160 and it has to work.
