Want to know the memory roll over scenario in case of byte write in EEPROM M95M02-A125..

[ANair.10]

The EEPROM range for M95M02-A125 is from 0x00 to 0x3ffff. When a byte write is initiated at 0x40000, it overwrites the contents of the location 0x00. Is this the expected behavior? In data sheet the roll over for page write is mentioned, like the internal address pointer will roll back to starting address of that particular page(1 page=256 bytes), but nothing on byte write roll over ... i would like to know byte write case...

If it is not described in the spec, it is not guaranteed. Are you trying to autodetect the memory size?

​hello,

the device catches only A17 & A16 of the 3rd byte of address. A18 is not read.

Thanks for thinking ST.
