Hi there !

I hope someone can help me with a confusion i had in my mind right now. I work with a EEPROM 24C256 and need a write a lot of data inside , soo i decide to use the page write solution . So from the datasheet i saw i can write 64byte in one shot.

and here i have a doubt. if i start from the address 0x00 i know i can write until 0x3F.But if i start to write from 0x10 i can write until 0x3F right of course not 64Byte but 48Bytes is it right ? 

 

Thank you 

Sergio

The above seems pretty clear on what happens if you try to write beyond the end of the page?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
