Hi,
For my project, I am using an M24M01E-F I2C EEPROM. My application requires writing and reading data page-wise. According to the datasheet, the EEPROM has a capacity of 1 Mbit (128 KB). I need clarification on how many pages I can able write to using this EEPROM."
To clarify, the M24M01E-F EEPROM has a total of 512 pages, with each page being 256 bytes
Solved! Go to Solution.

All 512 pages are of course accessible, access to the pages should only be limited by the MCU used and its programme.

Welcome @Rishvana, to the community!
Correct, M24M01E contains 128KB EEPROM, which are divided into 512 pages with 256 bytes each.
Does it answer your question?

Thank you, @Peter BENSCH,
Am I able to access all 512 pages?
Is there a page limitation when writing and reading?
because,
In my application, I am currently able to write only 416 pages in one write and read cycle. During the subsequent write cycle, a communication error occurs in both I2C read and write operations. I am using I2C communication with a clock frequency of 100 kHz.
Can you clarify this for me? Your help would be greatly appreciated.

Yes, you can use the identification page for your purposes, but it can only be set to read-only and may therefore not be suitable for confidential information.
The procedure for accessing this identification page is described in the data sheet, section 4.4.

Hi Peter,
Could you please provide sample code for accessing the identification page and the locking mechanism?
Thanks,
Rishvana
