Hello,
I am a automotive firmware developer.
I'm developing using the M24512-DRMN3TP/K product.
I have a question.
I have used the FM24CL16B (AT24/FM24) model before.
FM24CL16B model had 1010+page select in SLAVE ADDRESS.
I was able to fully understand the FM24CL16B product.
I can't figure out how to page select the M24512 product.
Please tell me how to select page.
And please tell me the number of pages.
Please tell me the byte size of 1 page.
I look forward to your reply.
Best Regards, Kim

Please do not confuse FRAM with EEPROM, which each have a slightly different structure. The EEPROM M24512-DRMN3TP/K also has a mode in which pages can be written, but the principle is somewhat different and is described in the datasheet under Section 4.1.2:
[...]The Page Write mode allows up to N bytes (N=(128) to be written in a single Write cycle, provided that they are all located in the same page in the memory: that is, the most significant memory address bits, A15/A7, are the same. [...]
The M24512-DRMN3TP/K contains 64 KBytes of EEPROM organized in 512 pages of 128 Bytes each and additionally an identification page with a size of 128 Bytes.
The identification page can be locked, which is permanent and cannot be revoked. In the unlocked state, the page can be used normally.
Regards
