M24512E-FMN6TP addressing

[GorEks]

Hi,

trying to get an M24512E-FMN6TP running but I only receive I2C NACKs using the default address in the DS13657 - Rev 3 - October 2023 data sheet. After some detailed reading it seems the FMN6TP device does not apply to this data sheet, there is a cryptic note under 11 Ordering information saying I should use the data sheet M24512E-F revision 1 - October 07,2022 which I cannot find, either on the ST web site or via Google.

What is up with this device and where can I find the correct data sheet?

 

Thanks

Goran

Welcome @GorEks, to the community!

You probably don't need this old data sheet, because the footnote you mentioned refers to markings 24512FP and KxxxV.

However, the last point of table 24 above the footnote still reads

Plating technology and device address
P or G = ECOPACK2 and device address 000

Does it answer your question?

Regards

Aaah, that simple! Why couldn't you have added that to Table 6 in the DS instead of hiding it under Ordering information?

For anyone reading this, it means the Chip enable address bits C0-2 are 0 in the DS table 6 and 9 for the FMN6TP device.
