M24512-W

[pepito60]

Hi,

I need help to identify a 512 Kbit serial I²C bus EEPROM from the M24512 series.

I have two differents parts which appear identical, apart from one letter at the end of the reference : M24512-WG for the first one and M24512-WP for the second (photos attached).

Could some tell me what is the difference beetween the two parts ?

Thanks.

Hi @pepito60 , 

Please note I am not an expert of EEPROM @ST, but when looking at the datasheet Datasheet - M24512-W M24512-R M24512-DF - 512-Kbit serial I²C bus EEPROM (st.com), it comes to me that in chapter 10 ordering information, there is something which could explain the meaning of these extension digits P or G: The Plating Technology (which is identified either by P or G = ECOPACK 2 ). Indeed the exact diffrence between both is not described here, but my understanding would be the plating technology may be different between parts. 

For further details, I would suggest to post a dedicated request to ST support.

Dear @STOne-32 ,

Thanks a lot for the information. I didn't have in my database the PCN MMS-MMY/09/4680 with the addentum, just the original one . The one with the addentum clearly explain the last digit.

Merci encore @Tesla DeLorean et @STOne-32
