Memory with the SMD marking 24M02FU

[yarda]

Hi, I ordered on rs-online memory M24M02E-UFMN6TP. The memory that I received has SMD marking 24M02FU (photo: https://ibb.co/gLCbX0vb). I was unable to lookup this marking on the st.com web nor in the M24M02E datasheet. The rs-online vendor also don’t know :). Can anybody verify that it’s the M24M02E, i.e. memory with the following datasheet: https://www.st.com/resource/en/datasheet/m24m02e-u.pdf ? I need 2 MBit, up to 5 ms write. IMHO the suffix 'E' distinguishes the 5 ms memories from the 10 ms and I need to be sure it’s the 5 ms version of the memory. Thanks.

Welcome ​@yarda, to the community!

The marking 24M02FU stands for M24M02E-UFMN6TP, which offers a 5 ms write time.
The older alternative M24M02-DRMN6TP, now marked NRND (Not Recommended for New Design), has a 10 ms write time and the marking 24M02RD.

Since the last letter of the marking of your devices can be recognised quite clearly as a U, you can be quite reassured.

Hope that answers your question?
