Inconsistent internal structure and marking for the same part number.Part number: M24C64-WDW6TP

[EJian.2]

I encountered a problem with inconsistent internal structure and marking for the same part number.We only found a document with such a problem.But it isn't suitable for this time.The document was published in 2014. It only mentions "T" and "K". But we need to explain "T" and "P".The detail as attachment. If they are the same in function?PCN MMS-MMY/14/8508 - Dated 16 Jul 2014

Hi,

464WT is a M24C64 range W in TSSOP8 manufactured in CMOSF8H+.

464WP is an old M24C64 range W in TSSOP8 manufactured in CMOSF6 26%. This can be crosschecked with the information "M24C64-WDW6TPPTB " written on the box label marking.

The product manufactured in CMOSF6 26% is obsolete since many years now.

See attached pcn 5902

Best Regards

You mean the part with marking 464WP is OBSOLETE which means This product is no longer in production?Could you help me to confirm the Bulk ID T0O424HV0020。Could you help me to find the shipped date of it?

We could only find the DC is 042 from the label and marking.But we couldn't know it means year 2010 or 2020?

Hi,

After investigations, your bulk ID is correct and corresponds to ST standard.

I confirm also it's 2010.
