Unable to Identify Pin-1 Orientation on M95P08-IXMNT/E – No Visible Marking on Package

[Ushasri]

Hi,

I am using the M95P08-IXMNT/E flash memory IC and I am unable to identify the Pin-1 orientation on the package.

The device does not appear to have any visible:

• dot/dimple
• chamfer
• laser marking
• beveled corner

I checked carefully under light and magnification, but I still cannot find any Pin-1 indication.

Could anyone please help with:

1. How to identify Pin-1 on this package?
2. Any package photos/reference images?
3. Whether some lots come without visible Pin-1 markings?

Thanks.

The edge starting with pin 1 is a bit different, see picture.

The SO-8 package should have a chamfer on the Pin-1 side.

Can you share a clear picture?
