It's hard to read what is written on this dataflash memory but it looks like 25p80vg. I searched for datasheets and found some things similar to it, but couldn't find anything that matched it exactly. Are there datasheets for this?
the data sheet i used to answer your other question is http://pdf1.alldatasheet.com/datasheet-pdf/view/181475/WINBOND/W25P80VFIG.html
The last to letters (VG) are voltages And packaging information
