Correct. Q is a WSON package which does not fit at all. Make sure you
buy farnell nr. 1907085 and nothing else. A25L032-F is indeed the
accurate manufacturer's part number, if you order somewhere else.

Winbond W25Q64CV

But Winbond's distributors AVNET and Digi-Key,

http://www.winbond-usa.com/winbondcms/Application/member/Distributors.aspx?partno=W25Q64CV

only have SO-8 in stock, and you wanted DIP. You could look for
adapters, but then you must do some soldering.

AVNET only have SO-8 stock in Asia. You'll have to pay import fees
and tax. Digi-Keys f-ing website barfs some idiotic error at me
whenever I try to use it nowadays.


You can buy DIP from bios-repair.co.uk, but they only have the older
revision W25Q64BVAIG. For once they don't charge more than AVNET&co
in single quantity.

Click Winbond, then there's W25Q64BVAIG 64Mb PDIP top left in the
product listing.
