Your search - ST25p64 - did not match any documents.
not a stock item in google.

is the number correct?

Maybe the M25P64 from ST ?

Yes, http://www.st.com/stonline/books/ascii/docs/10987.htm

I'll go have a read, thanks

Look here

http://www.engelmann-schrader.de/usbstick.html (in german but manual in english)

This is not only a Usb Stick but also a kind of " Serial Stick".

You might want to consider the AT45DBxxx series of dataflash.
This has an SPI interface and SMALL sectors (up to 1 kB).
The advantage of small sectors is that file system typically do not need
garbage collection (or it is simplified).
The pages have "extra bytes" allowing erase count and other things useable
in a flash file system.
The devices start at 1 Mbit and go up to 64 Mbit in pin compatible 8 pin
packages.
Larger memories are in development.

You can also get 16/34/64 Mbit in MMC like Flash card packages,
so add an MMC connector to your board and you are in good shape.
