At the time this is written (May 2008), the M25P10-AVMN6TP model is easily available. But whatever the name, the important parts of it here are:
- M25P: the model
- 10 (or more than 10, but this useless for our purpose): the 128 KB size (the particular 05 models above are an exception to the norm, since most 05 models are the true 64 KB variety)
- MN: SO8 type of packaging.

64K chips bear the labels:

* M25P05AV (second line ending in "B")
* M25P05 (any other suffix not listed above)
