The st,m95640 is a 64 Kbit SPI eeprom in the same family as the two
existing st,m95* compatibles.

In case its relevant the data sheet is easily available from
https://www.st.com/en/memories/m95640-w.html . It seems odd they chose
right-pad with a 0, 640 instead of 064 (m02 means 2 Mbit, 256 means
256 Kbit, so there's some logic to that), but here we are.
