Let's estimate some figures:

In the datasheet you'll find a maximum supply current of 2mA @ 5.5V and 1MHz = 11mW.

This power would lead to a temperature difference of 2.2K if we assume a (really, really bad) value of 200K/W.

Reading the whole content of a 2Mbit EEPROM at 1MHz would take about 3s or so, after that it typically goes to standby with max 40µA = 220µW, which then generates a negligible increase in temperature.

The absolute maximum ambient temperature according to the data sheet, table 5, is 130°C, and according to the operating specification (data sheet, table 7) it is 125°C. Since the maximum temperature difference is in or even below the single-digit range, the junction temperature can be equated to the ambient temperature.

Have you got any good reason that someone provides the exact thermal resistance of such an EEPROM?

Kind regards,

/Peter

Hi,

added to what @Peter BENSCH wrote, 

just to give a number for a so-8 case :
