I know an IC's from Philips (look at theri homepage) which measures the
temperature directly (without any external sensors) and could be accesed
over a IÓC interface. For storing this data you could user IÓC
controllable EEProms. If your PIC doesn't have to do anythins except
measuring temeperature and storing the values you could use one of the
8-pin PIC (i.e. 12C508) cause you need just 2 pins for IÓC communication.
Downloading could also be done over IÓC or over a serial link to a pc
