All thermal impedance data is approximate for static
air conditions at 1W of power dissipation. Values will
change depending on operating conditions and ap-
plications. See the Intel Packaging Handbook (Order
No. 240800) for a description of Intel’s thermal im-
pedance test methodology.

DATA SHEET REVISION HISTORY
Data sheets are changed as new device information becomes available. Verify with your local Intel sales office
that you have the latest version before finalizing a design or ordering devices.
The following differences exist between this datasheet (272322-003) and the previous version (272322-002):
1. Removed 8XC51FX-3 and 8XC51FX-20, replaced with 8XC51FX-24.
2. Included 8XC51FX-24 and 8XC51FX-33 devices.
3. 80C51FA and 83C51FA now have the same features as 87C51FA, 8XC51FB and 8XC51FC; same DC spec
used for all devices.
The following differences exist between the ‘‘-002’’ and ‘‘-001’’ version of 8XC51FX datasheet:
1. Removed 8XC51FX-L from datasheet.
2. Include V
for 83C51FA (Express)/80C51FA (Express).
