5x86 Notes:

• Maximum power dissipation was calculated from P_max=(T_case-T_ambient)/(O_ja-O_jc). Where O_ja (theta) is junction-to-ambient thermal resistance and O_jc is junction-to-case thermal resistance in °C/W. T_ambient was measured at 3.3V and 0.931A.

i486 Notes:

• The 486 processor power numbers come from the embedded processor notes, and not from the original datasheets. The actual numbers for the chips sold in the retail market may vary slightly, but not by very much.
• Typical power dissipation was average value measured at typical voltage running typical applications, but is highly dependent on specific system configuration.
• Maximum active power dissipation is measured at typical voltages and worst-case instruction mix.
• The 486DX has a floating point unit (FPU) while the 486SX does not. Some of the earliest 486SX were 486DX chips with their FPUs disabled, but most were manufactured without the FPU.
• All surface-mounted (QFP) Intel 486 chips run at 3.3 volts. All socketed (168-pin PGA) Intel 486 chips run at 5 volts (except for the i486DX4 chips).

SGS 486 Notes:

• The Absolute Maximum Voltages are the highest voltages the chips can take for a short period of time. Extended use of the processor at or near these voltages will cause permanent damage to the chip. Reliable operation of the chip outside its nominal voltage range is not guaranteed.
• Maximum power dissipation was calculated from P=Vcc*Icc.
