Notes:
1. These values apply for all valid 60x buses. The values do not include I/O Supply Power (OV ) or PLL/DLL supply power (AV ). OV
DD DD DD
power is sys-
tem dependent, but is typically <2% of V
power. AV
DD
current is less than 25mA each for AV
and AV

2. Maximum power is specified for fastest (worst process) parts running RC5 at the indicated core voltage, junction temperature, and core frequency.
3. Typical power is specified for median process 800 MHz parts0 running RC5 at the indicated core voltage, junction temperature, and core frequency.
The value is then adjusted for 13% less switching (AC component for PD) to account for the differences between RC5 and more typical application
code.
Previous revisions of this datasheet showed incorrectly low power dissipation values. The power dissipation
of the 750FX has not increased, the datasheet has only been corrected to show the actual values.
