Notes:
1. These values apply for all valid 60× buses. The values do not include I/O supply power (OVDD) or PLL supply power (AVDD). OVDD
power is system dependent, but is typically less than 2% of VDD power.
2. Maximum power is measured at the indicated VDD and TJ using parts with worst-case process parameters and running RC5-72.
RC5-72 runs hotter than typical production code, but it is possible to design code that runs even hotter than RC5-72. See Reduc-
ing PowerPC 750GX Power Dissipation Application Note for more information.
3. Typical power is an estimate of the average value modeled in a system executing typical applications with VDD and typical process
parameters. Note that typical power cannot be used in the design of the power supply or cooling system.
4. Timing and all AC/DC characteristics are guaranteed over the Vdd range of 1.20v to 1.55v. The supported Vdd operating range for
800MHz and 933MHz operation are as shown. Power is specified at the single Core (Vdd) voltage shown, not over the Recom-
mended Operating Conditions range. For example, the maximum power at 800MHz/105C/1.45v is 8.5W. Maximum power at
higher voltage or frequency will be higher.
