NOTES:
1. For functional operation, all processor electrical, signal quality, mechanical, and thermal specifications must
be satisfied.
2. Overshoot and undershoot voltage guidelines for input, output, and I/O signals are outlined in Section 3.
Excessive overshoot or undershoot on any signal will likely result in permanent damage to the processor.
3. Storage temperature is applicable to storage conditions only. In this scenario, the processor must not receive
a clock, and no pins can be connected to a voltage bias. Storage within these limits will not affect the long-
term reliability of the device. For functional operation, please refer to the processor case temperature
specifications.
4. This rating applies to the processor and does not include any packaging or trays.

Processor DC Specifications
The following notes apply:
• The processor DC specifications in this section are defined at the processor core silicon and
not at the package pins unless noted otherwise.
• The notes associated with each parameter are part of the specification for that parameter.
• Unless otherwise noted, all specifications in the tables apply to all frequencies and cache sizes.
• Unless otherwise noted, all the specifications in the tables are based on estimates and
simulations. These specifications will be updated with characterized data from silicon
measurements at a later date.
See Section 6 for the pin signal definitions. Most of the signals on the processor front side bus are
in the AGTL+ signal group. The DC specifications for these signals are listed in Table 2-15.
Table 2-9 through Table 2-18 list the DC specifications for the processor and are valid only while
meeting specifications for case temperature, clock frequency, and input voltages.
Flexible Motherboard (FMB) Guidelines
The FMB guidelines are estimates of the maximum values that the processor will have over certain
time periods. The values are only estimates as actual specifications for future processors may
differ. The processor may or may not have specifications equal to the FMB value in the foreseeable
future. System designers should meet the FMB values to ensure that their systems will be
compatible with future releases of the processor.
