2.9 Maximum Ratings
Table 5 lists the processor’s maximum environmental stress ratings. Functional operation at the
absolute maximum and minimum is neither implied nor guaranteed. The processor should not
receive a clock while subjected to these conditions. Functional operating parameters are listed in
the AC and DC tables. Extended exposure to the maximum ratings may affect device reliability.
Furthermore, although the processor contains protective circuitry to resist damage from electro
static discharge (ESD), one should always take precautions to avoid high static voltages or electric
fields.
NOTE:
1. This rating applies to any processor pin.
2. Contact Intel for storage requirements in excess of one year.
2.10 Processor DC Specifications
The processor DC specifications in this section are defined at the processor core silicon and
not at the package pins unless noted otherwise. See Chapter 5.0 for the pin signal definitions and
signal pin assignments. Most of the signals on the processor system bus are in the AGTL+ signal
group. The DC specifications for these signals are listed in Table 9.
Previously, legacy signals and Test Access Port (TAP) signals to the processor used low-voltage
CMOS buffer types. However, these interfaces now follow DC specifications similar to GTL+. The
DC specifications for these signal groups are listed in Table 10.
Table 6 through Table 11 list the DC specifications for the Celeron
processor in the 478-pin
package and are valid only while meeting specifications for case temperature, clock frequency, and
input voltages. Care should be taken to read all notes associated with each parameter.
