Absolute Maximum and Minimum Ratings
specifies absolute maximum and minimum ratings. Within functional operation limits,
functionality and long-term reliability can be expected.
At conditions outside functional operation condition limits, but within absolute maximum and
minimum ratings, neither functionality nor long-term reliability can be expected. If a device is
returned to conditions within functional operation limits after having been subjected to conditions
outside these limits, but within the absolute maximum and minimum ratings, the device may be
functional, but with its lifetime degraded depending on exposure to conditions exceeding the
functional operation condition limits.

returned to conditions within functional operation limits after having been subjected to conditions
outside these limits, but within the absolute maximum and minimum ratings, the device may be
functional, but with its lifetime degraded depending on exposure to conditions exceeding the
functional operation condition limits.
At conditions exceeding absolute maximum and minimum ratings, neither functionality nor long-
term reliability can be expected. Moreover, if a device is subjected to these conditions for any
length of time then, when returned to conditions within the functional operating condition limits, it
will either not function, or its reliability will be severely degraded.

Although the processor contains protective circuitry to resist damage from static electric discharge,
precautions should always be taken to avoid high static voltages or electric fields.

Processor DC Specifications
The processor DC specifications in this section are defined at the processor core silicon and
not at the package lands unless noted otherwise. See

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

NOTES:
1.
For functional operation, all processor electrical, signal quality, mechanical and thermal specifications must be satisfied.
2.
Excessive overshoot or undershoot on any signal will likely result in permanent damage to the processor.

Storage temperature is applicable to storage conditions only. In this scenario, the processor must not receive a clock, and
no lands can be connected to a voltage bias. Storage within these limits will not affect the long-term reliability of the device.
For functional operation, refer to the processor case temperature specifications.
