Electrical Specifications

This section specifies the following electrical behavior of the 21555:

• PCI electrical conformance.

• Absolute maximum ratings.

• DC specifications.

• AC timing specifications.

3.1

PCI Electrical Specification Conformance

The 21555 PCI pins conform to the basic set of PCI electrical specifications in the PCI Local Bus

Specification, Revision 2.2. See that document for a complete description of the PCI I/O protocol

and pin AC specifications.

3.2

Absolute Maximum Ratings

The 21555 is specified to operate at a maximum frequency of 33 MHz or 66 MHz if 66 MHz

capable, at a junction temperature (Tj) not to exceed 125°C. Table 5 lists the absolute maximum

ratings for the 21555. Stressing the device beyond the absolute maximum ratings may cause

permanent damage. These are stress ratings only. Operating beyond the functional operating range

is not recommended and extended exposure beyond the functional operating range may affect

reliability. Table 6 lists the functional operating range.
