AMD Athlon™ XP Processor Model 10 Data Sheet

8 Electrical Data

This chapter describes the electrical characteristics that apply to all desktop AMD Athlon™ XP processors model 10.

8.1Conventions

The conventions used in this chapter are as follows:

■Current specified as being sourced by the processor is negative.

■Current specified as being sunk by the processor is positive.

8.2Interface Signal Groupings

The electrical data in this chapter is presented separately for each signal group.

Table 9 defines each group and the signals contained in each group.
