31994A —1August 2004 AMD Sempron™ Processor Model 10 with 256K L2 Cache Data Sheet

7 Electrical Data

This chapter describes the electrical characteristics that apply to all desktop AMD Sempron™ processors model 10 with 256K L2 cache.

7.1Conventions

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.

7.2Interface Signal Groupings

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

Table 5 defines each group and the signals contained in each group.
