31994A —1 August 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.
7.1 Conventions
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.
7.2 Interface 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.
