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.
