DC Characteristics

Table 9-10 describes the signal buffer types of the

SC3200. (See Table 3-2 "432-EBGA Ball Assignment -

Sorted by Ball Number" on page 29 and Table 3-4 "481-

TEPBGA Ball Assignment - Sorted by Ball Number" on

page 43) for each signal’s buffer type.)

The subsections that follows provide detailed DC charac-

teristics according to buffer type.
