AC Parameters

This chapter defines the ac parameters for the Intel
®
StrongARM
®
SA-1100 Microprocessor
(SA-1100).
13.1 Test Conditions
The AC timing diagrams presented in this chapter assume that the outputs of SA-1100 have been
loaded with a 50-pF capacitive load on output signals. The output pads of SA-1100 are CMOS
drivers that exhibit a propagation delay that increases with the increase in load capacitance.
Table 13-1 lists the output derating figure for each output pad, showing the approximate rate of
increase of delay with increasing or decreasing load capacitance for a typical process at room
temperature. For derating figures for 2.0-V devices, contact the Intel Massachusetts Customer
Technology Center.
