SA-110 Microprocessor (SA-110), the first member of the
StrongARM family, the SA-1100 provides power efficiency, low cost, and high performance.
Figure 1-1 shows the features of the SA-1100. The shaded boxes are features that have carried over
with few or no changes from the SA-110. The nonshaded boxes are new or updated features for the
