SAB 80C166/83C166
Functional Description
The architecture of the SAB 80C166 combines advantages of both RISC and CISC processors and
of advanced peripheral subsystems in a very well-balanced way. The following block diagram gives
an overview of the different on-chip components and of the advanced, high bandwidth internal bus
structure of the SAB 80C166.
Note: All time specifications refer to a CPU clock of 20 MHz
(see definition in the AC Characteristics section).
