Functional Description
The architecture of the C161S combines advantages of both RISC and CISC processors
and of advanced peripheral subsystems in a very well-balanced way. In addition the on-
chip memory blocks allow the design of compact systems with maximum performance.
Figure 3 gives an overview of the different on-chip components and of the advanced,
high bandwidth internal bus structure of the C161S.
Note: All time specifications refer to a CPU clock of 20 MHz
(see definition in the AC Characteristics section).

Block Diagram
The program memory, the internal RAM (IRAM) and the set of generic peripherals are
connected to the CPU via separate buses. A fourth bus, the XBUS, connects external
resources as well as additional on-chip resources, the X-Peripherals (see Figure 3).
