Functional Description
The architecture of the C167CR 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.
The following block diagram gives an overview of the different on-chip components and
of the advanced, high bandwidth internal bus structure of the C167CR.
Note: All time specifications refer to a CPU clock of 33 MHz
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

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
