• Manufacturer: Infineon Technologies Corporation

Functional Description
The architecture of the C161CS/JC/JI 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 C161CS/JC/JI.
Note: All time specifications refer to a CPU clock of 25 MHz
Figure 3
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 resoures, the X-Peripherals (see
The XBUS resources (XRAM, CAN, SDLM, IIC, ASC1) of the C161CS/JC/JI can be
enabled during initialization by setting the general X-Peripheral enable bit XPEN
(SYSCON.2).
If the X-Peripherals remain disabled they consume neither address space nor port pins.
