Note: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. During absolute maximum rating overload conditions (VIN > VDD or VIN < VSS) the voltage on VDD pins with respect to ground (VSS) must not exceed the values defined by the absolute maximum ratings.


Description

The architecture of the C161K/O 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 C161K/O.
