cycle operation to keep timing compatible with original 8051 systems. However, they can be programmed
to run at the new 4 clocks per cycle if desired.
New hardware features are accessed using Special Function Registers that do not overlap with standard
80C32 locations. A summary of these SFRs is provided below.
The DS80C320/DS80C323 addresses memory in an identical fashion to the standard 80C32. Electrical
timing will appear different due to the high-speed nature of the product. However, the signals are
essentially the same. Detailed timing diagrams are provided below in the electrical specifications.
This data sheet assumes the user is familiar with the basic features of the standard 80C32. In addition to
these standard features, the DS80C320/DS80C323 includes many new functions. This data sheet provides
only a summary and overview. Detailed descriptions are available in the User’s Guide located in the front
of the High-Speed Microcontroller data book.
