DESCRIPTION  
The DS5000(T) Soft Microcontroller Module is a fully  
8051compatible8–bitCMOSmicrocontrollerthatoffers  
“softness” in all aspects of its application. This is ac-  
complishedthroughthecomprehensiveuseofnonvola-  
tile technology to preserve all information in the ab-  
32K bytes of nonvolatile CMOS SRAM. Furthermore,  
internal data registers and key configuration registers  
are also nonvolatile. An optional real time clock gives  
permanently powered timekeeping. The clock keeps  
time to a hundredth of a second using an on–board  
crystal.

The internal program/data

memory space is implemented using either 8K or
