DESCRIPTION  
The DS5000(T) Soft Microcontroller Module is a fully 8051-compatible 8-bit CMOS microcontroller that  
offers “softness” in all aspects of its application. This is accomplished through the comprehensive use of  
nonvolatile technology to preserve all information in the absence of system VCC. The internal  
program/data memory space is implemented using either 8 or 32 kbytes 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 onboard crystal.  
Note: Some revisions of this device may incorporate deviations from published specifications known  
as errata. Multiple revisions of any device may be simultaneously available through various sales  
channels. For information about device errata, click here: http://dbserv.maxim-ic.com/errata.cfm.
