... Compatible with Industry Standard 8051 Instruction Set and Pinout Optional Permanently Powered Real-Time Clock (DS5000T) 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 V program/data memory space is implemented using either kbytes of nonvolatile CMOS SRAM ...

... DS5000(T) CPU. The 8- or 32-kbyte RAM area inside of the DS5000(T) can be used to contain both program and data memory. The real-time clock (RTC) in the DS5000T is reached in the memory map by setting a SFR bit. The MCON.2 bit (ECE2) is used to select an alternate data memory map. While ECE2 = 1, all MOVXs will be routed to this alternate memory map. The RTC is a serial device that resides in this area. A full description of the RTC access and example software is given in the Secure Microcontroller User’ ...

... Serial Program Loading that can perform Bootstrap Loading of the DS5000(T). This feature allows the loading of the application program to be delayed until the DS5000(T) is installed in the end system. Dallas Semiconductor strongly recommends the use of serial program loading because of its versatility and ease of use. ...
