DS5001FP 2 of 26 DESCRIPTION The DS5001FP 128k soft microprocessor chip is an 8051-compatible microp ro cessor based on NV RAM technology and designed for s ystems that need la rge quantities of nonvolatile memory. It provides full compatibility with the 8051 instructi on set, timers, serial port, and pa rallel I/O ports.

DS5001FP 6 of 26 INSTRUCTION SET The DS5001FP executes an instruction set that is obj ect code-comp atible with the industry standard 8051 microcontro ller. As a result, software dev elopment pac kages such as assembler s and compiler s that have been written for the 8051 are compatible with the DS 5001FP.

DS5001FP 9 of 26 Figure 5 illustrates a typical memo ry connection for a s ystem using a 128kB SRAM. Note that in this configuration, both program and data are stored in a common RAM chip Figure 6 shows a similar s ystem with using two 32kB SRAMs. The byte-wide addre ss bus connects to the SRAM address lines.
