... SRAM, a lithium cell, and a real-time clock. This is packaged in a 72-pin SIMM module. MEMORY ORGANIZATION Figure 2 illustrates the memory map accessed by the DS5001FP. The entire 64k of program and 64k of data are potentially available to the byte-wide bus. This preserves the I/O ports for application use. The user controls the portion of memory that is actually mapped to the byte-wide bus by selecting the program range and data range ...
