DS5002FP Secure Microprocessor Chip
Figure 13
illustrates a typical memory connection for a system using a 128kB SRAM. Note that in this configuration,
both program and data are stored in a common RAM chip.
Figure 14
shows a similar system with using two 32kB
SRAMs. The byte-wide address bus connects to the SRAM address lines. The bidirectional byte-wide data bus
connects the data I/O lines of the SRAM.
