Figure 7-15 shows how to minimize board space by selecting the next larger density of flash memory. For example, if two 4-megabyte flash components are needed, then selecting one 8-megabyte flash component can be considered. This will save board space because only one component takes up space on the board rather than two components.
When calculating the appropriate amount of memory to use, do not mix densities to come up with the exact amount of memory that is calculated. Always use the same densities of flash memory even if it exceeds the amount of memory that is calculated.
