Combining Three Chip-Selects with One 64-Mbit Flash
The other use case is when the memory requirement exceeds 32 Mbit. In this case rather than using three 16-
Mbit flash components, use only one 64-Mbit component. Although 64 Mbit exceeds the memory space of the
DLPC900, the area saved on the PCB may out-weigh the extra cost of the flash component, and the unusable
memory space. Figure 26 shows the schematic layout to combine CS0, CS1 and CS2 with the external logic
gates,
and
the
connections
between
the
DLPC900
and
the
flash
component.
U18
is
a
Micron
MT28EW512ABA1LJS-0SIT 512-Mb flash component. U1 – U5 are the extra logic gates required to combine all
three chip-selects and invert the two additional addresses lines from the chip-selects.
