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. Figure 26. One 64-Mbit Flash Component |
