18 / 216 page  16 S75WS256Nxx Based MCPs S75WS-N-00_A0 February 17, 2005 Ad van c e Inf o rmation 5.4 Look-Ahead Connection Diagram Look Ahead Pinout – 1.8 V only x 16NOR + x16pSRAM + x16MirrorBit Data Notes: 1. F1 and F2 denote XIP/Code Flash, while F3 and F4 denote Data/Companion Flash 2. In addition to being defined as F2-CE#, Ball C5 can also be assigned as F1-CE2# for code that has two chip enable signals. Figure 5.2 Look Ahead Pinout – 1.8 V only x 16NOR + x16pSRAM + x16MirrorBit Data To provide customers with a migration path to higher densities, as well as the option to stack more die in a package, Spansion has prepared a standard pinout that supports: NOR Flash and SRAM densities up to 4 Gigabits NOR Flash and PSRAM densities up to 4 Gigabits NOR Flash and PSRAM and DATA STORAGE densities up to 4 Gigabits The signal locations of the resultant MCP device are shown above. Note that for different densi- ties, the actual package outline may vary. However, any pinout in any MCP will be a subset of the pinout above.
