... M40SZ100Y, M40SZ100W OPERATION The M40SZ100Y/W, as shown in Figure 7, page 5, can control one (two, if placed in parallel) standard low-power SRAM. This SRAM must be configured to have the chip enable input disable all other input signals. Most slow, low-power SRAMs are config- ured like this, however many fast SRAMs are not. ...
