The QCOTSTM UT8Q512 Quantified Commercial Off-theShelf product is a high-performance CMOS static RAM organized as 524,288 words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (E), an active LOW Output Enable (G), and three-state drivers. This device has a power-down feature that reduces power consumption by more than 90% when deselected. Writing to the devicei s accomplished by taking Chip Enable one (E) input LOW and Write Enable (W) inputs LOW. Data on the eight I/O pins (DQ0 through DQ 7 ) is then written into the location specified on the address pins (A0 through A18 ). Reading from the device is accomplished by taking Chip Enable one (E) and Output Enable (G) LOW while forcing Write Enable (W) HIGH. Under these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins.
