INTRODUCTION
The UT8ER512K32 is a high-performance CMOS static RAM organized as 524,288 words by 32 bits. Easy memory expansion is provided by active LOW and HIGH chip enables (E1, E2), 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 device is accomplished by driving chip enable one (E1) input LOW, chip enable two (E2) HIGH and write enable (W) input LOW. Data on the 32 I/O pins (DQ0 through DQ31) 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 (E1) and output enable (G) LOW while forcing write enable (W) and chip enable two (E2) HIGH. Under these conditio...
