The CY7C128A is a high-performance CMOS static RAM organized as 2048 words by 8 bits. Easy memory expansion is provided by an active LOW chip enable (CE), and active LOW output enable (OE) and three-state drivers. The CY7C128A has an automatic power-down feature, reducing the power consumption by 83% when deselected. Writing to the device is accomplished when the chip enable (CE) and write enable (WE) inputs are both LOW. Data on the eight I/O pins (I/O0 through I/O7) is written into the memory location specified on the address pins (A0 through A10).
