CY7C1021DV33-10ZSXIT is a high-performance CMOS static RAM organized as 65,536 words by 16 bits. This device has an automatic power-down feature that significantly reduces power consumption when deselected. Writing to the device is accomplished by taking chip enable (active-low CE) and write enable (active-low WE) inputs LOW. Reading from the device is accomplished by taking chip enable (active-low CE) and output enable (active-low OE) LOW while forcing the write enable (active-low WE) HIGH. The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when the device is deselected (active-low CE HIGH), the outputs are disabled (active-low OE HIGH), the active-low BHE and active-low BLE are disabled (active-low BHE, active-low BLE HIGH), or during a write operation (active-low CE LOW, and active-low WE LOW).
