CY7C1021D-10VXIT

CY7C1021D-10VXIT 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. The input and output pins (I/O0 through I/O15) are placed in a high-impedance state when the device is deselected (active-low CE HIGH), outputs are disabled (active-low OE HIGH), 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). Write to the device by taking chip enable (active-low CE) and write enable (active-low WE) inputs LOW. Read from the device by taking chip enable (active-low CE) and output enable (active-low OE) LOW while forcing the write enable (active-low WE) HIGH. The device is suitable for interfacing with processors that have TTL I/P levels.
