The CY7C1024AV33 is a high-performance CMOS static RAM organized as 131,072 words by 24 bits. Easy memory expansion is provided by an active LOW CE1, CE3, active HIGH CE2, an active LOW Output Enable (OE), and three-state drivers. This device has an automatic power-down feature that significantly reduces power consumption when deselected.

Writing to CY7C1024AV33 is accomplished by taking Chip Enable (CE1, CE2, CE3) active and Write Enable (WE) inputs LOW. Data on the 24 I/O pins (I/O₀ through I/O₂₃) is then written into the location specified on the address pins (A₀ through A₁₆).

Reading from CY7C1024AV33 is accomplished by taking Chip Enable (CE1, CE2, CE3) active and Output Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins.

The 24 input/output pins (I/O₀ through I/O₂₃) are placed in a high-impedance state when CY7C1024AV33 is deselected (CE HIGH), the outputs are disabled (OE HIGH), or during a write operation (CE1, CE3 LOW, CE2 HIGH, and WE LOW).

The CY7C1024AV33 is available in a standard 119-ball BGA package and a 100-pin TQFP package.
