PRELIMINARY
CY7C1022
32K x 16 Static RAM
Features
5.0V operation (± 10%) High speed — tAA = 12 ns Low active power — 825 mW (max., 10 ns, “L” version) Very Low standby power — 500 µW (max., “L” version) Automatic power-down when deselected Independent Control of Upper and Lower bytes Available in 400-mil SOJ enable (BLE) is LOW, then data from I/O pins (I/O1 through I/O8), is written into the location specified on the address pins (A0 through A14). If byte high enable (BHE) is LOW, then data from I/O pins (I/O9 through I/O16) is written into the location specified on the address pins (A0 through A14). Reading from the device is accomplished by taking chip enable (CE) HIGH and output enable (OE) LOW while forcing the write enable (WE) HIGH. If byte low enable (BLE) is LOW, then data from the memory location specified by the address pins will appear on I/O1 to I/O8. If byte high enable (BHE) is LOW, then data from memory will appear on I/O9 to I/O16. See the truth table at the back of this data sheet for a complete description of read and write modes. The input/output pins (I/O1 through I/O16) are placed in a high-impedance state when the device is deselected (CE LOW), the outputs are disabled (OE HIGH), the BHE and BLE are disabled (BHE, BLE HIGH), or during a write operation (CE HIGH, and WE LOW). The CY7C1022 is available in standard 400-mil-wide SOJ packages.
