Alliance Memory SRAM, CY62256NLL-55SNXI- 2Mbit

The Alliance Memory CMOS Static RAM is organized as 32K words by 8 bits. It offers easy memory expansion with active LOW chip enable (CE) and output enable (OE), featuring tristate drivers. The device includes an automatic power-down feature that reduces power consumption by 99.9% when deselected. An active LOW write enable signal controls the writing and reading operations. Data is written when CE and WE inputs are both LOW. For reading, the device is selected, and the outputs are enabled while WE remains HIGH. The input or output pins are in a high-impedance state unless the chip is selected, outputs are enabled, and WE is HIGH.
