CY62256NLL-70SNXC

The CY62256NLL-70SNXC is a 256kB high performance CMOS Static Random Access Memory (SRAM) organized as 32K words by 8-bit. Easy memory expansion is provided by an active LOW chip enable (CE) and active LOW output enable (OE) and tri-state drivers. This device has an automatic power-down feature, reducing the power consumption by 99.9% when deselected. An active LOW write enable signal controls the writing/reading operation of the memory. When CE and WE inputs are both LOW, data on the eight data input/output pins is written into the memory location addressed by the address present on the address pins. Reading the device is accomplished by selecting the device and enabling the outputs, CE and OE active LOW, while WE remain inactive or HIGH. Under these conditions, the contents of the location addressed by the information on address pins are present on the eight data input/output pins.
