Functional Description[1]

The CY62256VN family is composed of two high-performance CMOS static RAM’s organized as 32K words by 8 bits. Easy memory expansion is provided by an active LOW chip enable (CE) and active LOW output enable (OE) and tri-state drivers. These devices have an automatic power-down feature, reducing the power consumption by over 99 when deselected.
