Functional Description
The CY62256V is a high-performance CMOS static RAM organized as 32,768 words by 8 bits. Easy memory expansion is provided by an active LOW chip enable (CE) and active LOW output enable (OE) and three-state drivers. This device has an automatic power-down feature, reducing the power consumption by 98% when deselected. The CY62256V is in the standard 450-mil-wide (300-mil body width) SOIC, TSOP, and reverse TSOP packages.
