Product Summary

The CY7C185A-35DMB is a high-performance CMOS static RAM. It is organized as 8192 words by 8 bits. Easy memory expansion is provided by an active LOW chip enable (CE1), an active HIGH chip enable (CE2), and active LOW output enable (OE) and three-state drivers. The CY7C185A-35DMB has an automatic power-down feature (CE1 or CE2), reducing the power consumption by 70% when deselected. The CY7C185A-35DMB is in a standard 300-mil-wide DIP, SOJ, or SOIC package. The input/output pins remain in a high-impedance state unless the chip is selected, outputs are enabled, and write enable (WE) is HIGH. A die coat is used to insure alpha immunity.
