SRAM Chip Async Single 5V 256K-Bit 32K x 8 20ns 28-Pin SOJ T/R

The CY7C199C is a high–performance CMOS Asynchronous SRAM organized as 32K by 8 bits that supports an asynchronous memory interface. The device features an automatic power–down feature that significantly reduces power consumption when deselected. See the Truth Table in this datasheet for a complete description of read and write modes. The CY7C199C is available in 28 DIP, 28 SOJ, and 28 TSOP I package(s).
