SRAM Chip Async Single 5V 256K-Bit 32K x 8 20ns 28-Pin TSOP-I

The CY7C199CN[1] 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 reduces power consumption when deselected. See the Truth Table on page 4 in this data sheet for a complete description of read and write modes. The CY7C199CN is available in 28-pin molded SOJ and 28-pin DIP package(s).
