General Description
1
The CY7C199C is a high鈥損erformance CMOS Asynchronous
SRAM organized as 32K by 8 bits that supports an
asynchronous memory interface. The device features an
automatic power鈥揹own 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).
