General Description ^[1]
The CY7C194BN is a high-performance CMOS
Asynchronous SRAM organized as 64K × 4 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 data sheet for a complete
description of read and write modes.
The CY7C194BN is available in 24 DIP, 24 SOJ package(s).
