CY7C109D Overview
The CY7C109D/CY7C1009D [1] is a high-performance CMOS static RAM organized as 131,072 words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE1), an active HIGH Chip Enable (CE2), an active LOW Output Enable Logic Block Diagram (OE), and tri-state drivers.The eight input and output pins (I/O0 through I/O7) are placed in a high-impedance state when:.
