The CY7C1012AV33 is a high-performance CMOS static RAM organized as 512K words by 24 bits. Each data byte is separately controlled by the individual chip selects (CE0, CE1, CE2). CE0 controls the data on the I/O0I/O7, while CE1 controls the data on I/O8I/O15, and CE2 controls the data on the data pins I/O16I/O23. This device has an automatic power-down feature that significantly reduces power consumption when deselected.
