Functional Description
The CY62148BN is a high performance CMOS static RAM organized as 512K words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE), an active LOW Output Enable (OE), and tri-state drivers. This device has an automatic power down feature that reduces power consumption by more than 99% when deselected.
