Functional Description

The CY7C1049DV33 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 tristate drivers. You can write to the device by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the eight I/O pins (IO0 through IO7) is then written into the location specified on the address pins (A0 through A18).
