The CY7C1059DV33 is a high performance CMOS Static RAM organized as 1M 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. To write to the device， take Chip Enable （CE） and Write Enable （WE） inputs LOW. Data on the eight I/O pins （I/O0 through I/O7） is then written into the location specified on the address pins （A0 through A19）。 To read from the device， take Chip Enable （CE） and Output Enable （OE） LOW while forcing Write Enable （WE） HIGH. Under these conditions， the contents of the memory location specified by the address pins appear on the I/O pins. The eight input or output pins （I/O0 through I/O7） are placed in a high impedance state when the device is deselected （CE HIGH）， the outputs are disabled （OE HIGH）， or a write operation is in progress （CE LOW and WE LOW）。 The CY7C1059DV33 is available in 44-pin TSOP-II package with center power and ground （revolutionary） pinout.
