The CY7C1069AV33 is a high-performance CMOS Static RAM organized as 2,097,152 words by 8 bits. Writing to the device is accomplished by enabling the chip (by taking /CE1 LOW and CE2 HIGH) and Write Enable (/WE) inputs LOW. Reading from the device is accomplished by enabling the chip (/CE1 LOW and CE2 HIGH) as well as forcing the Output Enable (/OE) LOW while forcing the Write Enable (/WE) HIGH. See the truth table at the back of this data sheet for a complete description of Read and Write modes. The input/output pins (I/O0 through I/O7) are placed in a high-impedance state when the device is deselected (/CE1 HIGH or CE2 LOW), the outputs are disabled (/OE HIGH), or during a Write operation (/CE1 LOW, CE2 HIGH, and /WE LOW). The CY7C1069AV33 is available in a 54-pin TSOP II package with center power and ground (revolutionary) pinout, and a 48-ball fine-pitch ball grid array (FBGA) package.
