CY7C1049-25VM_1334675

The CY7C1049 is a high-performance CMOS static RAM or- ganized as 524,288 words by 8 bits. Easy memory expansion is provided by an active LOW chip enable (CE), an active LOW
output enable (OE), and three-state drivers. Writing to the de- vice is accomplished by taking chip enable (CE) and write en- able (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 A18).
Reading from the device is accomplished by taking chip en- able (CE) and output enable (OE) LOW while forcing write en- able (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins.
The eight input/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 during a write operation (CE LOW, and WE LOW).
The CY7C1049 is available in a standard 400-mil-wide 36-pin SOJ package with center power and ground (revolutionary) pinout.
