SMD CY7C1049-15VC (10.2mm Width) SOJ-36

512K x 8 Static RAM

is provided by an active LOW chip enable (CE), an active LOW
output enable (OE), and three-state drivers. Writing to the device is accomplished by taking 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 A18).
Reading from the device is accomplished by taking 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 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.
