256k X 8 Static Ram

he WCMA2008U1B is a high-performance CMOS static RAM organized as 256K words by 8 bits. This device features advanced circuit design to provide ultra-low active current. This is device is ideal for portable applications. The device also has an Automatic power-down feature that significantly reduces power consumption by 80% when addresses are not toggling. The device CAN be put into standby mode reducing power consumption by more than 99% when deselected (CE1 HIGH or CE2 LOW). Writing to the device is accomplished by taking Chip Enable (CE1) and Write Enable (WE) inputs LOW and Chip Enable 2 (CE2) HIGH. 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 A17). Reading from the device is accomplished by taking Chip En- able (CE1) and Output Enable (OE) LOW while forcing Write Enable (WE) and Chip Enable 2 (CE2) 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 ( CE1 HIGH or CE2 LOW), the outputs are disabled (OE HIGH), or during a write operation (CE1 LOW and CE2 HIGH and WE LOW). The WCMA2008U1B is available in a 36-ball FBGA package. By Unkown
