The CY62167EV30LL-45BVXI is a 16Mb high performance CMOS static RAM organized as 1M words by 16-bits or 2M words by 8-bits. This device features an advanced circuit design that provides an ultra low active current. Ultra low active current is ideal for providing More Battery Life (MoBL?) in portable applications such as cellular telephones. The device also has an automatic power down feature that reduces power consumption by 99% when addresses are not toggling. Place the device into standby mode when deselected. The input and output pins are placed in a high impedance state when the device is deselected, outputs are disabled, both byte high enable and byte low enable are disabled or a write operation is in progress. To write to the device, take chip enables and write enable input LOW. If byte low enable is LOW, then data from I/O pins is written into the location specified on the address pins.
