The CY62167DV30LL-55ZXI is a 16Mb high-performance CMOS static RAM organized as 1M words by 16-bits. This device features advanced circuit design to provide ultra-low active current. This 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 significantly reduces power consumption by 99% when addresses are not toggling. The device can also be put into standby mode when deselected. The input/output pins are placed in a high-impedance state when deselected, outputs are disabled, both byte high enable and byte low enable are disabled or during a write operation. Writing to the device is accomplished by taking 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. If byte high enable is LOW, then data from I/O pins is written into the location specified on the address pins.
