Functional Description
The CY62147EV30 is a high performance CMOS static RAM
organized as 256K words by 16 bits. This device features
advanced circuit design to provide ultra low active current. It 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 when addresses are not toggling. Placing the
device into standby mode reduces power consumption by more
than 99% when deselected (CE
HIGH). The input and output pins (IO
