CY62128EV30
MoBL® 1 Mbit (128K x 8) Static RAM
Features
Functional Description
■ Very high speed: 45 ns
The CY62128EV30 is a high performance CMOS static RAM
module organized as 128K words by 8 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 when addresses are not toggling. Placing the
device into standby mode reduces power consumption by more
