Features
Functional Description
The CY62167DV18 is a 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
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. Placing the device into standby mode reduces power
