Features
Functional Description
The CY62157CV30/33 are high-performance CMOS static
RAMs organized as 512K words by 16 bits. These devices
feature 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 devices also have an automatic power-down feature that
Note:
