Functional Description: 
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 than 99% when deselected (CE1 HIGH
or CE2 LOW). The eight input and output pins (IO0 through
IO7) are placed in a high impedance state when the device is
deselected (CE1 HIGH or CE2 LOW), the outputs are disabled
(OE HIGH), or a write operation is in progress (CE1 LOW and
CE2 HIGH and WE LOW).
To write to the device, take Chip Enable (CE1 LOW and CE2
HIGH) and Write Enable (WE) inputs LOW. Data on the eight
IO pins is then written into the location specified on the
Address pin (A0 through A16).
To read from the device, take Chip Enable (CE1 LOW and CE2
HIGH) and Output Enable (OE) LOW while forcing Write
Enable (WE) HIGH. Under these conditions, the contents of
the memory location specified by the address pins appear on
the IO pins.

Maximum Ratings: 
Exceeding maximum ratings may impair the useful life of the
device. These user guidelines are not tested.
