Functional Description
The CY62128EV30
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
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
input and output pins (IO
impedance state when the device is deselected (CE
CE
LOW), the outputs are disabled (OE HIGH), or a write
2
operation is in progress (CE
LOW).
To write to the device, take Chip Enable (CE
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 CE
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.

14.The internal write time of the memory is defined by the overlap of WE

terminate a write by going INACTIVE. The data input setup and hold timing should be referenced to the edge of the signal that terminates the write.
