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 in standby mode reduces power consumption by more
than 99 percent when deselected (CE
1
HIGH or CE
2
LOW). The
eight input and output pins (I/O
0
through I/O
7
) are placed in a
high-impedance state when the device is deselected (CE
1
HIGH
or CE
2
LOW), the outputs are disabled (OE HIGH), or a write
operation is in progress (CE
1
LOW and CE
2
HIGH and WE
LOW).
To write to the device, take Chip Enable (CE
1
LOW and CE
2
HIGH) and Write Enable (WE) inputs LOW. Data on the eight I/O
pins is then written into the location specified on the Address pin
(A
0
through A
16
).
To read from the device, take Chip Enable (CE
1
LOW and CE
2
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 I/O pins.
