Functional Description
[1]
The CY62158DV30 is a high-performance CMOS static RAMs
organized as 1024K 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. The device can be put into
standby mode reducing power consumption by 85% when
deselected (CE
1
HIGH or CE
2
LOW).
Writing to the device is accomplished by taking Chip Enable 1
(CE
1
) and Write Enable (WE) inputs LOW and Chip Enable 2
(CE
2
) HIGH. Data on the eight I/O pins (I/O
0
through I/O
7
) is
then written into the location specified on the address pins (A
0
through A
19
).
Reading from the device is accomplished by taking Chip
Enable 1 (CE
1
) and Output Enable (OE) LOW and Chip
Enable 2 (CE
2
) HIGH while forcing Write Enable (WE) HIGH.
Under these conditions, the contents of the memory location
specified by the address pins will appear on the I/O pins.
The eight input/output pins (I/O
0
through I/O
7
) are placed in a
high-impedance state when the device is deselected (CE
1
LOW and CE
2
HIGH), the outputs are disabled (OE HIGH), or
during a write operation (CE
1
LOW and CE
2
HIGH and WE
LOW). See the truth table for a complete description of read
and write modes.
