Functional Description
The CY7C1012AV33 is a high-performance CMOS static RAM
organized as 512K words by 24 bits. Each data byte is
separately controlled by the individual chip selects (CE

,
CE

). CE

. This device has an automatic
power-down feature that significantly reduces power
consumption when deselected.
Writing the data bytes into the SRAM is accomplished when
the chip select controlling that byte is LOW and the write
enable input (WE) input is LOW. Data on the respective
input/output (I/O) pins is then written into the location specified
on the address pins (A
0
–
A
18
). Asserting all of the chip selects
LOW and write enable LOW will write all 24 bits of data into
the SRAM. Output enable (OE) is ignored while in WRITE
mode.
Data bytes can also be individually read from the device.
Reading a byte is accomplished when the chip select
controlling that byte is LOW and write enable (WE) HIGH while
output enable (OE) remains LOW. Under these conditions, the
contents of the memory location specified on the address pins
will appear on the specified data input/output (I/O) pins.
Asserting all the chip selects LOW will read all 24 bits of data
from the SRAM.
The 24 I/O pins (I/O
0
–
I/O
23
) are placed in a high-impedance
state when all the chip selects are HIGH or when the output
enable (OE) is HIGH during a READ mode. For further details,
refer to the truth table of this data sheet.
The CY7C1012AV33 is available in a standard 119-ball BGA.
