Functional Description
The CY7C1062DV33 is a high-performance CMOS Static
RAM organized as 524,288 words by 32 bits.
Writing to the device is accomplished by enabling the chip
(CE
1,
CE
2
and CE
3
LOW) and forcing the Write Enable (WE)
input LOW. If Byte Enable A (B
A
) is LOW, then data from I/O
pins (I/O
0
through I/O
7
), is written into the location specified on
the address pins (A
0
through A
18
). If Byte Enable B (B
B
) is
LOW, then data from I/O pins (I/O
8
through I/O
15
) is written into
the location specified on the address pins (A
0
through A
18
).
Likewise, B
C
and B
D
correspond with the I/O pins I/O
16
to I/O
23
and I/O
24
to I/O
31
, respectively.
Reading from the device is accomplished by enabling the chip
(CE
1,
CE
2
,
and CE
3
LOW) while forcing the Output Enable
(OE) LOW and Write Enable (WE) HIGH. If the first Byte
Enable (B
A
) is LOW, then data from the memory location
specified by the address pins will appear on I/O
0
to I/O
7
. If Byte
Enable B (B
B
) is LOW, then data from memory will appear on
I/O
8
to I/O
15
. Similarly, B
c
and B
D
correspond to the third and
fourth bytes. See the truth table at the back of this data sheet
for a complete description of read and write modes.
The input/output pins (I/O
0
through I/O
31
) are placed in a
high-impedance state when the device is deselected (CE
1,
CE
2
or CE
3
HIGH), the outputs are disabled (OE HIGH), the
byte selects are disabled (B
A-D
HIGH), or during a write
operation (CE
1,
CE
2
, and CE
3
LOW, and WE LOW).
The CY7C1062DV33 is available in 119-ball plastic ball grid
array (PBGA) package.
