CY7C1061AV33
16-Mbit (1 M × 16) Static RAM
Features
■
Functional Description
The CY7C1061AV33 is a high performance CMOS Static RAM
organized as 1,048,576 words by 16 bits.
To write to the device, enable the chip (CE
1
LOW and CE
2
HIGH)
while forcing the Write Enable (WE) input LOW. If Byte Low
Enable (BLE) 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
19
). If Byte High Enable (BHE) 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
19
).
To read from the device, enable the chip by taking CE
1
LOW and
CE
2
HIGH while forcing the Output Enable (OE) LOW and the
Write Enable (WE) HIGH. If Byte Low Enable (BLE) 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 High Enable (BHE) is LOW, then
data from memory will appear on I/O
8
to I/O
15
. See
for a complete description of Read and Write modes.
The input/output pins (I/O
0
through I/O
15
) are placed in a
high-impedance state when the device is deselected (CE
1
HIGH/CE
2
LOW), the outputs are disabled (OE HIGH), the BHE
and BLE are disabled (BHE, BLE HIGH), or a Write operation is
in progress (CE
1
LOW, CE
2
HIGH, and WE LOW).
