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 IO pins (IO
0
through
IO
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 IO pins (IO
8
through IO
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 IO
0
to IO
7
. If Byte High Enable
(BHE) is LOW, then data from memory will appear on IO
8
to
IO
15
. See
for a complete description
of Read and Write modes.
The input/output pins (IO
0
through IO
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).
