Functional Description
The CY7C109B / CY7C1009B is a high-performance CMOS
static RAM organized as 131,072 words by 8 bits. Easy mem-
ory expansion is provided by an active LOW Chip Enable
(CE
1
), an active HIGH Chip Enable (CE
2
), an active LOW Out-
Logic Block Diagram
put Enable (OE), and three-state drivers. Writing to the device
is accomplished by taking Chip Enable One (CE
1
) and Write
Enable (WE) inputs LOW and Chip Enable Two (CE
2
) input
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
16
).
Reading from the device is accomplished by taking Chip En-
able One (CE
1
) and Output Enable (OE) LOW while forcing
Write Enable (WE) and Chip Enable Two (CE
2
) HIGH. Under
these conditions, the contents of the memory location speci-
fied 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
HIGH or CE
2
LOW), the outputs are disabled (OE HIGH), or
during a write operation (CE
1
LOW, CE
2
HIGH, and WE LOW).
The CY7C109B is available in standard 400-mil-wide SOJ and
32-pin TSOP type I packages. The CY7C1009B is available in
a 300-mil-wide SOJ package. The CY7C1009B and
CY7C109B are functionally equivalent in all other respects.
