PIN DESCRIPTIONS
Addresses (A
0
–A
14
)
The Address inputs select an 8-bit memory location
during a read or write operation.
Chip Enable (
CE
)
The Chip Enable input must be LOW to enable all read/
write operations. When
CE
is HIGH, power consumption
is reduced.
Output Enable (
OE
)
The Output Enable input controls the data output buffers
and is used to initiate read operations.
Data In/Data Out (I/O
0
–I/O
7
)
Data is written to or read from the X28C256 through the
I/O pins.
Write Enable (
WE
)
The Write Enable input controls the writing of data to the
X28C256.
