PIN DESCRIPTIONS
Addresses (A
0

12
)
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 con-
sumption is reduced.
Output Enable (OE)
The Output Enable input controls the data output buff-
ers 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 X28HC64 through
the I/O pins.
Write Enable (WE)
The Write Enable input controls the writing of data to
the X28HC64.
