PIN DESCRIPTIONS
Addresses (A
0
–A
8
)
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 and recall operations. Output
Enable LOW disables a store operation regardless of
the state of
CE
,
WE
, or
NE
.
Data In/Data Out (I/O
0
–I/O
7
)
Data is written to or read from the X20C04 through the
I/O pins. The I/O pins are placed in the high impedance
state when either
CE
or
OE
is HIGH or when
NE
is LOW.
Write Enable (
WE
)
The Write Enable input controls the writing of data to
both the static RAM and stores to the E
2
PROM.
Nonvolatile Enable (
NE
)
The Nonvolatile Enable input controls all accesses to
the E
2
PROM array (store and recall functions).
