Description
Data inputs for 9-bit wide data.
When
RS
is set LOW, internal READ and WRITE pointers are set to the first location of the RAM
array.
HF
and
FF
go HIGH, and
AEF
and
EF
go LOW. A reset is required before an initial WRITE
after power-up.
R
and
W
must be HIGH during
RS
cycle.
When WRITE is LOW, data can be written into the RAM array sequentially, independent of
READ. In order for WRITE to be active,
FF
must be HIGH. When the FIFO is full (
FF
-LOW),
the internal WRITE operation is blocked.
When READ is LOW, data can be read from the RAM array sequentially, independent of
WRITE. In order for READ to be active,
EF
must be HIGH. When the FIFO is empty (
EF
-LOW),
the internal READ operation is blocked. The three-state output buffer is controlled by the read
signal and the external output control
(OE
).
This is a dual-purpose input. In the single device configuration (
XI
grounded), activating
retransmit (
FL
/
RT
-LOW) will set the internal READ pointer to the first location. There is no effect
on the WRITE pointer.
R
and
W
must be HIGH before setting
FL
/
RT
LOW. Retransmit is not
compatible with depth expansion. In the depth expansion configuration,
FL
/
RT
-LOW indicates
the first activated device.
In the single device configuration,
XI
is grounded. In depth expansion or daisy chain expansion,
XI
is connected to
XO
(expansion out) of the previous device.
When
OE
is set HIGH, the data flow through the three-state output buffer is inhibited regardless
of an active READ operation. A read operation does increment the read pointer in this situation.
When
OE
is set LOW, Q
0
-Q
8
are still in a HIGH impedance condition if no READ occurs. For
a complete READ operation with data appearing on Q
0
-Q
8
, both
R
and
OE
should be asserted
LOW.
When
FF
goes LOW, the device is full and further WRITE operations are inhibited. When
FF
is HIGH, the device is not full.
When
EF
goes LOW, the device is empty and further READ operations are inhibited. When
EF
is HIGH, the device is not empty.
When
AEF
is LOW, the device is empty to 1/8 full or 7/8 to completely full. When
AEF
is HIGH,
the device is greater than 1/8 full, but less than 7/8 full.
This is a dual purpose output. In the single device configuration (
XI
grounded), the device is
more than half full when
HF
is LOW. In the depth expansion configuration (
XO
connected to
XI
of the next device), a pulse is sent from
XO
to
XI
when the last location in the RAM array is
filled.
