IDT72255/72265 SyncFIFO
8,192 x 18, 16,384 x 18
automatically on the outputs, no read operation required. The
state of the FWFT/SI pin during Master Reset determines the
mode in use.
The IDT72255/72265 FIFOs have five flag functions,
EF
/
OR
(Empty Flag or Output Ready),
FF
/
IR
(Full Flag or Input
Ready), and
HF
(Half-full Flag). The
EF
and
FF
functions are
selected in the IDT Standard Mode.
The
IR
and
OR
functions are selected in the First Word Fall
Through Mode.
IR
indicates that the FIFO has free space to
receive data.
OR
indicates that data contained in the FIFO is
available for reading.
HF
is a flag whose threshold is fixed at the half-way point in
memory. This flag can always be used irrespective of mode.
PAE
,
PAF
can be programmed independantly to any point
in memory. They, also, can be used irrespective of mode.
Programmable offsets determine the flag threshold and can
be loaded by two methods: parallel or serial. Two default
offset settings are also provided, such that
PAE
can be set at
127 or 1023 locations from the empty boundary and the
PAF
threshold can be set at 127 or 1023 locations from the full
boundary. All these choices are made with
LD
during Master
Reset
.
In the serial method,
SEN
together with
LD
are used to load
the offset registers via the Serial Input (SI). In the parallel
method,
WEN
together with
LD
can be used to load the offset
registers via D
n
.
REN
together with
LD
can be used to read the
offsets in parallel from Q
n
regardless of whether serial or
parallel offset loading is selected.
During Master Reset (
MRS
), the read and write pointers are
set to the first location of the FIFO. The FWFT line selects IDT
Standard Mode or FWFT Mode. The
LD
pin selects one of two
partial flag default settings (127 or 1023) and, also, serial or
parallel programming. The flags are updated accordingly.
The Partial Reset (
PRS
) also sets the read and write
pointers to the first location of the memory. However, the
mode setting, programming method, and partial flag offsets
are not altered. The flags are updated accordingly.
PRS
is
useful for resetting a device in mid-operation, when repro-
