DESCRIPTION:
72801/72811/72821/72831/72841 are dual synchronous
(clocked) FIFOs. The device is functionally equivalent to two
72201/72211/72221/72231/72241 FIFOs in a single package
with all associated control, data, and flag lines assigned to
separate pins.
Each of the two FIFOs (designated FIFO A and FIFO B)
contained in the 72801/72811/72821/72831/72841 has a 9-
bit input data port (DA0 - DA8), DB0 - DB8) and a 9-bit output
data port (QA0 - QA8, QB0 - QB8). Each input port is
controlled by a free-running clock(WCLKA, WCLKB), and two
write enable pins (
WENA1
, WENA2,
WENB1
, WENB2). Data
is written into each of the two arrays on every rising clock edge
of the write clock (WCLKA WCLKB) when the appropriate
write enable pins are asserted.
The output port of each FIFO bank is controlled by its
associated clock pin (RCLKA, RCLKB) and two read enable
pins (
RENA1
,
RENA2
,
RENB1
,
RENB2
). The read clock can
be tied to the write clock for single clock operation or the two
clocks can run asynchronous of one another for dual clock
operation. An output enable pin (
OEA
,
OEB
) is provided on the
read port of each FIFO for three-state output control .
Each of the two FIFOs has two fixed flags, empty (
EFA
,
EFB
)
and full (
FFA
,
FFB
). Two programmable flags, almost-empty
(
PAEA
,
PAEB
) and almost-full (
PAFA
,
PAFB
), are provided for
