DESCRIPTION:
The IDT72261/72271 are monolithic, CMOS, high capac-
ity, high speed, low power first-in, first-out (FIFO) memories
with clocked read and write controls. These FIFOs are
applicable for a wide variety of data buffering needs, such as
optical disk controllers, local area networks (LANs), and inter-
processor communication.
Both FIFOs have a 9-bit input port (D
n
) and a 9-bit output
port (Q
n
). The input port is controlled by a free-running clock
(WCLK) and a data input enable pin (
WEN
). Data is written
into the synchronous FIFO on every clock when
WEN
is
asserted. The output port is controlled by another clock pin
(RCLK) and enable pin (
REN
). The read clock can be tied to
the write clock for single clock operation or the two clocks can
run asynchronously for dual clock operation. An output
enable pin (
OE
) is provided on the read port for three-state
control of the outputs.
The IDT72261/72271 have two modes of operation: In the
IDT Standard Mode
, the first word written to the FIFO is
deposited into the memory array. A read operation is required
to access that word. In the
First Word Fall Through Mode
(FWFT), the first word written to an empty FIFO appears
automatically on the outputs, no read operation required. The
