DESCRIPTION:
IDT72021/031/041s are high-speed, low-power, dual-port
memory devices commonly known as FIFOs (First-In/First-
Out). Data can be written into and read from the memory at
independent rates. The order of information stored and ex-
tracted does not change, but the rate of data entering the FIFO
might be different than the rate leaving the FIFO. Unlike a
Static RAM, no address information is required because the
read and write pointers advance sequentially. The IDT72021/
031/041s can perform asynchronous and simultaneous read
and write operations. There are four status flags, (
HF
,
FF
,
EF
,
AEF
) to monitor data overflow and underflow. Output Enable
(
OE
) is provided to control the flow of data through the output
port. Additional key features are Write (
W
), Read (
R
), Retrans-
mit (
RT
), First Load (
FL
), Expansion In (
XI
) and Expansion Out
(
XO
). The IDT72021/031/041s are designed for those appli-
cations requiring data control flags and Output Enable (
OE
) in
multiprocessing and rate buffer applications.
The IDT72021/031/041s are fabricated using IDT’s CMOS
technology. Military grade product is manufactured in compli-
ance with the latest version of MIL-STD-883, Class B, for high
reliability systems.
