DESCRIPTION:
The IDT72420/72200/72210/72220/72230/72240
SyncFIFO
are very high-speed, low-power First-In, First-
Out (FIFO) memories with clocked read and write controls.
The IDT72420/72200/72210/72220/72230/72240 have a 64,
256, 512, 1024, 2048, and 4096 x 8-bit memory array, respec-
tively. These FIFOs are applicable for a wide variety of data
buffering needs, such as graphics, Local Area Networks
(LANs), and interprocessor communication.
These FIFOs have 8-bit input and output ports. The input
port is controlled by a free-running clock (WCLK), and a write
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 a read enable pin
(REN). 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 (OE) is
provided on the read port for three-state control of the output.
These Synchronous FIFOs have two end-point flags, Empty
(EF) and Full (FF). Two partial flags, Almost-Empty (AE) and
Almost-Full (AF), are provided for improved system control.
The partial ( AE) flags are set to Empty+7 and Full-7 for AE and
AF respectively.
The IDT72420/72200/72210/72220/72230/72240 are fabri-
cated using IDT’s high-speed submicron CMOS technology.
Military grade product is manufactured in compliance with the
latest revision of MIL-STD-883, Class B.
