DESCRIPTION:
The IDT72421/72201/72211/72221/72231/72241/72251 SyncFIFO
are very high-speed, low-power First-In, First-Out (FIFO) memories with
clocked read and write controls. These devices have a 64, 256, 512, 1,024,
2,048, 4,096, and 8,192 x 9-bit memory array, respectively. These FIFOs are
applicableforawidevarietyofdatabufferingneedssuchasgraphics,localarea
networks and interprocessor communication.
These FIFOs have 9-bit input and output ports. The input port is controlled
by a free-running clock (WCLK), and two write enable pins (
WEN1, WEN2).
Data is written into the Synchronous FIFO on every rising clock edge when the
write enable pins are asserted. The output port is controlled by another clock
pin (RCLK) and two read enable pins (
REN1, REN2). 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.
The Synchronous FIFOs have two fixed flags, Empty (
EF) and Full (FF).
Two programmable flags, Almost-Empty (
PAE) and Almost-Full (PAF), are
provided for improved system control. The programmable flags default to
Empty+7 and Full-7 for
PAE and PAF, respectively. The programmable flag
offsetloadingiscontrolledbyasimplestatemachineandisinitiatedbyasserting
the load pin (
LD).
These FIFOs are fabricated using IDT’s high-speed submicron CMOS
technology.
