Integrated Device Technology, Inc.  
FEATURES:  
• 64 x 8-bit organization (IDT72420)  
• 256 x 8-bit organization (IDT72200)  
• 512 x 8-bit organization (IDT72210)  
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.  
TheseSynchronousFIFOshavetwoend-pointflags, Empty  
(EF) and Full (FF). Two partial flags, Almost-Empty (AE) and  
Almost-Full (AF), are provided for improved system control.  
Thepartial(AE)flagsaresettoEmpty+7andFull-7forAE and  
AF respectively.  
• 1024 x 8-bit organization (IDT72220)  
• 2048 x 8-bit organization (IDT72230)  
• 4096 x 8-bit organization (IDT72240)  
• 12 ns read/write cycle time (IDT72420/72200/72210)  
• 15 ns read/write cycle time (IDT72220/72230/72240)  
• Read and write clocks can be asynchronous or  
coincidental  
• Dual-Ported zero fall-through time architecture  
• Empty and Full flags signal FIFO status  
• Almost-empty and almost-full flags set to Empty+7 and  
Full-7, respectively  
• Output enable puts output data bus in high-impedance  
state  
• Produced with advanced submicron CMOS technology  
• Available in 28-pin 300 mil plastic DIP and 300 mil  
ceramic DIP  
• For surface mount product please see the IDT72421/  
72201/72211/72221/72231/72241 data sheet  
• Military product compliant to MIL-STD-883, Class B  
• Industrial temperature range (-40OC to +85OC) is  
available, tested to military electrical specifications  
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.
