3.3 VOLT CMOS SuperSync FIFO™  
65,536 x 9  
131,072 x 9  
IDT72V281  
IDT72V291  
Independent Read and Write clocks (permit reading and writing  
simultaneously)  
Available in the 64-pin Thin Quad Flat Pack (TQFP) and the 64-pin  
Slim Thin Quad Flat Pack (STQFP)  
High-performance submicron CMOS technology  
Industrial Temperature Range (-40°C to + 85°C) is available  
ꢀEATURES:  
Choose among the following memory organizations:  
IDT72V281  
IDT72V291  
65,536 x 9  
131,072 x 9  
Pin-compatible with the IDT72V261/72V271 SuperSync FIFOs  
10ns read/write cycle time (6.5ns access time)  
Fixed, low first word data latency time  
DESCRIPTION:  
Auto power down minimizes standby power consumption  
Master Reset clears entire FIFO  
Partial Reset clears data, but retains programmable  
settings  
Retransmit operation with fixed, low first word data  
latency time  
Empty, Full and Half-Full flags signal FIFO status  
Programmable Almost-Empty and Almost-Full flags, each flag can  
default to one of two preselected offsets  
The IDT72V281/72V291 are exceptionally deep, high speed, CMOS  
First-In-First-Out (FIFO) memories with clocked read and write controls.  
These FIFOs offer numerous improvements over previous SuperSync  
FIFOs,includingthefollowing:  
Thelimitationofthefrequencyofoneclockinputwithrespecttotheotherhas  
been removed. The Frequency Select pin (FS) has been removed, thus  
it is no longer necessary to select which of the two clock inputs, RCLK or  
WCLK, is runningatthe higherfrequency.  
Program partial flags by either serial or parallel means  
The period required by the retransmit operation is now fixed and short.  
Select IDT Standard timing (using EF and FF flags) or First Word Thefirstworddatalatencyperiod,fromthetimethefirstwordiswrittentoan  
Fall Through timing (using OR and IR flags)  
Output enable puts data outputs into high impedance state  
Easily expandable in depth and width  
emptyFIFOtothetimeitcanberead,isnowfixedandshort. (Thevariable  
clock cycle counting delay associated with the latency period found on  
previousSuperSyncdeviceshasbeeneliminatedonthisSuperSyncfamily.)
