DESCRIPTION:

•

Pin-compatible with the IDT72V261/72V271 and the IDT72V281/

72V291 SuperSync FIFOs

The IDT72V2101/72V2111 are exceptionally deep, high speed, CMOS

First-In-First-Out(FIFO)memorieswithclockedreadandwritecontrols. These

FIFOs offer numerous improvements over previous SuperSync FIFOs,

includingthefollowing:

• Thelimitationofthefrequencyofoneclockinputwithrespecttotheotherhas

been removed. The Frequency Select pin (FS) has been removed, thus

itis nolongernecessarytoselectwhichofthe twoclockinputs, RCLKor

WCLK, is runningatthe higherfrequency.

• The period required by the retransmit operation is now fixed and short.

• Thefirstworddatalatencyperiod,fromthetimethefirstwordiswrittentoan

emptyFIFOtothetimeitcanberead,isnowfixedandshort. (Thevariable

clockcyclecountingdelayassociatedwiththelatencyperiodfound on

previousSuperSyncdeviceshasbeeneliminatedonthisSuperSyncfamily.)

SuperSyncFIFOsareparticularlyappropriatefornetwork,video,telecommu-

nications,datacommunicationsandotherapplicationsthatneedtobufferlarge

amountsofdata.

• 10ns read/write cycle time (6.5ns access time)

• Fixed, low first word data latency time

• 5V input tolerant

• 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

• Program partial flags by either serial or parallel means

• SelectIDTStandardtiming(usingEFandFFflags)orFirstWordFall

Through timing (using OR and IR flags)

•

Output enable puts data outputs into high impedance state

• Easily expandable in depth and width

• Independent Read and Write clocks (permit reading and writing
