CMOS SuperSync FIFO™

65,536 x 9

131,072 x 9

IDT72281

IDT72291

• 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

FEATURES:

• Choose among the following memory organizations:

IDT72281

IDT72291

65,536 x 9

131,072 x 9

• Pin-compatible with the IDT72261LA/72271LA SuperSync FIFOs

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

• Fixed, low first word data latency time

• 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

• Select IDT Standard timing (using EF and FF flags) or First

Word Fall Through timing (using OR and IR flags)

• Output enable puts data outputs into high impedance state

• Easily expandable in depth and width

DESCRIPTION:

TheIDT72281/72291areexceptionallydeep,highspeed,CMOSFirst-In-

First-Out(FIFO)memorieswithclockedreadandwritecontrols. TheseFIFOs

offernumerousimprovementsoverpreviousSuperSyncFIFOs,includingthe

following:

• 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 running at the higher frequency.

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

• Thefirstworddatalatencyperiod,fromthetimethefirstwordiswrittentoan

emptyFIFOtothetimeitcanberead,isnowfixedandshort. (Thevariable

clock cycle counting delay associated with the latency period found on

previousSuperSyncdeviceshasbeeneliminatedonthisSuperSyncfamily.)

SuperSyncFIFOsareparticularlyappropriatefornetwork,video,telecom-

munications,datacommunicationsandotherapplicationsthatneedtobuffer

largeamountsofdata.

• Independent Read and Write clocks (permit reading and writing

simultaneously)
