IDT72275
IDT72285
FEATURES:
Choose among the following memory organizations:
IDT72275 — 32,768 x 18
IDT72285 — 65,536 x 18
Pin-compatible with the IDT72255LA/72265LA 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
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
DESCRIPTION:
TheIDT72275/72285areexceptionallydeep,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.)
