CMOS SuperSync FIFO™  
32,768 x 18  
65,536 x 18  
IDT72275  
IDT72285  
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  
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  
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  
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  
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

clock cycle counting delay associated with the latency period found on  
previousSuperSyncdeviceshasbeeneliminatedonthisSuperSyncfamily.)
