IDT72V275  
IDT72V285  
Slim Thin Quad Flat Pack (STQFP)  
FEATURES:  
High-performance submicron CMOS technology  
Industrial temperature range (-40°C to +85°C) is available  
Choose among the following memory organizations:  
IDT72V275  
IDT72V285  
32,768 x 18  
65,536 x 18  
DESCRIPTION:  
Pin-compatible with the IDT72V255/72V265 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)  
The IDT72V275/72V285 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, includingthe following:  
Thelimitationofthefrequencyofoneclockinputwithrespecttotheother  
has beenremoved. TheFrequencySelectpin(FS)has beenremoved,  
thusitisnolongernecessarytoselectwhichofthetwoclockinputs,RCLK  
or WCLK, is running at the higher frequency.  
The period required by the retransmit operation is now fixed and short.  
Thefirstworddatalatencyperiod,fromthetimethefirstwordiswrittento  
an empty FIFO to the time it can be read, is now fixed and short. (The  
variable clock cycle counting delay associated with the latency period  
found on previous SuperSync devices has been eliminated on this  
SuperSyncfamily.)  
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)  
SuperSyncFIFOsareparticularlyappropriatefornetwork,video,telecom-  
munications,datacommunicationsandotherapplicationsthatneedtobuffer  
largeamountsofdata.  
Available in the 64-pin Thin Quad Flat Pack (TQFP) and the 64-pin
