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)

• Available in the 64-pin Thin Quad Flat Pack (TQFP) and the 64-pin
