FEATURES:
Choose among the following memory organizations:
IDT72V2101
262,144 x 9
IDT72V2111
524,288 x 9
Pin-compatible with the IDT72V261/72V271 and the IDT72V281/
72V291 SuperSync FIFOs
10ns read/write cycle time (6.5ns access time)
Fixed, low first word data latency time
5V input tolerant
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 EFand FFflags) 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)
High-performance submicron CMOS technology
DESCRIPTION:
The IDT72V2101/72V2111 are exceptionally deep, high speed, CMOS
First-In-First-Out(FIFO)memorieswithclockedreadandwritecontrols. These
FIFOs offer numerous improvements over previous SuperSync FIFOs,
including the 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.
The first word data latency period, from the time the first word is written to 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
previousSuperSyncdeviceshasbeeneliminatedonthisSuperSyncfamily.)
SuperSync FIFOs are particularly appropriate for network, video, telecommu-
nications,datacommunicationsandotherapplicationsthatneedtobufferlarge
amountsofdata.
