8,192 x 18
IDT72265LA
16,384 x 18
Pin-compatible with the IDT72275/72285 SuperSync FIFOs
10ns read/write cycle time (8ns 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:
The IDT72255LA/72265LA are exceptionally deep, high
speed, CMOS First-In-First-Out (FIFO) memories with clocked
read and write controls. These FIFOs offer numerous improve-
ments over previous SuperSync FIFOs, including the following:
The limitation of the frequency of one clock input with
respect to the other has 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.
