DESCRIPTION:

The IDT72V36100/72V36110 are exceptionally deep, high speed, CMOS First-In-First-Out (FIFO) memories with clocked read and write controls and a flexible Bus-Matching x36/x18/x9 data flow. These FIFOs offer several key user benefits:

? Flexible x36/x18/x9 Bus-Matching on both read and write ports

? The period required by the retransmit operation is 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 fixed and short.

? Asynchronous/Synchronous translation on the read or write ports

? High density offerings up to 4 Mbit

FEATURES:

? Choose among the following memory organizations:

IDT72V36100 - 65,536 x 36

IDT72V36110 - 131,072 x 36

? Higher density, 2Meg and 4Meg SuperSync II FIFOs

? Up to 166 MHz Operation of the Clocks

? User selectable Asynchronous read and/or write ports (PBGA Only)

? User selectable input and output port bus-sizing

- x36 in to x36 out

- x36 in to x18 out

- x36 in to x9 out

- x18 in to x36 out

- x9 in to x36 out

? Big-Endian/Little-Endian user selectable byte representation

? 5V input tolerant

? Fixed, low first word latency

? Zero latency retransmit

? Auto power down minimizes standby power consumption

? Master Reset clears entire FIFO

? Partial Reset clears data, but retains programmable settings

? Empty, Full and Half-Full flags signal FIFO status

? Programmable Almost-Empty and Almost-Full flags, each flag can

default to one of eight preselected offsets

? Selectable synchronous/asynchronous timing modes for Almost

Empty and Almost-Full flags

? Program programmable 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

? JTAG port, provided for Boundary Scan function (PBGA Only)

? Independent Read and Write Clocks (permit reading and writing

simultaneously)

? Available in a 128-pin Thin Quad Flat Pack (TQFP) or a 144-pin Plastic

Ball Grid Array (PBGA) (with additional features)

? Pin compatible to the SuperSync II (IDT72V3640/72V3650/72V3660/

72V3670/72V3680/72V3690) family

? High-performance submicron CMOS technology

? Industrial temperature range (–40°C to +85°C) is available

? Green parts available, see ordering information
