DESCRIPTION:

The IDT72V275/72V285 are exceptionally deep, high speed, CMOS First-In-First-Out (FIFO) memories with clocked read and write controls.

FEATURES:

• Choose among the following memory organizations:

IDT72V275 32,768 x 18

IDT72V285 65,536 x 18

• 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)

• 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

• Green parts are available, see ordering information
