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
