- 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 AlmostEmpty 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 (BGA Only)
