• 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
