The read clock can be tied to the write clock for single clock operation or the
twoclockscanrunasynchronousofoneanotherfordual-clockoperation. An
Output Enable pin (OE) is provided on the read port for three-state control of
theoutput.
The synchronous FIFOs have two fixed flags, Empty (EF) and Full (FF),
andtwoprogrammableflags,Almost-Empty(PAE)andAlmost-Full(PAF).The
offsetloadingoftheprogrammableflagsiscontrolledbyasimplestatemachine,
andisinitiatedbyassertingtheLoadpin(LD). AHalf-Fullflag(HF)isavailable
when the FIFO is used in a single device configuration.
ThesedevicesaredepthexpandableusingaDaisy-Chaintechnique.The
XI and XO pins are used to expand the FIFOs. In depth expansion configu-
ration, First Load (FL) is grounded on the first device and set to HIGH for all
other devices in the Daisy Chain.
The IDT72205LB/72215LB/72225LB/72235LB/72245LB is fabricated
using high-speed submicron CMOS technology.
