DESCRIPTION:
The IDT72V801/72V811/72V821/72V831/72V841/72V851/72V851 are
dual synchronous (clocked) FIFOs. The device is functionally equivalent to
two IDT72V201/72V211/72V221/72V231/72V241/72V251 FIFOs in a single
package with all associated control, data, and flag lines assigned to separate
pins.
Each of the two FIFOs (designated FIFO A and FIFO B) contained in the
IDT72V801/72V811/72V821/72V831/72V841/72V851 has a 9-bit input data
port (DA0 - DA8, DB0 - DB8) and a 9-bit output data port (QA0 - QA8,
QB0 - QB8). Each input port is controlled by a free-running clock (WCLKA,
WCLKB), and two Write Enable pins (
WENA1, WENA2, WENB1, WENB2).
DataiswrittenintoeachofthetwoarraysoneveryrisingclockedgeoftheWrite
Clock (WCLKA, WCLKB) when the appropriate Write Enable pins are
asserted.
The output port of each FIFO bank is controlled by its associated clock pin
(RCLKA, RCLKB) and two Read Enable pins (
RENA1, RENA2, RENB1,
RENB2).TheReadClockcanbetiedtotheWriteClockforsingleclockoperation
orthetwoclockscanrunasynchronousofoneanotherfordualclockoperation.
An Output Enable pin (
OEA, OEB) is provided on the read port of each FIFO
for three-state output control.
Each of the two FIFOs has two fixed flags, Empty (
EFA,EFB)andFull(FFA,
FFB). Twoprogrammableflags,Almost-Empty(PAEA,PAEB)andAlmost-Full
(
PAFA,PAFB),areprovidedforeachFIFObanktoimprovememoryutilization.
If not programmed, the programmable flags default to Empty+7 for
PAEAand
PAEB, and Full-7 for PAFA and PAFB.
The IDT72V801/72V811/72V821/72V831/72V841/72V851 architecture
lends itself to many flexible configurations such as:
2-level priority data buffering
Bidirectional operation
Width expansion
Depth expansion
This FIFO is fabricated using IDT's high-performance submicron CMOS
technology.
