NOTE:
1.
The PBGA is only available for the IDT72805LB/72815LB/72825LB in the 15 or 25 ns speed grade.
IDT72205LB/72215LB/72225LB/72235LB/72245LB FIFOs in a single package
with all associated control, data, and flag lines assigned to independent
pins. These devices are very high-speed, low-power First-In, First-Out
(FIFO) memories with clocked read and write controls. These FIFOs are
applicable for a wide variety of data buffering needs, such as optical disk
controllers, Local Area Networks (LANs), and interprocessor communication.
Each of the two FIFOs contained in these devices has an 18-bit input and
output port. Each input port is controlled by a free-running clock (WCLK), and
an input enable pin (
WEN). Data is read into the synchronous FIFO on every
clock when
WEN is asserted. The output port of each FIFO bank is controlled
by another clock pin (RCLK) and another enable pin (
REN). The Read Clock
can be tied to the Write Clock for single clock operation or the two clocks can
run asynchronous of one another for dual-clock operation. An Output Enable
pin (
OE) is provided on the read port of each FIFO for three-state control of the
output.
The synchronous FIFOs have two fixed flags, Empty Flag/Output Ready
(
EF/OR) and Full Flag/Input Ready (FF/IR), and two programmable flags,
Almost-Empty(
PAE)andAlmost-Full(PAF).Theoffsetloadingoftheprogram-
mable flags is controlled by a simple state machine, and is initiated by asserting
the Load pin (
LD). A Half-Full flag (HF) is available for each FIFO that is
implemented as a single device configuration.
There are two possible timing modes of operation with these devices: IDT
Standard mode and First Word Fall Through (FWFT) mode.
In IDT Standard Mode, the first word written to an empty FIFO will not
appear on the data output lines unless a specific read operation is performed.
A read operation, which consists of activating
REN and enabling a rising RCLK
edge, will shift the word from internal memory to the data output lines.
In FWFT mode, the first word written to an empty FIFO is clocked directly
to the data output lines after three transitions of the RCLK signal. A
REN does
not have to be asserted for accessing the first word.
These devices are depth expandable using a daisy-chain technique or First
Word Fall Through (FWFT) mode. The
XI and XO pins are used to expand the
FIFOs. In depth expansion configuration,
FLisgroundedonthefirstdeviceand
set to HIGH for all other devices in the Daisy Chain.
The IDT72805LB/72815LB/72825LB/72835LB/72845LB are fabricated
using IDT’s high-speed submicron CMOS technology.
