DESCRIPTION:
The IDT72V205/72V215/72V225/72V235/72V245 are functionally com-
patible versions of the IDT72205LB/72215LB/72225LB/72235LB/72245LB,
designed to run off a 3.3V supply for exceptionally low power consumption.
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.
These FIFOs have 18-bit input and output ports. The 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 is controlled by another clock pin (RCLK) and another enable pin (REN).
The Read Clock(RCLK) 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 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) and Almost-Full (PAF). The offset loading of the program-
