DESCRIPTION
The IDT72V11165/72V12165/72V13165/72V14165/72V15165 devices
are First-In, First-Out (FIFO) memories with clocked read and write controls.
These FIFOs have 16-bit input and output ports. The input port is controlled
by a free-running clock (WCLK), and an input enable pin (WEN). Data is written
into the Multimedia 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.
These Multimedia FIFOs support three fixed flags: Empty Flag (EF), Full
Flag (FF), and Half Full Flag (HF).
