DESCRIPTION:
load and empty data on a first-in/first-out basis. These devices are functional and
compatible to two IDT72V01/72V02/72V03/72V04/72V05 FIFOs in a single
package with all associated control, data, and flag lines assigned to separate
pins. The devices use Full and Empty flags to prevent data overflow and
underflow and expansion logic to allow for unlimited expansion capability in both
word size and depth.
pointers, with no address information required to load and unload data. Data
is toggled in and out of the devices through the use of the Write (W) and Read
(R) pins.
bits at the user’s option. This feature is especially useful in data communications
applications where it is necessary to use a parity bit for transmission/reception
error checking. It also features a Retransmit (RT) capability that allows for reset
of the read pointer to its initial position when RT is pulsed low to allow for
retransmission from the beginning of data. A Half-Full Flag is available in the
single device mode and width expansion modes.
They are designed for those applications requiring asynchronous and simul-
taneous read/writes in multiprocessing and rate buffer applications.
RB
The IDT72V81/72V82/72V83/72V84/72V85 are dual-FIFO memories that
The reads and writes are internally sequential through the use of ring
The devices utilize a 9-bit wide data array to allow for control and parity
These FIFOs are fabricated using IDT’s high-speed CMOS technology.
