DESCRIPTION:
The IDT7280/7281/7282/7283/7284/7285 are dual-FIFO memories that
load and empty data on a first-in/first-out basis. These devices are functional
and compatible to two IDT7200/7201/7202/7203/7204/7205 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 unlimted expansion capability in both
word size and depth.
The reads and writes are internally sequential through the use of ring 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.
The devices utilize a 9-bit wide data array to allow for control and parity bits
at the users option. This feature is especially useful in data communications
applications where it is necessary to use a parity bit for transmssion/reception
error checking. It also features a Retransmt (
RT
) capability that allows for reset
of the read pointer to its initial position when
RT
is pulsed LOW to allow for
retransmssion fromthe beginning of data. A Half-Full Flag is available in the
single device mode and width expansion modes.
These FIFOs are fabricated using IDT’s high-speed CMOS technology.
They are designed for those applications requiring asynchronous and simul-
taneous read/writes in multiprocessing and rate buffer applications.
