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 unlimited 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 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.
These FIFOs are fabricated using IDT’s high-speed CMOS technology.
They are designed for those applications requiring asynchronous and
simultaneous read/writes in multiprocessing and rate buffer
applications.
