DESCRIPTION:
memories that operate at a power supply voltage (Vcc) between 3.0V and 3.6V.
Their architecture, functional operation and pin assignments are identical to
those of the IDT7201/7202/7203/7204/7205/7206. These devices load and
empty data on a first-in/first-out basis. They 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. The devices have a maximum data access time as fast as 25 ns.
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. They also feature 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.
been designed for those applications requiring asynchronous and simultane-
ous read/writes in multiprocessing and rate buffer applications.
DATA OUTPUTS
The IDT72V01/72V02/72V03/72V04/72V05/72V06 are dual-port FIFO
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 bits
These FIFOs are fabricated using high-speed CMOS technology. It has
