8K x 9 AsyncFIFO, 3.3V

The IDT72V05 is a dual-port FIFOmemories that operate at a power supply voltage (Vcc) between 3.0V and 3.6V.Their architecture, functional operation and pin assignments are identical tothose of the IDT72V05. These devices load andempty data on a first-in/first-out basis. They use Full and Empty flags to preventdata overflow and underflow and expansion logic to allow for unlimitedexpansion capability in both word size and depth. The reads and writes are internally sequential through the use of ringpointers, with no address information required to load and unload data. Datais toggled in and out of the devices through the use of the Write and Read pins.The devices have a maximum data access time as fast as 25 ns. The devices utilize a 9-bit wide data array to allow for control and parity bitsat the user’s option. This feature is especially useful in data communicationsapplications where it is necessary to use a parity bit for transmission/receptionerror checking. They also feature a Retransmit capability that allows forreset of the read pointer to its initial position when is pulsed LOW to allow forretransmission from the beginning of data. A Half-Full Flag is available in thesingle device mode and width expansion modes. These FIFOs are fabricated using high-speed CMOS technology. It hasbeen designed for those applications requiring asynchronous and simultaneousread/writes in multiprocessing and rate buffer applications.
