NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliabilty.
The IDT72V01/72V02/72V03/72V04 are dual-port FIFO 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. 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.
The reads and writes are internally sequential through the use of ring pointers, with no address information required to load and unload data. IDT72V01/72V02/72V03/72V04 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.
The IDT72V01/72V02/72V03/72V04 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. 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
The IDT72V01/72V02/72V03/72V04 is fabricated using IDT's high-speed CMOS technology. It has been designed for those applications requiring asynchronous and simultaneous read/writes in multiprocessing and rate buffer applications.
