Introduction

Logic-FIFOs, also known as First-In First-Out (FIFO) buffers, are used in many applications such as data processing, memory accesses, and communication systems. The 7284L15PAGI is one type of FIFO integrated circuit designed to store and retrieve data. It is designed for high-speed applications, containing up to 15 stages of 16-bit data storage. This paper will discuss the application fields of the 7284L15PAGI and its working principle.

Application Field

The 7284L15PAGI is an ideal solution for applications requiring a high-speed, high-capacity FIFO with low-power consumption. The device operates at speeds up to 100MHz and consumes only 4.9mA in full power mode. It is also designed with an 8-bit/16-bit programmable data width and is capable of storing up to 120 Megabits of data.One of the primary applications of the 7284L15PAGI is for communication systems. The device is very suitable for use in serial communication systems such as USB, HDMI, and Ethernet, allowing it to buffer and store the data passing through. As the device operates at speeds up to 100MHz and consumes only 4.9mA, it is very suitable for high-speed, low-power communications. In addition, it can also be used for video and image processing, storing video frames for efficient retrieval.The 7284L15PAGI is also used in many data processing systems. It is often used in FPGAs and ASICs to store and retrieve data at high speeds. It is suitable for applications requiring high throughput and low power consumption, such as in computer vision systems or image processing applications.

Working Principle

At the heart of the 7284L15PAGI is a FIFO buffer. The device utilizes two pointers to keep track of the data being stored and retrieved. The write pointer keeps track of the location of the next item to be written into the buffer, while the read pointer keeps track of the location of the item that is to be read from the buffer.The 7284L15PAGI utilizes an asynchronous design, meaning that the write and read operations can be performed independently. This means that the device can be used for many operations such as data buffering, storage, and retrieval without having to wait for one operation to be completed before another can be performed.In addition, the device also contains a special latency feature. This feature allows the device to store up to 15 stages of 16-bit data before it begins to overwrite the oldest data. This is useful in applications that require a long continuous period of data storage and retrieval. Finally, the 7284L15PAGI also includes a reliable Power-On Reset (POR) reset circuit. This ensures that the device is always reset when power is applied, ensuring that the data is correctly stored and retrieved.

Conclusion

The 7284L15PAGI is an ideal solution for applications requiring a high-speed, high capacity FIFO buffer. It operates at speeds up to 100MHz and consumes 4.9mA in full power mode, allowing it to be used in applications such as serial communication and data processing. The device also includes features such as latency and a POR circuit, increasing its versatility and reliability.
