FIFO (First In First Out) memory refers to a type of memory buffer in which the data is stored and retrieved in a sequence controlled by two pointers. FIFO memory is often used in digital logic to assist in the communication between two or more devices that are operating at different speeds. It is also used in embedded applications such as industrial communication networks, signal processing, and control systems. 72T18115L5BBI is one of the most popular FIFO memory solutions with features, including a relatively large number of bits and solid-state storage capabilities.

The 72T18115L5BBI FIFO memory is designed to store a large number of data words. It is based on a dual-ported memory and utilizes a single-byte pointer to address the data in the FIFO buffer. It has a 64-bit wide port and four independent ports, each with two byte control and two byte of data. The data in the FIFO memory is accessed in a “Last In, First Out” (LIFO) format, meaning that the word stored last will be read first. This is in contrast to the “First In, First Out” format used in regular RAM memory.

The FIFO memory has a variety of applications in various industries. For example, in industrial automation, it is often used to buffer signals from or to multiple devices, particularly when the devices are operational at different rates. In production lines, it can be used to buffer and store parts to ensure continuous production. It can also be used in data transfer applications and in the design of private communication networks. In the field of embedded systems, FIFO memory plays an important role in streamlining data transfer between further components within a system.

The working principle of 72T18115L5BBI FIFO memory is simple yet type-specific. Its core is a normal dual-port memory consisting of an input port and an output port. Data is written to the FIFO memory via the input port and then transferred to the output port when it is full. The FIFO memory has two internal register or counters. The read pointer keeps track of the address of the last word that has been read from the FIFO memory for data transfer. The write pointer keeps track of the address associated with the last word written to the FIFO memory. The contents of these register are incremented each time data is read or written. As the FIFO memory is filled by writing data to the input port, the write pointer is incremented, while the read pointer remains stationary.

Once the FIFO memory has been filled, the read pointer is incremented and data is read from the output port. The read pointer then marches ahead of the write pointer. When all the data in the FIFO memory has been read out, the read and write pointers will be in the same position, at which point the FIFO memory is empty. This is the main operating principle of the 72T18115L5BBI FIFO memory.

In summary, 72T18115L5BBI FIFO memory is a type of memory buffer used in many digital logic communication applications. It is based on a normal dual-port memory and is designed to store many data words in a LIFO format. Its main application is in industrial automation, private communication networks, digital signal processing, and data transfer applications.
