Logic FIFO memory is a type of memory used to store data that needs to be processed in order and at intervals. FIFO stands for first-in, first-out and describes the buffer’s method of storing and retrieving data – the oldest data stored is the first data that is retrieved. The 72V811L15PF8 is a particular type of FIFO memory and its application field and working principle is discussed in further detail below.

Application

The 72V811L15PF8 FIFO is a programmable FIFO designed to store and retrieve data of a particular size. It comes in a 14-pin DWCC package and is ideal for applications where maximum available depth and data integrity is needed. Some applications include: data acquisition system buffering, sequential image scanning and image processing applications, medical imaging and computing, audio sensing and processing applications, line buffering, and communications systems.

Working Principle

The 72V811L15PF8 is a dual-port FIFO memory which allows for two different processes to access the memory simultaneously. It offers asynchronous read and write capabilities with three control signals: write enable (WE), read enable (RE), and reset (RST). Data is written into the FIFO based on write enable and read out of the FIFO through read enable signals. The FIFO will output data in the same order in which it is written, providing a first-in, first-out storage sequence.

Upon powering, the FIFO will go through a self-test which ensures that all memory locations can be written to and read from. The FIFO can be configured by mode selection pin (WE/OE) to operate in either write access mode or read access mode. In write access mode, data is written into the FIFO using the write enable inputs. In read access mode, data is read out of the FIFO using the read enable inputs. In both cases, once the FIFO is full, no more data can be loaded until the FIFO is emptied. The FIFO also includes two flag outputs: empty flag (EF) and full flag (FF). These flags can be used to monitor the state of the FIFO and the system can take appropriate action when the FIFO is either empty or full.

Conclusion

The 72V811L15PF8 dual-port FIFO memory is a versatile memory device that can be used in many different applications. Its ability to store and retrieve data in a first-in, first-out sequence makes it ideal for applications that need to store and process data in a precise order. In addition, the programmable configuration options allow users to tailor the FIFO’s operation to specific needs and applications. The 72V811L15PF8 is an ideal choice for applications that require a large amount of data storage, precise data ordering, and reliable performance.
