72815LB15PFI8

Logic - FIFOs Memory

The 72815LB15PFI8 is a dual-ported FIFO (First-In-First-Out) Memory. This device is designed to buffer data between two systems or agents which move data at different speeds or in different directions. It is useful in scenarios where data needs to be stored temporarily and retrieved in a First-In-First-Out format. The device is optimized for low-power operation and for high speed throughput of data.

Application Field

The 72815LB15PFI8 has many applications in asynchronous data storage and retrieval. It can be used to bridge the gap between two separate sub-systems or computing agents that have difference processing speeds or move data in different directions. This device can also be used in communication systems which require a temporary buffer between transmitting and receiving elements.

Data buffer systems which support multiple data streams and require high speed throughput can also benefit from the 72815LB15PFI8. It is also suitable for data acquisition systems which require temporary buffering of incoming data before it is formatted and stored. Other applications include device drivers, video capture, medical imaging, audio signals processing and gaming.

Working Principle

The 72815LB15PFI8 device is composed of two FIFO RAMs, one for each side or port. Each FIFO RAM is divided into a write port, read port, output port, and address pointer. Data is written to the FIFO through the write port, and is read from the FIFO through the read port.

Once data is written to the FIFO through the write port, it is stored in the RAM and the address pointer is incremented. This allows for an ordered storage of the data, and the data that was written first will be the first to be read out through the read port. The data is output to the other port through the output port, allowing for transfer between the two ports.

Both ports feature a bunch of registers which help in operating the FIFO efficiently. These registers allow for set up of the various modes of operation, read and write operations, and control of the overall behavior of the device. Additionally the device features an interrupt output pin, that triggers when specified conditions are met.

Conclusion

The 72815LB15PFI8 is a dual port FIFO memory suitable for scenarios where data needs to be stored temporarily in a FIFO fashion. It is optimized for low-power operation, and for high throughput of data. It has wide range of applications, such as communication systems which require data storage, multiple data stream applications, data acquisition, device drivers, video capture and audio signals processing.
