72V273L7-5BC Logic - FIFOs Memory

FIFOs (First In First Out) memories are widely used in the world of computing, and the 72V273L7-5BC is no exception. This FIFOs memory device is designed to store multiple data elements in a first-in-first-out (FIFO) format, allowing efficient data transfer between two asynchronous signals. This article explains the application fields and working principle of 72V273L7-5BC.

Application fields

The 72V273L7-5BC is built for applications where reliable FIFO data storage and retrieval is required. It is most commonly used in data communications and computer memory applications such as modems, NIC (network interface controllers), DMA controllers and various computer memories. In addition to these applications, the 72V273L7-5BC is also commonly used to bridge speed-differences between two asynchronous sources. This makes it suitable for embedding into a wide range of applications where data transfer between two asynchronous signals is required. The 72V273L7-5BC also features simplified interface and high performance, making it an attractive choice for many embedded and system-level designs.

Working principle

The 72V273L7-5BC works by utilizing a FIFO memory block that is designed to store user-defined data elements in a first-in-first-out format. The device takes an asynchronous address and data bus as inputs, allowing data to be written into or read from the device. When data is written into the 72V273L7-5BC, a pointer is incremented in order to point to the next empty position in the memory block, allowing for efficient and reliable data storage. When data is read from the 72V273L7-5BC, the pointer points to the oldest data element in the memory block, and a read operation will decrement the pointer in order to point to the next oldest data element in the memory block. This process is repeated until all data elements have been read, and the 72V273L7-5BC ensures that no data is lost in the read/write process.

Conclusion

The 72V273L7-5BC logic - FIFOs memory is designed for reliable FIFO data storage and retrieval, making it well-suited for applications such as data communications and PC memory systems. It is also capable of bridging between two asynchronous sources, making it a popular choice within embedded and system-level designs. This device operates on a simple principle, using a pointer to indicate where data should be written to or read from in its FIFO memory block.
