72271L10PF application field and working principle

72271L10PF is a pipelined FIFO memory module produced by Texas Instruments. It is mainly used in communication systems. It has a variety of applications. In the consumer electronics field, the 72271L10PF can be used for temporary storage of multimedia data, and can also be used for audio and video data Transmission control.

The 72271L10PF-based FIFO memory module uses a single-bit serial interface for data exchange. It is widely used in wireless communications. The module is easy to install, and the data can be read and written in the same bit site, reducing the number of data read and write operations. In addition, the energy consumption is small and the stability is high, which makes it particularly well-suited for the development of communication systems. It is also suitable for applications in PENP networking and high speed automation.

The 72271L10PF FIFO memory module uses two shift registers to store data. The data is exchanged between two registers under the control of the clock. The data can be read out during the exchange period and written in during the exchange period, thereby achieving the FIFO data storage principle. The module has two input ends. When the data exists in one of the two ends, the other can write and read the data. When the data does not exist at either end, the writing and reading operations at the opposite end are stopped to ensure the accuracy of the FIFO data.

During the writing process, the data is written in from the write position, and the write pointer is advanced by an empty data record in the process. At the same time, the read pointer also follows and advances one cycle, so that the write pointer will not overwrite the data of the read pointer. In the same way, the reading operation runs from the read position and the read pointer advances one cycle for each data read, while the write pointer also advances one cycle.

At the same time, two control signals are also used to control the writing and reading, that is, full and empty control signals. When a register is full, it will automatically stop the writing operation. When the register is empty, it will stop the reading process. In this way, when the amount of data in the FIFO is full or empty, the system can be automatically controlled, there by avoiding data overflow or output error problems.
