FIFOs (First-In-First-Out memories) are memories in which the first data written in is the first data read out, chronologically. A common type of FIFO is the 72V271LA15TF8, which is a 15-bit FIFO memory used in a variety of applications such as high-speed data acquisition and process control.
The 72V271LA15TF8 differs from other FIFOs in that it has an additional port, B, to allow multiple ports to access the FIFO concurrently. This makes the memory especially useful in applications where multiple components may need access to the data, for example, in data acquisition systems. It is this versatility that has made the 72V271LA15TF8 a popular choice for many applications.
The 72V271LA15TF8 is also capable of functioning in full- or half-duplex operation, depending on the application. In half-duplex operation, the FIFO operates as a first-in-first-out buffer where data is in the FIFO when it is read out. In full-duplex operation, data is written into the FIFO at the same time it is read out, allowing simultaneous transmitting and receiving of data over a network.
The 72V271LA15TF8 is also capable of effectively preventing data overflows and underflows. When an overflow or underflow occurs, the FIFO is capable of generating an interrupt signal, indicating which type of event has occurred. This allows the system to take corrective action and reliably continue to function.
The working principle of the 72V271LA15TF8 is straightforward. It consists of two linked SRAMs (static random access memories), one for the FIFO (the write buffer) and one as a data buffer. Data written into the FIFO is stored in the write buffer and can then be accessed by either port A or B. When data is read out of the FIFO, it is stored in the data buffer, which is then accessed by the appropriate port.
In summary, the 72V271LA15TF8 is a 15-bit FIFO memory used in a wide range of applications, from data acquisition systems to process control. It is capable of full- or half-duplex operation and can generate interrupt signals when an overflow or underflow occurs. Its working principle is based on two linked SRAMs, one for the FIFO and one for the data buffer, allowing data to be written into the FIFO and read out.
