Logic - FIFOs Memory: 7281L20PA Application Field and Working Principle

A FIFO (First-In-First-Out) logic element is a type of Memory that stores digital data as it’s being manipulated. The 7281L20PA is an example of such a logic element. It is a static, dual-ported random-access memory (RAM) that has two independent ports to read and write data. This allows data to be stored and manipulated without being overwritten, while also providing the ability to perform concurrent read and write operations across both ports.

7281L20PA Operating Environment

The 7281L20PA operates in environments that have a frequency of 6.5 to 12MHz. It is designed to operate with a memory size of 28k-bits (2048 x 14) and is rated for operation in temperatures ranging from 0°C to 70°C. The 7281L20PA is also designed with an output current of 4mA per pin, allowing it to output large amounts of data without the need for additional current boosters.

How The 7281L20PA Operates

The 7281L20PA’s main purpose is to perform FIFO memory operations between ports A and B. This is done by sending data into port A, which is stored in the RAM, and then read out of port B. There are two input registers (IR1 and IR2) and two output registers (OR1 and OR2) that are used to store data entering and exiting the RAM.

Data is written into port A via IR1 and is stored in the RAM. It is then read out of port B via OR2. Data is written into port B via IR2 and is stored in the RAM. It is then read out of port A via OR1. The 7281L20PA is designed to allow concurrent read and write operations to both ports in order to optimize the data throughput and maintain data integrity.

The 7281L20PA also comes with two status registers (SR1 and SR2). These registers track data movement between the RAM and ports A and B. This allows the user to keep track of when data has been read and written, and when there are empty or full conditions at either port.

7281L20PA Application Fields

The 7281L20PA FIFO logic element is used in a variety of applications, such as digital signal processing, wireless communication systems, audio and video applications, and robotics. The 7281L20PA has been used in wireless communication systems to store and manipulate data that is being transmitted. In digital signal processing, it has been used to store and manipulate data that is being processed. In audio and video applications, it has been used to store and manipulate audio and video data. In robotics, it has been used to store and manipulate data related to robotic control.

Conclusion

The 7281L20PA FIFO logic element is a type of memory that is designed to store, manipulate, and move data between two ports. It operates in a frequency range of 6.5 to 12MHz, with a memory size of 28k-bits (2048 x 14), and it is rated for temperatures ranging from 0°C to 70°C. It is used in a variety of applications such as digital signal processing, wireless communication systems, audio and video applications, and robotics.
