72281L20PF Application Field and Working Principle
The 72281L20PF FIFO (first-in, first-out) logic is an ideal solution for designs requiring the need to optimize power, area, and cost. The 72281L20PF is not just a FIFO, but is also an integrated memory solution that can be used with integrated dual port SRAMs and video memories to support larger applications, thereby providing extra data buffering, as well as improved circuit design performance. With its small size and low cost, this FIFO also serves as an invaluable resource for complex memory systems that need to be squeezed into tight size constraints.
The 72281L20PF FIFO is composed of four paired controllers and an address decoder. Its working principle is based on the principle that data or instructions stored in memory units can be transferred for further processing or replication at higher speeds. The design engineer must understand how this logic works and plan the circuitry around an application that needs the functionality to work efficiently. This logic is excellent for many applications where multiple FIFOs are operated in tandem, regardless of their size, to provide a data transmission channel.
Serving a Range of Applications
Several applications, including large data applications such as video boards and memory controller networks, can benefit from the added speed and capacity that the 72281L20PF provides. With its dual-port RAM, the 72281L20PF is capable of storing up to 8K words of data, depending on the model. In addition, this memory can also be used for buffered serialization/deserialization and bidirectional data communication.
The FIFO also offers the ability to transfer data between two different FIFOs, as well as acting as a memory buffer for a serial data stream, while allowing data to be switched between different interfaces. This FIFO can be used to transfer data between different digital data buses, as well as supporting applications such as digital signal processing.
With its very compact design, the 72281L20PF is an ideal choice for embedded systems. These logic elements are ideal for a wide range of applications, including motion control applications, network storage, consumer electronics, and even internet protocol (IP) telephony.
Robust Design
This FIFO offers a robust design featuring an address-controlled write and read support, which allows the user to add a write input that assigns the data’s destination address. This write input will then select the destination where the data will be stored. The FIFO also features a full addressable read/write port, thereby allowing users to read/write data in one cycle without any need for additional cycles.
This FIFO also offers very low power usage, making it a viable option for battery-operated designs. It also supports multiple clock frequencies, allowing it to support multiple applications with varying speed requirements. What’s more, the logic also offers variable delay support, helping to optimize the architecture and improve system performance.
Conclusion
The 72281L20PF FIFO’s simple design, small size, and robust features make it an ideal choice for a wide range of applications that rely on robust and speedy logic schematics. Its low-power consumption, variable delay support, and high-speed access capabilities enable it to provide an ideal buffer for data streaming applications, as well as a reliable address-controlled write/read support for higher-grade memory applications.
