Logic-FIFOs Memory is an important system component used to store data from digital processors and allow data transfer from one digital system to another. The 72V273L10PFI8 is a popular logic-FIFOs Memory application used in many digital system designs. This application and its associated working principles are discussed thoroughly in this article.

Application Field Overview

The 72V273L10PFI8 application is designed as an advanced FIFO memory. It provides 10 bits of dual-port FIFO storage per bit of address. It also provides two independent End-of-Buffer (EOB) and two independent Programmed Pointer (PP) flags which can be used to detect buffer starts and ends. This application has a Simple Load/Store Configuration which enables memory accesses to be completed in two cycles, allowing it to be used in high-speed systems. The 72V273L10PFI8 is primarily used in the computing, telecommunications, and consumer electronics markets.

Working Principle of the 72V273L10PFI8

The 72V273L10PFI8 utilizes a synchronous, first-in-first-out (FIFO) technique for data storage and retrieval. It is designed to provide FIFO operation and to control data transfer between two devices that are operating at different clock speeds. This is accomplished by buffering the data and providing a way to point to and access the data in the buffer. This is done utilizing a simple load/store configuration, allowing each device to access the data in the buffer at its own speed.

The 72V273L10PFI8 consists of four primary components: programmable pointers, the data buffer, dual pointer registers, and a flag register. The programmable pointers are used to select the buffer size and define the location of the data to be stored or retrieved from the buffer. The data buffer is the actual memory area where the data is stored and retrieved from. The dual pointer registers are used for bookkeeping and to track buffer events. Lastly, the flag register is used to track the status of FIFO flags, such as empty and full.

The 72V273L10PFI8 utilizes a write/read sequencing to identify and select data stored in the buffer. To utilize the sequencing, the programmable pointers define the buffer start and end locations. The pointer registers track the current position of data stored in the buffer. The flag register holds logical values that indicate whether or not the buffer is empty or full.

The 72V273L10PFI8 provides means to detect buffer starts and ends via the two independent EOB flags and two independent PP flags. The EOB flag is set when the read pointer reaches the programmable pointer-defined end point and can serve as an indication of buffer size depletion. The PP flag is set when the write pointer reaches the corresponding programmable pointer-defined end point, and can serve as an indication of data overflow.

The 72V273L10PFI8 contains fast access RAM for storing and retrieving data. Data is written to and read from the memory logic simultaneously, allowing multiple accesses to happen without gaps in the data processing. This configuration offers superior data throughput performance compared to traditional asynchronous FIFO memories.

Furthermore, the 72V273L10PFI8 has a modular design that can be easily customized and scaled in order to meet various application needs. This allows designers to create their own custom memory designs that can be implemented quickly and easily.

In summary, the 72V273L10PFI8 is a logic-FIFOs memory application offering fast access RAM for storing and retrieving digital data from multiple devices. It provides 10 bits of dual-port FIFO storage and two independent EOB and two independent PP flags for buffer start/end detection. It is designed to provide fast data transfer between two devices that are operating at different clock speeds. It has a highly modular design, making it easy to customize and scale for various application needs.
