72231L15JI8

Introduction

FIFOs, or First In-First Out memory devices, are a type of computer memory that can be used for a variety of applications. The 72231L15JI8 is a specific FIFO device that has a number of important application fields and is used in a variety of systems.

Terminology

FIFO, or First In-First Out, is an acronym for a type of memory device that holds data in a sequential list. Instead of having to store data from individual memory locations as with RAM and ROM, FIFO memory stores data in a continuous chain. When a new piece of data is added to the FIFO, it is placed at the end of the chain and the oldest data is removed first. This type of memory device is very useful in applications requiring the manipulation of streaming data, such as video and audio.

72231L15JI8 Overview

The 72231L15JI8 is a FIFO memory device designed and manufactured by IC manufacturer Analog Devices. The 72231L15JI8 is a 64-bit FIFO memory device with a 16-byte deep data store and a 4-bit data bus. The device is available in two different package types, a 24-pin DIP (dual in-line) and a 16-pin SOIC (surface mounted chip). Both package types are available in either surface mount or through-hole mounting configurations. The device has a maximum data transfer rate of 250 Mb/s and it can sustain a peak data rate of 500 Mb/s. The device also has two separate write and read clocks and can be triggered by either a separate logic signal or a data ready signal.

72231L15JI8 Applications

The 72231L15JI8 is ideal for a wide range of applications due to its high speed, long data store, and multiple bus configurations. The device can be used in video processing equipment to buffer video and audio streams, as well as in radio frequency equipment to store burst data. The device can also be used in memory intensive system designs, such as in telecommunication equipment. The device also has the capability to be configured as either a FIFO or as a first-in-first-out (FIFO) buffer, which allows for more flexibility in system design.

72231L15JI8 Working Principle

The 72231L15JI8 is a device that is set up and operated in a manner similar to RAM and ROM. Data is written into the FIFO device from an external data source, such as from a microprocessor, and it is stored in the device until it is read out by an external device. The FIFO device also has a pair of write and read clocks that are used to control the writing and reading of data. When a data write is initiated, the data is placed at the end of the FIFO and the oldest data is removed and discarded. When a read request is initiated, the oldest data is sent to the external device and the FIFO is updated to the next data value.

Conclusion

The 72231L15JI8 is a FIFO memory device with a wide range of applications and a high data transfer rate. The device can be used in a variety of systems, including video and audio equipment, radio frequency equipment, and memory intensive systems. The working principle of the 72231L15JI8 is similar to other FIFO devices and involves writing data into the device from an external source and reading it out at a later time. The 72231L15JI8 is an ideal choice when high speed and large amounts of data need to be stored in a relatively small form factor.
