At the intersection of computing, logic and memory, FIFOs are an important development in memory technology. The SN74ACT7882-20FN is an advanced FIFO (first-in-first-out) memory IC that integrates logic and memory, providing higher memory storage efficiency than traditional memory architectures. This FIFO memory IC is an ideal choice for applications demanding reliable, high-density memory storage, such as communication and computing.

Overview

The SN74ACT7882-20FN is a high-density FIFO memory integrated circuit manufactured by Texas Instruments. It consists of eight 512-byte FIFOs and a single write protection mechanism. The FIFOs are organized as a matrix with one read port and one write port for each FIFO. Its main function is to store data sequentially, implementing the classic FIFO concept. SN74ACT7882-20FN also provides an 8-bit wide data path, supports full memory control and provides two acknowledge signals, Ready and Empty.

Features and Benefits

The key features of SN74ACT7882-20FN include:

• Integrated 8 x 512-byte FIFO memory
• Single write protect function
• 8-bit data path
• Two acknowledge signals, Ready and Empty
• High storage density
• Operates at a wide range of temperatures (-40°C to +85°C)
• Low power consumption

The key benefits of the SN74ACT7882-20FN include:

• Reliable and efficient data storage
• Simple to use and operate
• Suitable for high-frequency computing
• Minimal power consumption

Applications

The SN74ACT7882-20FN is suitable for a variety of applications, such as:

• High-rate digital signal processing (DSP) operations
• High-speed image storage
• Communications equipment
• Industrial automation

Working Principle

The SN74ACT7882-20FN uses an 8-bit data path, which allows it to transmit up to 8-bits of data at a time. Data is written to one of the eight FIFOs on the chip and read from the same FIFO. During access, the data is transferred in a first-in-first-out (FIFO) order with the oldest data being read first and the newest data being read last.

The SN74ACT7882-20FN also features two integrity bits, Ready and Empty, which enable it to report its current state. The Ready bit is active when data is present in one of the eight FIFOs, while the Empty bit is active when all the FIFOs are empty. The Ready and Empty bits are used to signal the available data in the FIFO and control the FIFO access.

Conclusion

The SN74ACT7882-20FN makes a valuable addition to the family of FIFO memory integrated circuits. Its high storage density, low power consumption and reliable operation make it an ideal choice for a wide range of computing applications, from industrial automation to high-speed image storage.
