Introduction

The IDT72T40118L4BBG is a static memory device used in a wide variety of applications, such as programmable logic devices (PLDs), embedded systems, telecommunications and networking equipment, and medical devices. It is an FIFO (first in, first out) type of memory, which is based on a shallow, four-port RAM (Random Access Memory).

Application field

The IDT72T40118L4BBG is a highly versatile embedded memory device and is suitable in a wide range of applications. Industrial applications include manufacturing, Robotics, Automation, Measurement, Control, Safety and Electronics. The FIFO is also used in communications and networking applications such as Voice Over IP, mobile access, home/business/industrial automation, high-speed routers, and military and aerospace applications.It has also found application in medical electronics, for use in medical imaging devices, such as ultrasound and MRI scanners, medical pumps, infusion systems, and other medical instruments.Due to its speed and reliability, this FIFO has also been implemented into advanced computer systems and AI driven applications.

Working principle

The IDT72T40118L4BBG is a static FIFO (First-In-First-Out) type of memory. It operates by simultaneously reading data from four address ports and writing data in a different order. The four ports are read at the same time, and each of them shows the same data when shifted to a different location. The ports are connected to a control processor that is responsible for reading and writing data in the correct order.The four ports are organized as a 2x2 grid and can send and receive data simultaneously. They are connected together in a ring structure, so that data can be shifted from port to port in a continuous circuit. The data that is read from one port is written to the other three. Each port is associated with an address register and a data register, which are used for storing the data that is sent and received.The data is sent to the FIFO in packets that vary in size, depending on the application. The maximum packet size is 128 bytes.

Conclusion

The IDT72T40118L4BBG FIFO is a static memory device with a wide range of applications. It is based on a four-port RAM and operates by reading data from four address ports and writing in a different order. The four ports are organized as a 2x2 grid and connected together in a ring structure. Data is sent to the FIFO in packets of varying sizes, depending on the application. This device is used in industrial applications, communications and networking, medical electronics and advanced computer systems.
