Logic - FIFOs Memory

application field and working principle

72245LB15PFI8 is a logic-based First In First Out (FIFO) memory logic circuit designed for use in consumer electronics and embedded systems. It is capable of storing up to 15x8 bits of data in a 22-bit long dual-port buffer. It allows simultaneous read and write operations from two independent data access ports, which allows for faster read and write speeds and concurrent operation.The 72245LB15PFI8 memory is organized into two main blocks, the main interface and the dual ports. The main user interface is composed of five control lines, which are used to set the desired read and write operations. The two dual ports can be used either separately or together, depending on the application. The circuit is asynchronous, meaning that it does not require the use of a clock signal. Instead, it relies on certain conditions in order to initiate the read and write operations.The main purpose of the 72245LB15PFI8 is to divide and buffer the data stored in the main memory into two independent Dual-Port-RAMs (D-RAMs). This allows for faster read and write operations for both data ports. This is due to the fact that the D-RAMs do not need to constantly communicate with the main memory in order to update its contents. Additionally, this allows for the simultaneous read and write operations of data from both data ports.On the read side, the 72245LB15PFI8 operates in an asynchronous mode. Data is read from the main memory when an enable signal is received. The data is then divided and written into the dual port buffer. The enable signal will then be reset and the next data set can be read from the main memory. On the write side, the 72245LB15PFI8 operates in a synchronous mode. Data is written to both dual ports of the buffer when a valid write enable signal is received. Data is then written to the main memory when a read enable signal is received. The 72245LB15PFI8 is suitable for a wide range of consumer electronics and embedded systems applications. It can be used in applications such as video and audio processing, image processing, data acquisition, communication, and medical electronics. The main advantage of this circuit is its ability to provide simultaneous read and write operation while still being able to divide and buffer the data from the main memory. Additionally, its asynchronous functionality allows for faster read and write operations, which are essential for high-speed applications.
