The 7204L15J is a FIFO memory that provides a wide range of uses for a variety of applications, from sequencing video data to providing communication flow control. It is made up of 16k words of 15 bits wide, from which both read and write operations can be achieved. The 7204L15J FIFO memory operates in an asynchronous mode, relying on the FIFO’s flags to determine conditions for read, write and empty. This keeps it from being resource-hungry, and provides a whole other layer of control to those who use it.

Application field

FIFO (First in, first out) memory designs are popular in a wide range of applications. The 7204L15J can provide efficient solutions to data protection and management, communication control, storage and delivery in applications such as broadcasting and surveillance, medical imaging, industrial automation, robotics, data acquisition and remote monitoring. The 7204L15J is also well suited for custom applications that require configurable operation, multiple control ports and software-controlled functions. It is able to provide robust and reliable operation in environments where power is prone to fluctuate, and can ensure data integrity in cases where communication and control systems are large, complex and needs to be separated from each other.

Working Principle

When one writes to the FIFO memory and the other reads from it, the 7204L15J FIFO can constantly monitor the system performance by waiting for a free location in the write buffer, or detecting no-space conditions and waiting for more space to become available in the buffer for write access. This method of operation provides a flow control mechanism that ensures that no data corruption takes place in either the read or write operations. In this way, the 7204L15J FIFO can minimize the possibility of data losses and delays when transitioning between two different memory banks or locations.

Writing to the 7204L15J FIFO is done by confirming the write flag and applying data to the write bus. Then, the read counter updates the address pointer to the next empty entry in the FIFO. To read from the 7204L15J FIFO, the read flag is confirmed and the read address is forwarded to the read bus. After confirming the read flag, the read address is forwarded to the read bus. This process continually relocates the read pointer to continue read operations. The 7204L15J FIFO also provides empty flags and full flags, which can be used to detect read and write conditions.

In summary, the 7204L15J is a powerful FIFO memory for use in involved and fast paced applications. Designed for quick access of sequenced data, it works great for streaming and transferring data, especially over long distances. Furthermore, the 7204L15J’s flags and read/write operation arrangement provide an efficient control and fast response times, making this piece of memory perfect for applications that require maximum performance and stability. Thus, the 7204L15J becomes an ideal companion for a wide range of applications, where it can deliver robust and reliable performance, without being resource-intensive.
