Introduction

The 7283L15PA is a logic FIFO memory which utilizes a dual-port RAM technology to provide a low-cost, very high-performance storage for multiple applications. It is used in memory designs for both digital and analog circuitry, as well as for applications requiring highly protected and tightly controlled memory functions.

Memory Design

The 7283L15PA features a low data size of 16 bits, but it provides a great deal of versatility in sharing and transferring data between applications. It is a two-port, dual-port RAM-based FIFO which allows two applications to simultaneously share data with one another. This type of FIFO has the ability to store multiple words of data and offers multiple modes of control to facilitate data integrity and memory protection, as well as access to stored data in a very efficient manner.

Application Fields

Since the 7283L15PA is such a versatile, high performance memory, it is well suited for many types of applications, such as:• Data acquisition systems• Data logging• Communications systems• Medical devices• Military applications• Robotics• Machine vision• Transportation systems• Networking solutions• Embedded control systems

Working Principle

The 7283L15PA works on an efficient, dual-port RAM technology which is capable of storing multiple words at a time and allows for simultaneous access to and exchange of data between different applications. The device maintains data integrity and memory protection by providing numerous control modes. The 7283L15PA maintains separate write and read pointers which allow it to provide separate access to the write and read registers. This allows for two or more independent applications to access the same memory simultaneously, while still providing the ability to read or write data as needed. The device also features an extra byte of data which is used as a rollover byte which allows multiple applications to wrap around the FIFO memory\'s contents. It also has an input/output (I/O) register which can be used to read or write data from one application to another using interrupt-driven logic. Finally, the device utilizes multiple modes of control for power conservation and data integrity. These control modes are provided for both the read and write portions of the memory and offer the ability to reset the memory, disable write or read functions, enable interrupts, and to configure the device for various operating conditions.

Conclusion

The 7283L15PA is a highly efficient and versatile logic FIFO memory which is suitable for a wide array of applications. It is a dual-port RAM-based device which provides numerous control modes for data integrity and memory protection, as well as seamless access to data between two or more independent applications. The device also features some of the most modern features available, including an input/output register, rollover byte, write and read pointers, and multiple modes of control for power conservation and data integrity. This makes the 7283L15PA an ideal choice for many different applications which require efficient memory access and reliable data integrity.
