72851L10PF application field and working principle

72851L10PF is an integrated First In First Out (FIFO) memory that has been developed by Philips Semiconductor. It is used as an interface between two digital systems or components with different speeds or timing systems. It can also be used to exend the time of execution of instructions in a single processor system. It\'s basically a memory buffer which allows for faster data throughput between units.

Function

The 72851L10PF FIFO memory stores the data sent by an upstream component in an addressable location after which the data can be read out by a downstream component. This allows two components to operate at different speeds without data loss. The FIFO memory is usually configured as a 8-bit or 16-bit unit in which multiple read/write operations can be done. The FIFO memory also provides an Empty or Full status signal which indicates if the FIFO is empty or full. This signal can be used to synchronize the flow of data between the two components.

Applications

The 72851L10PF FIFO memory can be used in a wide variety of applications such as communications, video encoding/decoding, disk controllers and industrial automation. It is commonly used to bridge asynchronous components, buffer data streams and extend processor bus cycles. It also provides a way of interfacing two different serial interfaces as well as allowing two processors to communicate at different speeds. The FIFO memory has also found applications in military and aerospace systems.

Working Principle

The 72851L10PF FIFO memory functions based on the principle of first-in-first-out (FIFO). This means that the data that is sent first enters the memory unit first and is sent out first when data is requested. The FIFO memory stores the data in an addressable location which is then retrieved and removed from the buffer via a read operation.

The 72851L10PF FIFO memory incorporates dual-port memory which allows for simultaneous data transfer. Data can be written to and/or read from the FIFO asynchronously, synchronously or through a combination of both. The FIFO memory also includes an interrupt and status flag which indicates when the FIFO is empty, full or partially filled.

Conclusion

The 72851L10PF FIFO memory is a highly versatile component that can be used in a wide range of systems. It is used to bridge asynchronous components, buffer data streams, extend processor bus cycles. The FIFO memory incorporates dual-port memory and additional features such as an interrupt and status flag. It is also commonly used in military and aerospace systems.
