FIFOs (First In First Out) memories are one type of logic device that are used to store data in a memory buffer and transfer it to a destination. They are commonly used in bulk data transfer between two processes or two memories. The 72V811L10TF8 is an example of an FIFO device manufactured by NEC that has an on-chip RAM capacity of 1024x16 bits and can be used to move data between two processes with different data rates.

Application Fields

The 72V811L10TF8 is typically used to link relatively slow source memory devices and fast destination memory devices, such as when reading data from a disc drive and writing it to a hard drive. In this case, the device acts as an intermediate storage buffer between the two, allowing the data to be temporarily stored so that the transfer rate from the slower device does not affect the speed of the faster device.

The 72V811L10TF8 is also used in applications where data needs to be transferred between two processors or two memories with different data rates. The device can be used to synchronize different-speed memories, or to allow a low-speed processor to catch up to a fast-speed processor by temporarily storing the data that needs to be transferred.

Working Principle

The 72V811L10TF8 works by storing data in its on-chip RAM and then transferring it to its destination when needed. The device has two modes of operation: read mode, where data is read from the RAM and transferred to the destination; and write mode, where data is written to the RAM from the source. Data can be written and read in either direction, allowing either processor or memory to act as the source or the destination.

The 72V811L10TF8 supports data transfers at speeds up to 100 Mbps, and has both synchronous and asynchronous read/write operations. The device provides a configurable trigger point for read/write operations, allowing different sizes of data to be read or written as needed. The device also supports a buffer full and buffer empty feature, allowing the device to pause or resume transfers as needed.

Conclusion

The 72V811L10TF8 is a FIFO memory device manufactured by NEC, which is used for transferring data between two relatively slow or fast memory devices or processors. The device has an on-chip RAM capacity of 1024x16 bits, and supports data transfers at speeds up to 100 Mbps. The device supports synchronous and asynchronous read/write operations, and has a configurable trigger point for read/write operations. It also has a buffer full and buffer empty feature, allowing the device to pause or resume transfers as needed.
