Introduction

The 72V3690L6PFG is a logic device integrated with FIFOs Memory. It provides a system designers a great range of memory sizes, from 16KB to 256KB. With its easy integration, this logic device can be used in many different kinds of systems, like medical instruments, telecommunications, industrial control and so on.

Application Field

The 72V3690L6PFG can be used in a variety of different fields and applications, such as medical instruments, telecommunication systems and industrial control. With its extensive range of memory sizes, it can serve as a digital buffering system for high data throughput operations in the medical devices, ensuring data consistency and accuracy by buffering incoming data until the device is ready to use it. In telecommunication systems, it can provide data cache to facilitate two-way communication between communication nodes. As for industrial control, the 72V3690L6PFG can be used to store process parameters of machines, allowing easy access to these data points and excellent control of the process.

Working Principle

The 72V3690L6PFG works by utilizing a specialized asynchronous dual-ported FIFO memory technology. This technology uses two separate data buses – one for reading data and the other for writing data – thus allowing multiple processors to interact. Data is written to the memory and read from the memory simultaneously without any need for synchronization. The data are stored in the FIFO and become available when the read operation is initiated. The device also has a reset and Hold feature. When reset and Hold is enabled, the FIFO stops reading out data and resets the pointers. Once reset and Hold is disabled, FIFO resumes the resumed operation and starts sending out data again. Additionally, the 72V3690L6PFG has an interface enable control register. This register provides system designers the ability to separate the FIFO’s read and write pointers in order to improve memory utilization. This also prevents data from being overwritten when the FIFO is full.

Conclusion

The 72V3690L6PFG is a logic device integrated with FIFOs Memory, which provides a great memory size range from 16KB to 256KB. It can be used in many kinds of systems, such as medical instruments, telecommunication systems and industrial control. The device functions by utilizing asynchronous dual-ported FIFO memory technology, which enables two different processors to access the memory simultaneously. Moreover, it has a reset and Hold feature that stops reading out data and reset the pointers, and an interface enable feature that improves memory utilization and prevents data from being overwritten when the FIFO is full.
