72V245L15TFGI8 Application Field and Working Principle

Introduction:

The 72V245L15TFGI8 is a synchronous, dual-port SRAM (Static RAM) control module, designed to interface with FIFOs (First-In First-Out memory queues) within a system. It is designed as a multi-level housing module, made specifically to allow for high speed operation and handling of complex logic functions and FIFOs. This device is best suited to applications where the FIFO data-width is equal or higher than 8 bits.

Application Fields:

The 72V245L15TFGI8 can be used in a variety of applications which require high speed access. Such applications include Ethernet switches, routers, serial and Ethernet network interface cards, storage area network (SAN) bridges, wireless modems, and many other multi-layer applications. The 72V245L15TFGI8 is a good choice for for FIFOs as it supports robust synchronization between the data queues and low latency access. It is further capable of interfacing with systems containing multiple FIFOs and providing a high level of flexibility with regard to memory sizes and communication speeds.

Working Principle:

The 72V245L15TFGI8 is designed to access and control a single FIFO. It will detect when the FIFO is empty, full, or has a specified number of entries, and then make decisions accordingly. Whenever new data is written to the FIFO, a write pointer increments and moves to the next available location. When data is read out of the FIFO, the read pointer increments, removing the oldest data from the FIFO. It features a reliable current-source architecture, allowing it to achieve a throughput of up to 100 MHz without the need for external clocking sources. For each FIFO entry, it provides a separate signaling line pair that indicates the current status of the entry. One line will show the empty status, while the other will show the full status. These two signals together identify the condition of the FIFO entry.

Conclusion:

The 72V245L15TFGI8 is a reliable, efficient, and high speed control module for FIFOs. It can interface with multiple FIFOs, allowing for robust synchronization between the FIFO data queues and low latency access. It provides a reliable current-source architecture allowing for throughputs up to 100 MHz, and also features separate signaling lines for each FIFO entry which can indicate whether the entry is empty or full.
