SN74ALVC7803-25DLR Application field and Working Principle

The SN74ALVC7803-25DLR device is a member of the Widebus Logic – FIFOs Memory family of products from Texas Instruments. It is a high-performance FIFO memory that offers high throughput and distributed optimizations to handle peak and edge-case performance requirements. It is ideal for applications that require high-speed, on-chip memory at lower cost points. This device is a 25-bit FIFO with an extended data bus range of 6, 8 and 16 bits for multiple applications.

The SN74ALVC7803-25DLR supports multiple signals, including Bus N (up to 16 bits) and up to 16 I/O Bus signals. It also features an asynchronous BusRst signal, as well as a Fast Reset feature. This device provides a high-speed, distributed interface to each connected Bus by using a distributed routing fabric that provides multiple paths through the core. The distributed routing fabric connects to the I/O buses and Bus Rst inputs to the Bus N logic.

Features and Benefits

• Distributed Bus Routes: It features a distributed routing architecture that provides multiple paths to each connected Bus. This enables higher throughput and improved latency in peak-performance scenarios.
• High-speed I/O: Compressed BusRst provides an I/O bus connection to Bus N logic with up to 16-bit wide I/O. This enables higher throughput than conventional FIFO memories.
• Extended Data Bus Range: The data bus range of 6, 8, and 16 bits provides flexibility for multiple applications.
• Flexible Reset: An asynchronous BusRst signal can reset individual I/O buses or all of them at once.
• Fast Reset: This device features a Fast Reset feature, which permits reset sequences in only a few clock cycles.

Applications

The SN74ALVC7803-25DLR device is an ideal component to use in applications that require high-speed data transmission, such as communications systems, image processing and multimedia. It is also suitable for applications that require large, multiplexed data buses, such as routers and switches.

Working Principle

The SN74ALVC7803-25DLR device works on a principle of FIFO (First In, First Out) memory. When data is written into the memory from one of the I/O buses, the data is stored in the FIFO, and it is read out again in a First In, First Out manner. This is done to provide high throughput performance for applications needing access to large amounts of data.

The BusRst signal used in this device allows a user to reset the entire memory or an individual I/O bus. The Fast Reset feature permits reset sequences in only a few clock cycles. This ensures that the device can be reset quickly and easily, and that data is not lost in the process.

The SN74ALVC7803-25DLR device is a versatile component that is suitable for applications that require fast data transmission and high throughput. It is easy to use and provides the flexibility of multiple bus widths and reset capabilities. It is the ideal choice for many applications needing high-speed FIFO memory.
