Logic - FIFOs Memory

The 72V3640L6PFG8 is a memory that falls under the category of a Logic - FIFOs Memory. It is a dual-ported static random access memory (SRAM) that operates in a lock-step configuration. Its main purpose is the maintenance of shared memory between two or more processers or programmable logic controllers. This device is capable of accessing data for both reading and writing operations.

Features

The 72V3640L6PFG8 features an 8-bit wide data path and an address space of 4096 bytes. It is composed of two data banks (A and B) with a total memory size of 256K bits. The 72V3640L6PFG8 also features a high clock rate of 72MHz and low power consumption of 1.2V.

In order to ensure that a memory operation is properly executed, the 72V3640L6PFG8 contains various control signals such as request, grant, match, and reset. It also has various output pins for the status of memory operations and the outputs for the contents of the data banks. The 72V3640L6PFG8 also contains a simple storage controller, which allows the user to easily access the content of the memory.

Applications

This Logic – FIFOs Memory device has a large range of applications. It can be used in many embedded applications such as industrial control systems, digital signal processing and real-time systems where having a fast and reliable memory is required. The 72V3640L6PFG8 is also often used in embedded systems which are exposed to a high risk of power failure. This device is specifically designed to sustain such environmental conditions.

Other applications of the 72V3640L6PFG8 include audio/video controllers, aerospace and telecommunications systems, computer peripherals and multi-processor systems. The 72V3640L6PFG8 is also used in distributed data processing, embedded systems and in real-time systems.

Working Principle

The 72V3640L6PFG8 is a dual-ported SRAM that works in a lock-step configuration. It is composed of two identical memory banks A and B which are synchronized and accessed by two memory controllers concurrently. Both the memory banks and controllers are connected to each other by internal and external address and data buses.

The 72V3640L6PFG8 controller requests and grants access to the memory banks at required intervals by controlling certain signals such as match, reset and grant. When the controller grants access, it then reads and stores the data in each memory bank separately. Once the data is stored in each memory bank, it is also verified by a matching algorithm.

When the matching algorithm finds a match, the device is triggered to output the data. This output is then used by the controller to perform any kind of logic operation with the data in hand. The 72V3640L6PFG8 controller also periodically triggers certain operations like self-refresh or power down, based on the status of the control signals.

Conclusion

The 72V3640L6PFG8 is a versatile memory device that falls in the category of Logic - FIFOs Memory. Its ability to access data quickly, maintain shared memory between multiple processors and low power consumption makes it an ideal choice for various embedded and real-time applications. It also has a working principle that is relatively simple yet efficient.
