FIFOs (First In-First Out) memory devices provide temporary storage for data between two devices, such as a processor and a DRAM (Dynamic Random Access Memory). While RAM devices store data for permanent use, FIFOs are primarily used for buffering or receiving data from slower external devices, such as from sensors or from digital-to-analog converters. In computing, FIFOs are commonly referred to as queues, which are similar in nature to the linear stacks used in traditional stack-based architectures.

The 7201LA15JGI8 is one of many FIFOs on the market that comes in a variety of sizes and speeds to suit a broad array of application needs. The 7201LA15JGI8 is a fast, low power, 8 bit, CMOS SRAM FIFO designed for applications including meters, data communication systems, and medical equipment. Its high speed throughput of 15 Mbps and its low power consumption of only 3 µW make it an ideal choice for cost-sensitive applications in high-density, low-power systems.

7201LA15JGI8 Application Field

The 7201LA15JGI8 can be used for a broad range of applications in both commercial and industrial settings. Common applications include:

• Data communication systems
• Data acquisition systems
• Multi-sensor technology systems
• Medical equipment
• Industrial automation
• High speed meters
• Embedded systems

The 7201LA15JGI8 can also be used in industrial control applications, as it features a fast 15 Mbps throughput rate and low power consumption. Additionally, it is also suited for data acquisition and logging applications, providing a reliable and versatile means of storing data.

7201LA15JGI8 Working Principle

The 7201LA15JGI8 operates on the FIFO (First In-First Out) principle. This means that once data is written to the FIFO, it is read in the first in-first out order. The 7201LA15JGI8 has two memory blocks, which are capable of storing 256 8 bit instructions. The external memory block, labelled A, can store up to 256 instructions and the internal memory block, labelled B, can store up to another 256 instructions, resulting in a total capacity of 512 instructions.

The 7201LA15JGI8 also has a data buffer to store instructions while they are being processed. Additionally, a number of programmable flags are used to signal when the FIFO is full, empty, or at the halfway point, allowing for dynamic control of data flow.

All instructions are handled according to the FIFO principle, looping from the beginning of the memory back to the start. This means that if the internal memory is full, the instruction will move onto the external memory. When the internal memory is emptied again, the instruction is moved back to the start of the internal memory.

Conclusion

The 7201LA15JGI8 is a reliable and versatile FIFO memory device, featuring a high speed throughput of 15 Mb/s and low power consumption of only 3µW. Its low cost and fast response time make it ideal for cost-sensitive applications in data communications, data acquisition, medical, industrial automation, and other high density and low power systems. Its adherence to the FIFO principle facilitates the quick and efficient storage and retrieval of data, allowing it to adapt to changing demands and find a place in a wide array of applications.
