FIFOs, or First In, First Out queues, are dedicated memory devices designed to store and retrieve data using a queueing protocol, rather than a random access approach. The IDT7200L35SO8 is a widely used FIFO device that packs a powerful feature set into a low voltage / low power CMOS package. This article will discuss the application field and working principle of this device in detail.

Application Field

The IDT7200L35SO8 is adapted for a variety of applications, including data acquisition, telecommunications, computer peripherals, instrumentation, and industrial control systems. Additionally, due to its low power consumption and high integration, it is optimal for point-of-sale (POS) systems, set-top box (STB), video game consoles, and other consumer products. The device is extremely flexible; it can be used with a variety of logic families, such as TTL, ECL, HSTL/LVTTL, 2.5V, 1.8V, and 3.3V. And, it is available in 8-, 16-, and 32K FIFO capacities.

Working Principle

The IDT7200L35SO8 operates according to the basic principles of FIFO queues. It stores data items in a queue, and retrieves them in the same order in which they were received. The device contains a data buffer, address pointer, counter, control logic, and support circuitry. The data buffer stores the data in first-in, first-out order. The address pointer points to the location where the data is written or read from the buffer. The counter keeps track of the number of data items stored in the buffer. The control logic controls the data transfers between the buffer and external devices, as well as the status of the buffer\'s data content. The support circuitry provides the necessary enabling signals to indicate the state of the FIFO.

Advanced Features

The IDT7200L35SO8 FIFO device also contains advanced features that sets it apart from other FIFO devices. For instance, it is designed to operate with both busses and single-ended logic levels. It is also designed with synchronization technologies, such as programmable inputs, which ensure that aligned data result in, and out of, the device. In addition, the device is designed with built-in error checking and diagnostics, which can be used to detect any erroneous data either entering or leaving the device. Last but not least, it is designed to be fully programmable, allowing the user to adjust the device\'s operating frequency, transaction size, and control signals.

In summary, the IDT7200L35SO8 FIFO device is a popular device for a variety of applications, due to its low power consumption, high integration, and advanced features. It is capable of storing and retrieving data in first-in, first-out order, and contains a data buffer, address pointer, counter, control logic, and support circuitry. Furthermore, it includes more advanced features, such as synchronization technologies, programmable inputs, and built-in error checking and diagnostics. All-in-all, it is a very capable and versatile FIFO device.
