Top 3 FIFO Manufacturers Worldwide

FIFO stands for “First In- First Out”. It is a type of data storage or memory buffer where the data that enters the memory is the first to be retrieved. It follows the principle that the first data element stored in the buffer will be the first one to be removed. FIFO Memory is used in electronic and computer applications to control the data flow between different system parts when the data rate between the sender and receiver is not matched. This prevents data loss or misordering.

Mouser Electronics offers FIFO memory components from Cypress Semiconductor, IDT (Integrated Device Technology), and Texas Instruments. These companies make FIFO memory ICs (Integrated Circuits) and related components used in electronic systems for data buffering and data flow management. These FIFO memory components are found in various applications, such as data transfer, storage, and control systems.

Key Characteristics of FIFOs

Data Order Preservation: FIFOs keep data items in chronological order, ensuring that the first data item in is the first data item out.

Storage and retrieval: FIFOs comprise storage locations where data is written and read from, which are handled by pointers and control logic.

Flow Control: They enable efficient data flow control, preventing overflows and underflows.

Versatility: FIFOs are utilized in a wide range of industries and applications, from networking equipment to medical devices, to ensure data integrity and reliability.

How does FIFO work?

FIFO is the key electronic component used to govern data flow inside digital systems, particularly when data must be temporarily held and retrieved in an organized manner.

• Data Input: When a digital system generates or receives data, it is stored in the FIFO. This information can take the form of binary data, such as digital signals or binary code.
• Storage: A FIFO is a storage array or memory buffer that has numerous storage locations organized as a queue. Data is written into the FIFO’s storage places one item at a time. The initial data item written into the FIFO is placed in the first accessible storage space, and subsequent data items are stored sequentially.
• Pointer Management: Pointers are used to maintain track of the read and write places within the FIFO. A write pointer indicates where the next data item will be written, whereas a read pointer shows where the following data item will be read.
• Control logic: Control logic circuits control the passage of data within the FIFO. These circuits ensure that data is written to the next available storage place and read from the correct location based on the FIFO sequence.
• Full and Empty Conditions: FIFOs have systems that determine when they are full (no more data can be written) or empty (no more data can be read). These factors aid in the prevention of data overflow and underflow.
• Data Flow Control: External signals or control logic can pause or resume data flow into or out of the FIFO in some applications, providing flow control when data rate mismatches arise between input and output.

Why is FIFO used in semiconductor and automotive electronics?

FIFO, which stands for “First In, First Out,” is a crucial concept and technology used in the automotive semiconductor sector for several important reasons:

• Real-time Data Processing: Real-time data from various sensors, such as cameras, radar, LiDAR, and others, is frequently processed in automotive applications. FIFO buffers help to ensure that data is handled in the order it is received, preserving the information’s chronological integrity. This is especially important for jobs like autonomous driving, where rapid and precise data processing is key for safety and performance.
• Data Synchronisation: Multiple components in an automobile system, such as microcontrollers, sensors, and communication interfaces, must exchange data. FIFOs serve as data buffers, keeping the data flow between various components synchronised. They protect against data loss or corruption by ensuring that data is transported in a structured and orderly fashion.
• Latency Management: To adapt quickly to changing road conditions, automotive systems frequently require low-latency connection and data processing. By queuing data and ensuring that it is processed in a timely manner, FIFOs can assist reduce latency, decreasing delays in important activities.
• Fault Tolerance: Automotive systems must be resistant to faults and interruptions. By temporarily storing data during system disruptions or glitches, FIFOs can provide a level of fault tolerance, preventing data loss and allowing for graceful recovery.
• Memory Management: Memory resources in automotive semiconductor devices are frequently constrained. FIFOs aid memory management by temporarily keeping data before processing or transmitting it, preventing memory overflow, and ensuring that the system functions within its memory restrictions.
• Interfacing with Different Data Rates: Automotive systems may have components that operate at different data rates or in separate clock zones. FIFOs can act as data rate converters, allowing these components to communicate seamlessly by temporarily storing data until it can be synchronized with the receiving end.
• Bursty Data Traffic Buffering: Some automotive applications, such as data logging or diagnostics, may entail bursty data traffic, in which data arrives in irregular bursts. FIFOs can absorb these surges and smooth the data flow, reducing congestion and assuring effective data processing.
