The IDT7204L35TP is a high-speed CMOS FIFO (First-In, First-Out) memory device manufactured by Renesas Electronics America (formerly IDT). It is designed for applications requiring asynchronous data buffering and rate matching between systems operating at different clock frequencies. This FIFO provides a cost-effective solution for managing data flow in communication, networking, and digital signal processing systems.

Applications

• Data Communications Systems
• Networking Equipment
• Digital Signal Processing (DSP)
• Medical Imaging Systems
• Video Processing Systems
• Industrial Control Systems

Features

• High-speed operation: 35ns access time.
• Asynchronous operation: Allows independent read and write operations.
• Low power CMOS technology: Reduces power consumption.
• Expandable in both width and depth: Allows for increased data storage capacity.
• Output enable control: Facilitates data bus management.
• Half-full flag: Provides an indication when the FIFO is half full.
• Empty and Full flags: Indicate when the FIFO is empty or full, preventing underflow or overflow.
• Retransmit capability: Permits retransmission of data.
• Available in a variety of packages: Offers flexibility in board layout.

Benefits

• Improves system performance by buffering data between asynchronous devices.
• Simplifies system design by handling data rate differences.
• Reduces system cost by minimizing external logic requirements.
• Enhances system reliability by preventing data loss due to underflow or overflow.
• Provides flexibility in system design with expandable architecture.

Additional Details

The IDT7204L35TP typically operates from a 5V power supply. The FIFO depth and width are configurable using external address lines, allowing designers to tailor the memory to their specific application needs. The part utilizes CMOS technology, ensuring low power consumption and high noise immunity. Its asynchronous operation simplifies interfacing to systems with different clock domains. The device's full, empty, and half-full flags simplify system control and prevent data errors. The FIFO is often utilized in applications where high-speed data transfer and buffering are critical, such as in networking equipment, communication systems, and high-performance computing platforms. The availability of a retransmit capability allows for error recovery in certain applications. The specific package will vary depending on the manufacturer and can include options such as DIP (Dual In-Line Package) or surface mount packages.
