72815LB10PF8

FIFOs Memory Overview

The Renesas Electronics Corporation 72815LB10PF8 is a dual synchronous FIFO memory device belonging to the 72815L series. It integrates two independent 512 x 18 bit First-In, First-Out buffers within a single package. The component operates with a supply voltage range of 4.5 V to 5.5 V and supports bidirectional data transfer at frequencies up to 100 MHz. It features a 128-pin TQFP (14x20 mm) surface-mount package. Key functional attributes include programmable flags for empty and full states, separate control lines for each FIFO, and support for first-word-fall-through operation.

FIFOs Memory Feature Summary

• Integrates two independent 512 x 18 bit synchronous FIFOs in a single package
• Supports bidirectional data flow with separate control lines for each buffer
• Includes programmable flags indicating empty and full states for both FIFOs
• Enables flexible configurations such as width expansion and priority buffering

FIFOs Memory Applications

• Bidirectional data buffering between asynchronous systems
• Width expansion applications requiring data bus adaptation
• Two-level priority data buffering scenarios
• Data rate matching between high-speed and low-speed interfaces

FIFOs Memory Procurement Notes

This component is officially discontinued by the manufacturer. Verify availability through authorized distributors or secondary market suppliers. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure replacement strategies account for end-of-life constraints and potential lead time variability from non-standard sources.

FIFOs Memory Selection Notes

Select this part when dual independent FIFOs are required without consuming multiple packages. It is suitable for designs needing bidirectional data handling and programmable status flags. Consider the 128-pin TQFP footprint and 5V logic compatibility during integration. Evaluate thermal performance and signal integrity requirements associated with high-frequency synchronous operations.

FIFOs Memory Part Context

The 72815LB10PF8 belongs to the Renesas 72815L family of dual synchronous FIFOs. This series provides high-density memory solutions for complex digital systems. The device replaces discrete FIFO implementations, reducing board space and design complexity. It is designed for industrial temperature ranges and offers robust performance for data-intensive applications.

FIFOs Memory Replacement Considerations

Verify pin-to-pin compatibility with alternative dual FIFO parts. Check if substitute components support identical 512 x 18 organization and bidirectional functionality. Ensure voltage levels and timing parameters match existing design specifications.
