72815LB15PFI

FIFOs Memory Overview

The 72815LB15PFI is a 4K x 16 dual synchronous FIFO manufactured by Renesas Electronics. It operates at a 15 ns read/write cycle time and supports independent clocking for each FIFO section. The device features separate control and data lines, programmable flags, and high-impedance output states. It is designed for applications requiring large capacity buffering with design flexibility in a small footprint.

FIFOs Memory Feature Summary

• Dual synchronous architecture providing two independent 4K x 16 FIFOs
• Supports single-clock or asynchronous dual-clock operation modes
• Includes programmable Almost-Empty and Almost-Full status flags

FIFOs Memory Applications

• Optical disk controllers
• Local area network (LAN) data buffering
• Interprocessor communication systems

FIFOs Memory Procurement Notes

Verify component authenticity through authorized channels due to potential obsolescence. Confirm package integrity and pin alignment against the TQFP-64 specification. Review datasheet revisions for any parameter updates prior to integration into final designs.

FIFOs Memory Selection Notes

Select this component when dual-channel buffering with independent clock domains is required. Ensure voltage levels match the 5.0V supply requirement. Consider pin compatibility with existing 72241-based designs if migrating from older architectures.

FIFOs Memory Part Context

Part of the 728xx series of dual synchronous FIFOs. Functionally equivalent to two 72241 units in one package. Designed for industrial temperature ranges and high-density memory applications.
