72V281L20PF8

FIFOs Memory Overview

The 72V281L20PF8 is a synchronous FIFO memory IC manufactured by Renesas Electronics. It provides a total storage capacity of 576 kilobits, organized as 64K words by 9 bits. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports data transfer rates up to 50 MHz with an access time of 20 ns. It is housed in a 64-pin TQFP package.

FIFOs Memory Feature Summary

• Synchronous first-in-first-out memory architecture for high-speed data buffering
• Supports bidirectional data bus operation for flexible system integration
• Includes programmable status flags for full, empty, and threshold conditions

FIFOs Memory Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between components operating at different clock domains
• Data acquisition systems requiring temporary storage before processing

FIFOs Memory Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against specific project standards. Check moisture sensitivity level handling procedures during assembly. Validate pin compatibility with existing PCB footprints. Review end-of-life notices for long-term supply constraints.

FIFOs Memory Selection Notes

Select this component when a 64Kx9 synchronous FIFO is required. Ensure the design accommodates the 64-TQFP package dimensions. Verify that the 3.3 V logic levels match the system interface. Consider the 20 ns access time relative to the target clock frequency. Evaluate bidirectional bus needs versus unidirectional alternatives.

FIFOs Memory Part Context

This part belongs to the Renesas 72V281 series of synchronous FIFOs. It shares architectural similarities with other members like the 72V281L15PFGI but differs in speed grade and organization. The series is designed for general-purpose memory applications requiring reliable data flow management.
