72801L10PF

FIFOs Memory Overview

The Renesas 72801L10PF is a dual synchronous FIFO memory device featuring two independent 256 x 9 bit buffers within a single package. It supports simultaneous read and write operations using independent clocks or a single shared clock. The component operates on a 4.5 V to 5.5 V supply voltage with a maximum access time of 10 ns. It utilizes a 64-pin TQFP surface-mount package and includes programmable status flags for buffer management.

FIFOs Memory Feature Summary

• Dual independent FIFO structures allowing separate data buffering paths
• Supports asynchronous read and write operations via independent clocks
• Programmable empty, full, and half-full status flags
• Capable of bidirectional data transfer configurations

FIFOs Memory Applications

• Multiprocessing systems requiring rate matching between processors
• Data communications interfaces needing parity bit handling
• Buffering applications in high-speed digital signal processing
• Network equipment requiring temporary data storage during congestion

FIFOs Memory Procurement Notes

Verify the specific suffix 'L10' against official Renesas documentation to confirm the 10 ns speed grade and electrical characteristics. Confirm the 'P' package designation matches the required 64-pin TQFP form factor. Check current product lifecycle status as older FIFO families may be discontinued or subject to last-time buy notices. Ensure compatibility with existing system voltage levels before integration.

FIFOs Memory Selection Notes

Select this component when dual independent buffering is required without external logic overhead. Compare against single FIFO alternatives if only one data path is needed. Verify that the 10 ns access time meets the system's timing requirements. Consider the 64-pin footprint constraints during PCB layout planning. Evaluate power consumption specifications against available thermal dissipation capabilities in the target enclosure.

FIFOs Memory Part Context

This part belongs to the Renesas 728xxL series of synchronous FIFO memories. These devices are designed for high-performance data buffering in complex digital systems. The series offers various depth and width configurations to suit different memory requirements. They are commonly used in telecommunications and industrial control applications where reliable data integrity is critical.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible replacements within the same Renesas family. Verify functional equivalence regarding clock independence and flag outputs. Review any updated datasheets for changes in electrical parameters or package dimensions.
