72851L10PF

FIFOs Memory Overview

The Renesas 72851L10PF is a synchronous FIFO memory device offering 144K bits of storage organized as 8K words by 9 bits. It operates at a maximum clock frequency of 100 MHz with an access time of 6.5 ns. The component functions as a dual synchronous FIFO, effectively combining two independent 72251 FIFO units within a single package. It requires a 5.0 V power supply and is housed in a 64-TQFP (14x14) surface-mount package.

FIFOs Memory Feature Summary

• Dual synchronous architecture providing two independent FIFO channels in one package
• High-speed data transfer capability supporting up to 100 MHz clock rates
• Standard 5.0 V logic operation for compatibility with common digital systems

FIFOs Memory Applications

• Data buffering between asynchronous system domains
• Interface bridging in high-speed digital communication links
• Temporary storage in embedded processing architectures

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm package integrity and pin alignment upon receipt. Check for moisture sensitivity indicators if stored improperly. Ensure replacement parts match the original electrical specifications and pinout configuration to maintain system compatibility.

FIFOs Memory Selection Notes

Select this component when dual independent FIFO channels are required in a compact footprint. The 8K x 9 organization suits applications needing moderate depth with 9-bit data paths. Verify that the 5.0 V operating voltage aligns with the target system's logic levels. Consider the 64-TQFP package constraints for PCB layout and thermal management requirements.

FIFOs Memory Part Context

This part belongs to the Renesas 72851L series of synchronous FIFO memories. It is functionally equivalent to integrating two separate 72251 FIFO devices into a single integrated circuit. The series provides reliable data buffering solutions for digital systems requiring synchronized read and write operations with distinct clock domains.
