72V271LA15PFGI

FIFOs Memory Overview

The 72V271LA15PFGI is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 288K bits, organized as 32K words by 9 bits. The component supports a data rate of 66.7MHz with an access time of 10ns. It operates on a single 3V to 3.6V power supply and draws a maximum supply current of 55mA. The device is housed in a 64-LQFP package with dimensions of 14x14mm and functions within an industrial temperature range of -40°C to +85°C.

FIFOs Memory Feature Summary

• Supports independent read and write clocks for simultaneous operations
• Features fixed, low first word data latency time
• Includes programmable Almost-Empty and Almost-Full flags
• Enables retransmit operation with fixed latency

FIFOs Memory Applications

• High-speed data buffering between asynchronous clock domains
• Data acquisition systems requiring precise timing control
• Telecommunications equipment interface buffering
• Industrial automation signal processing chains

FIFOs Memory Procurement Notes

Verify the specific suffix PFGI against official Renesas documentation to confirm the lead-free status and tape-and-reel packaging configuration. Ensure compatibility with existing board layouts regarding the 64-TQFP footprint. Confirm that the 3.3V operating voltage aligns with the target system's power rails before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when a 32K x 9 depth is required with 10ns performance. It is suitable for designs needing independent clock domains and programmable status flags. Consider the 64-pin LQFP package constraints for PCB space. Verify that the 55mA current draw fits within the system's thermal and power budget requirements.

FIFOs Memory Part Context

This part belongs to the 72V271 SuperSync FIFO family, designed for high-performance applications. It replaces older 5V devices like the 72291 series while maintaining functional compatibility. The 72V271LA variant specifically targets 3.3V systems with optimized power consumption characteristics compared to previous generations.
