72V271LA15TFI

FIFOs Memory Overview

The Renesas 72V271LA15TFI is a synchronous FIFO memory device with a capacity of 288K bits, organized as 32K words by 9 bits. It operates on a single 3.3V supply voltage and supports data rates up to 66.7MHz with a 10ns access time. The component utilizes a 64-pin LQFP package and features uni-directional bus architecture. It includes programmable flags for full/empty status and supports First-Word-Fall-Through functionality.

FIFOs Memory Feature Summary

• Synchronous operation with high-speed data transfer capabilities
• Programmable status flags for buffer management
• First-Word-Fall-Through support for low latency
• Uni-directional data bus architecture

FIFOs Memory Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic domains
• Data acquisition system temporary storage

FIFOs Memory Procurement Notes

Verify the exact suffix designation (e.g., TF vs TFI) against the manufacturer datasheet, as variations may indicate different temperature ranges or packaging types. Confirm RoHS compliance status directly with the supplier, as legacy parts often have specific environmental declarations. Ensure the source document explicitly lists the 72V271LA15TFI part number to avoid confusion with functionally similar variants like the 72V271LA15TF8.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 32K x 9 depth is required for 3.3V logic interfaces. The 10ns access time suits applications needing moderate speed without the complexity of dual-port RAM. Verify that the 64-pin LQFP footprint fits the PCB layout constraints. Consider the uni-directional nature of the bus if bidirectional data flow is not needed.

FIFOs Memory Part Context

This part belongs to the Renesas 72V271 SuperSync FIFO family, designed for high-performance buffering. The LA15 variant specifically targets 3.3V applications, offering lower power consumption compared to older 5V counterparts. It serves as a bridge component in digital signal processing chains where data rate matching between subsystems is critical.

FIFOs Memory Replacement Considerations

The 72V271LA15TF8 is a functionally compatible version available in tape-and-reel packaging. Check datasheets for pinout compatibility and electrical parameter equivalence before substitution.
