72V291L15TF

FIFOs Memory Overview

The 72V291L15TF is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 1.125 Mbit, organized as 128K words by 9 bits. The component supports unidirectional data transfer with a maximum clock frequency of 66.7 MHz and an access time of 10 ns. It operates within a supply voltage range of 3 V to 3.6 V and draws a maximum supply current of 55 mA. The device is housed in a 64-TQFP (10x10) surface-mount package and functions within a commercial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Synchronous operation with single-clock domain control for reliable data buffering
• Programmable status flags including full, empty, and half-full indicators
• First Word Fall Through (FWFT) capability for immediate data availability upon read enable
• Repeater mode support for transparent data passthrough applications

FIFOs Memory Applications

• Buffering data streams between asynchronous system components
• Interface bridging in high-speed digital signal processing systems
• Data buffering in telecommunications equipment
• Temporary storage in embedded controller architectures

FIFOs Memory Procurement Notes

Verify the specific suffix 'TF' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status, as older production runs may differ from current standards. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure the 64-TQFP package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

FIFOs Memory Selection Notes

Select this component when a 128K x 9 depth is required for synchronous buffering applications. The 10 ns access time suits designs operating up to 66.7 MHz. Consider the 3.3 V supply requirement and TQFP-64 package constraints during schematic capture. Evaluate if FWFT functionality aligns with the system's latency requirements compared to standard FIFO modes.

FIFOs Memory Part Context

This part belongs to the Renesas 72V series of SuperSync FIFO memories. The series is characterized by high-speed operation and flexible configuration options. The 72V291 variant specifically targets applications requiring moderate depth with wide data paths. It represents a legacy component within the broader Renesas memory portfolio, often used in established industrial and communication designs.
