72V293L15PF8

FIFOs Memory Overview

The 72V293L15PF8 is a synchronous FIFO memory device manufactured by Renesas Electronics. It offers a storage capacity of 1.125 Mbit, organized as 64K x 18 or 128K x 9 bits. The component operates with a maximum clock frequency of 66.7 MHz and features an access time of 10 ns. It functions on a supply voltage range of 3.15 V to 3.45 V, with a maximum power consumption of 35 mA. The device utilizes a unidirectional data bus and is housed in an 80-LQFP package.

FIFOs Memory Feature Summary

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

FIFOs Memory Applications

• Network interface buffering
• Data acquisition systems
• High-speed digital signal processing interfaces

FIFOs Memory Procurement Notes

Verify the obsolete status and end-of-life notices before procurement planning. Confirm that the 80-LQFP package dimensions match the target PCB footprint. Ensure compatibility with the required 3.3V logic levels and check for moisture sensitivity handling requirements during assembly.

FIFOs Memory Selection Notes

Select this component when a 128K x 9 or 64K x 18 synchronous FIFO is required with 10 ns access speed. It is suitable for designs needing independent read/write clocks and programmable status flags. Verify that the 80-pin TQFP/LQFP package fits the available board space and thermal constraints.

FIFOs Memory Part Context

This part belongs to the Renesas SuperSync II family of synchronous FIFOs. It serves as a functional replacement for older 5V devices like the 72291, offering lower power consumption while maintaining similar performance characteristics. The series is designed for high-speed data buffering applications requiring reliable first-word fall-through capabilities.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible alternatives within the 72V2x1 or IDT72V21x1 families. Verify if newer generations from Renesas offer improved availability or enhanced features while maintaining electrical compatibility.
