72V291L10TFG

FIFOs Memory Overview

The Renesas Electronics Corporation 72V291L10TFG is a SuperSync FIFO memory device with a storage capacity of 64K x 18 bits. It operates on a single 3V to 3.6V power supply and supports data rates up to 100MHz. The component features a 6.5ns access time and is housed in a 64-pin TQFP package. It includes programmable flags for status monitoring and supports depth and width expansion.

FIFOs Memory Feature Summary

• SuperSync architecture with independent read and write clocks
• Programmable Almost-Empty and Almost-Full flags
• Fixed low first word data latency time
• Auto power down capability for minimized standby consumption

FIFOs Memory Applications

• High-speed data buffering in communication systems
• Clock domain crossing interfaces
• Data rate matching between asynchronous components

FIFOs Memory Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status as per manufacturer documentation. Confirm the package type matches the required 64-pin TQFP footprint. Check current lifecycle status as this series may be subject to discontinuation notices. Ensure compatibility with existing system voltage levels within the specified 3V to 3.6V range.

FIFOs Memory Selection Notes

Select this part for applications requiring fixed latency and high-speed synchronous data transfer. Compare against other 72V291 variants based on required access time and bus width. Consider the 64-pin TQFP package constraints for PCB layout. Verify if the 18-bit width meets system data path requirements compared to 9-bit alternatives.

FIFOs Memory Part Context

This component belongs to the Renesas 72V291 SuperSync FIFO family, designed for low-power 3.3V operation. It serves as a functional replacement for older 5V devices like the 72291. The family emphasizes reduced latency and flexible expansion capabilities for complex digital designs.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible replacements within the 72V2x1 series. Verify functional equivalence with IDT72V21x1 SuperSync FIFOs. Consult official discontinuation notices for recommended alternative part numbers.
