72V291L10TF8

FIFOs Memory Overview

The 72V291L10TF8 is a SuperSync FIFO memory component manufactured by Renesas Electronics. It features a storage capacity of 128K x 9 bits and operates on a 3.3V power supply ranging from 3V to 3.6V. The device supports a read/write cycle time of 10ns with an access time of 6.5ns, achieving a data rate of 100MHz. It utilizes independent read and write clocks for simultaneous operations and includes programmable flags for status monitoring. The component is housed in a 64-pin TQFP package.

FIFOs Memory Feature Summary

• SuperSync architecture enables independent read and write clock domains for simultaneous data transfer.
• Fixed low first word data latency ensures consistent timing performance.
• Programmable Almost-Empty and Almost-Full flags allow precise buffer management.
• Auto power down functionality minimizes standby power consumption.

FIFOs Memory Applications

• Data buffering between asynchronous logic blocks
• Clock domain crossing interfaces
• High-speed data acquisition systems

FIFOs Memory Procurement Notes

Verify the specific suffix 'TF8' against official Renesas documentation to confirm reel packaging and lead-free status. Confirm RoHS compliance details as historical records may vary. Check current lifecycle status as this model may be discontinued or subject to product change notices. Ensure compatibility with existing PCB footprints for the 64-TQFP package before procurement.

FIFOs Memory Selection Notes

Select this component when a 128K x 9 depth is required with 3.3V operation. Compare against the 72V291L20TF8 if slower speeds are acceptable. Verify that the 6.5ns access time meets system timing requirements. Consider the 64-pin TQFP package constraints for board layout. Ensure independent clock inputs are available for the SuperSync feature.

FIFOs Memory Part Context

This part belongs to the 72V291 series of SuperSync FIFOs. It is functionally compatible with the older 5V 72291 but optimized for lower voltage. The series eliminates the Frequency Select pin found in previous generations, simplifying clock configuration. It serves as a direct replacement for legacy IDT designs requiring 3.3V operation.

FIFOs Memory Replacement Considerations

The 72V291L20TF8 offers similar functionality with a 20ns cycle time. Verify pinout compatibility before substitution. Check if the slower speed of alternative models meets application requirements. Confirm that the replacement maintains the same 128K x 9 depth and 3.3V supply range.
