72V253L7-5PFI

FIFOs Memory Overview

The Renesas Electronics 72V253L7-5PFI is a Super Sync II synchronous FIFO memory device. It features a data bus width of 9 bits or 18 bits, with a storage capacity of 8K x 9 or 4K x 18. The component operates at a maximum clock frequency of 133.3 MHz and has an access time of 5 ns. It functions within a supply voltage range of 3.15 V to 3.45 V. The unit is housed in an 80-pin TQFP package.

FIFOs Memory Feature Summary

• Supports unidirectional data transfer for sequential buffering applications
• Includes programmable flags to indicate full, empty, and half-full states
• Features fast write-first (FWFT) capability for immediate data availability

FIFOs Memory Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between asynchronous logic components
• Data acquisition systems requiring precise timing control

FIFOs Memory Procurement Notes

Verify the specific suffix against official documentation, as variations may exist. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Check for moisture sensitivity levels and recommended reflow profiles prior to assembly. Ensure the source provides valid traceability for quality assurance purposes.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 5 ns access time is required. It is suitable for designs needing 8K x 9 or 4K x 18 depth configurations. Consider the 80-pin TQFP package constraints for PCB layout. Verify that the 3.3V operating voltage aligns with the system power rails.

FIFOs Memory Part Context

This part belongs to the 72V253 series of Super Sync II FIFOs from Renesas Electronics. The series is designed for high-performance memory buffering tasks. It shares architectural similarities with other members like the 72V273 and 72V283, differing primarily in organization and pinout compatibility.

FIFOs Memory Replacement Considerations

The IDT72V253L7-5PFI is listed as an alias for this component. Verify pin-to-pin compatibility before substitution. Ensure the replacement supports the same 3.3V supply and 5 ns access speed requirements.
