72255LA15TF8

Overview

The Renesas Electronics Corporation 72255LA15TF8 is a synchronous FIFO memory device featuring a storage capacity of 144K bits, organized as 8K words by 18 bits. It operates with a maximum data rate of 66.7MHz and an access time of 10ns. The component supports unidirectional bus architecture and functions within a supply voltage range of 4.0V to 5.5V. It is housed in a 64-TQFP (10x10) surface-mount package and is rated for operation across a temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with 10ns access time
• Unidirectional data transfer architecture
• Programmable status flags support

Applications

• High-speed data buffering in digital signal processing systems
• Interface bridging between asynchronous logic domains
• Memory staging in telecommunications equipment

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance requirements against specific project standards, as legacy variants may not meet current environmental directives. Validate package dimensions and pinout compatibility during integration planning. Check for moisture sensitivity handling requirements prior to assembly.

Selection Notes

Select this component for applications requiring reliable synchronous buffering with 18-bit word width. Ensure system power supplies remain stable within the 4.0V to 5.5V operating range. Consider the 64-TQFP package constraints for PCB layout. Evaluate thermal management needs for the specified industrial temperature range.

Part Context

This part belongs to the 72255LA series of SuperSync FIFOs from Renesas. It shares architectural similarities with other members like the 72255LA15PFGI but differs in packaging and orientation. The series is designed for high-performance memory interfacing tasks requiring deterministic latency.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements should be verified against updated Renesas product portfolios or equivalent industry alternatives.
