72255LA15PFI8

Overview

The Renesas 72255LA15PFI8 is a synchronous FIFO memory IC with 144K capacity (8K x 18 bits). It operates at 66.7MHz with 10ns access time in a 64-TQFP package. Supply voltage ranges from 3V to 3.6V, drawing max 55mA. Features include unidirectional bus, FWFT support, and programmable flags. Operating temperature spans -40°C to 85°C.

Feature Summary

• Synchronous first-in-first-out memory architecture for high-speed data buffering
• Programmable full/empty flags and status indicators for flow control
• Uni-directional data bus configuration for dedicated input/output paths

Applications

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

Procurement Notes

Verify RoHS compliance status as the component may not meet current environmental standards. Confirm package dimensions match design requirements. Check availability of obsolete stock or qualified alternatives due to discontinuation status. Validate supply chain authenticity for legacy components.

Selection Notes

Select this part for applications requiring 8K x 18 bit synchronous storage. Ensure system voltage aligns with 3V-3.6V range. Consider thermal management for -40°C to 85°C operation. Verify pin compatibility with existing PCB layouts using 64-TQFP footprint.

Part Context

Part of the 72V255LA series super synchronous FIFO family. Shares architectural similarities with IDT72255LA variants. Designed for high-performance memory buffering applications requiring deterministic latency and reliable data integrity in industrial environments.

Replacement Considerations

Consider IDT72255LA15PFI8 as a direct functional substitute. Verify pinout compatibility before substitution. Check updated datasheets for any parameter variations between Renesas and IDT branding.
