72T1885L5BB

FIFOs Memory Overview

The Renesas 72T1885L5BB is a First-In-First-Out (FIFO) memory component manufactured by Renesas Electronics. It features a storage capacity of 16K x 18 bits or 32K x 9 bits. The device operates within a supply voltage range of 2.375 V to 2.625 V, with maximum and minimum limits of 2.625 V and 2.375 V respectively. It is housed in a PBGA-144 package. The product lifecycle status is listed as obsolete, indicating it is no longer actively produced.

FIFOs Memory Feature Summary

• Supports dual configuration options for data width including 16K x 18 and 32K x 9 bit architectures.

FIFOs Memory Applications

FIFOs Memory Procurement Notes

Verify the obsolete lifecycle status before integration planning. Confirm RoHS compliance requirements as indicated by non-compliant markings in available records. Check for moisture sensitivity handling protocols due to BGA packaging constraints. Ensure design-in decisions account for end-of-life availability and potential supply chain discontinuation risks associated with this specific part number.

FIFOs Memory Selection Notes

Consider the 144-pin PBGA form factor for board layout compatibility. Evaluate the 2.5V nominal operating voltage against system power rails. Assess the limited depth and width configurations against buffer requirements. Review alternative components from the same series if higher density or different interface speeds are needed for the target application.

FIFOs Memory Part Context

This component belongs to the 72T1885 series of FIFO memories. It shares the PBGA-144 package style with other devices in the broader 72T family, such as the 72T1845 and 72T1865. These parts generally serve as asynchronous/synchronous buffering solutions in high-speed digital systems requiring reliable data transit management.
