72T36105L5BB

FIFOs Memory Overview

The Renesas Electronics Corporation 72T36105L5BB is a high-performance First-In-First-Out (FIFO) memory device belonging to the 72T series. It features a storage capacity of 2.25 Mbits, organized as 64K words by 36 bits. The component supports both asynchronous and synchronous operation modes with data rates up to 83 MHz and 200 MHz respectively. Access times are specified at 10 ns for asynchronous mode and 3.6 ns for synchronous mode. It operates within a supply voltage range of 2.375 V to 2.625 V and is housed in a 240-pin PBGA package measuring 19x19 mm.

FIFOs Memory Feature Summary

• Supports dual-mode operation for both asynchronous and synchronous applications
• Provides unidirectional data bus directionality for streamlined integration
• Includes programmable flags and full-word-full/empty status indicators
• Features relay capability for signal buffering and timing adjustment

FIFOs Memory Applications

• High-speed data buffering in telecommunications systems
• Interface bridging between components operating at different clock speeds
• Data acquisition systems requiring precise timing control
• Network equipment packet buffering and processing

FIFOs Memory Procurement Notes

This component has reached End-of-Life status, with discontinuation notices recorded in early 2024. Major distributors such as Mouser and DigiKey currently indicate that the product is not available for sale in many regions. Verification of remaining stock or last-time-buy options requires direct consultation with authorized Renesas channels or legacy inventory holders. Compliance with RoHS standards is noted as non-compliant in official records.

FIFOs Memory Selection Notes

Engineers selecting this part must account for its discontinued status and limited availability. The 36-bit data width is specific and may require careful interface design compared to standard 8-bit or 16-bit alternatives. The 240-PBGA package necessitates appropriate PCB layout considerations for thermal management and signal integrity. Alternative solutions should be evaluated if long-term production stability is required for new designs.

FIFOs Memory Part Context

The 72T36105L5BB is part of the Renesas 72T family of Terasync FIFOs, which also includes variants like the 72T36135ML5BB offering larger capacities. These devices are designed for high-speed memory interfacing tasks. The manufacturer, formerly IDT and now Renesas Electronics, positions this series for demanding industrial and communication applications requiring reliable data flow management without CPU intervention.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Designers should consult Renesas engineering support for qualified replacements within the 72T series or equivalent high-density FIFOs from other manufacturers.
