72T36105L6-7BB

FIFOs Memory Overview

The Renesas 72T36105L6-7BB is a high-performance First-In-First-Out (FIFO) memory device supporting both asynchronous and synchronous operations. It features a storage capacity of 2.25M bits, organized as 64K words by 36 bits. The component operates within a supply voltage range of 2.375 V to 2.625 V. It supports data rates up to 66 MHz in asynchronous mode and 150 MHz in synchronous mode, with corresponding access times of 12 ns and 3.8 ns respectively. The device 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 flow capability
• Includes programmable flags for status monitoring
• Features FWFT (First Word Fall Through) support

FIFOs Memory Applications

• High-speed data buffering in communication systems
• Interface bridging between components operating at different clock speeds
• Data acquisition systems requiring temporary storage

FIFOs Memory Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Production has ceased, and availability is strictly limited to existing stock or surplus channels. Verification of authenticity and physical condition is critical due to the discontinued status. Buyers should confirm the specific revision suffix and manufacturing date code before procurement to ensure compatibility with existing designs.

FIFOs Memory Selection Notes

Designers should evaluate this part primarily for legacy system maintenance or replacement scenarios where the specific 64K x 36 width and Terasync interface are required. Due to its EOL status, new designs must consider alternative modern FIFO solutions with updated packaging and RoHS compliance. Verify that the 240-PBGA footprint matches the target PCB layout constraints and thermal requirements.

FIFOs Memory Part Context

The 72T36105 series belongs to Renesas' Terasync family of FIFO memories, designed for high-speed data handling. This specific model represents a variant optimized for synchronous performance while maintaining asynchronous compatibility. It is part of a broader portfolio used in networking and industrial equipment, though this particular item is no longer in active production.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Given the End-of-Life status, direct pin-to-pin replacements from other manufacturers may require schematic and layout modifications. Consult official Renesas resources for current recommended alternatives.
