72245LB10TF8

Overview

The Renesas Electronics Corporation 72245LB10TF8 is a synchronous first-in, first-out (FIFO) memory device with an organization of 4K x 18. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 100 MHz with a maximum access time of 6.5 ns. The component features unidirectional bus directionality and programmable flags for status monitoring. It is housed in a 64-pin TQFP package measuring 10x10 mm and is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Synchronous FIFO architecture with clocked read and write controls
• Programmable flag support for status indication
• Unidirectional data bus configuration

Applications

• Data buffering applications
• Interprocessor communication systems
• Local Area Network (LAN) interfaces

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Current availability is restricted or unavailable through standard distribution channels. Verification of final stock levels and specific discontinuation notices is required before procurement planning. Sourcing should focus on authorized distributors or surplus markets while confirming part authenticity and storage conditions.

Selection Notes

Designers requiring this specific 4K x 18 synchronous FIFO must account for its discontinued status. Selection should prioritize verifying the exact suffix TF8 for the 64-TQFP package variant. Alternative solutions within the 72V245 series may offer similar functionality but operate at different voltage levels, necessitating careful interface compatibility assessment during replacement selection.

Part Context

The 72245LB10TF8 belongs to the 72245LB10 family of high-speed synchronous FIFOs manufactured by Renesas Electronics. This series provides reliable data buffering for digital systems requiring precise timing control. The specific TF8 suffix denotes the surface-mount TQFP packaging format suitable for automated assembly processes in commercial electronic equipment.
