72235LB10TF

Overview

The Renesas Electronics Corporation 72235LB10TF is a synchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 36K bits, organized as 2K words by 18 bits. The component supports unidirectional data bus operation with a maximum data rate of 100MHz and an access time of 6.5ns. It operates within a supply voltage range of 4.5V to 5.5V and features programmable flags for status monitoring. The device is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 10x10mm.

Feature Summary

• Synchronous FIFO architecture supporting high-speed data buffering
• Programmable flag outputs for full and empty status indication
• Unidirectional data bus configuration for dedicated input or output paths

Applications

• High-speed data buffering between asynchronous clock domains
• Interface bridging in telecommunications equipment
• Data acquisition systems requiring temporary storage

Procurement Notes

Verify the exact suffix designation against official Renesas documentation, as the provided model lacks the final character typically indicating package type or temperature grade. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check for end-of-life notices or obsolescence declarations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 2K x 18 word depth is required for synchronous buffering applications. Ensure the design accommodates the 64-pin TQFP footprint and the 4.5V to 5.5V power supply requirements. Consider the 100MHz speed capability relative to system clock constraints and verify that unidirectional operation aligns with the specific data flow direction needs of the circuit design.
