72235LB25JI8

Overview

The Renesas Electronics Corporation 72235LB25JI8 is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 36K bits, organized as 2K words by 18 bits. The component operates with a maximum data rate of 40MHz and an access time of 15ns. It utilizes a unidirectional bus configuration and supports programmable flags. The device is designed for surface mount installation in a 64-PLCC package and functions within a supply voltage range of 4.5V to 5.5V.

Feature Summary

• Synchronous first-in-first-out memory architecture
• Programmable full and empty flag support
• Unidirectional data bus interface

Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous logic blocks
• Temporary data storage in communication protocols

Procurement Notes

Verify the exact suffix designation against official Renesas documentation, as availability varies by package type. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Check for end-of-life notices or discontinuation updates from the manufacturer to ensure long-term supply stability for production cycles.

Selection Notes

Select this component when a 2Kx18 synchronous FIFO with 15ns access speed is required. Ensure the system design accommodates the PLCC-64 footprint and 4.5V to 5.5V power requirements. Consider the unidirectional nature of the data path during schematic design and verify that programmable flag outputs meet the control logic timing constraints.
