72235LB10J

Overview

The Renesas Electronics Corporation 72235LB10J is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 36K organized as 2K by 18 bits. The component supports unidirectional data transfer 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 has a maximum supply current of 60mA. The device is housed in a PLCC-68 package.

Feature Summary

• Synchronous first-in, first-out memory architecture for reliable data buffering
• Supports high-speed data transfer rates up to 100MHz
• Includes programmable status flags to manage buffer levels

Applications

• Data buffering in multiprocessing systems
• Rate matching between asynchronous components
• Interprocessor communication interfaces

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level requirements before integration. Check for end-of-life notices or discontinuation updates from the manufacturer. Ensure proper handling procedures are followed during assembly to prevent electrostatic discharge damage.

Selection Notes

Select this component when a 2K x 18 synchronous FIFO configuration is required. Consider the PLCC-68 package dimensions for board layout compatibility. Evaluate the 6.5ns access time against system timing requirements. Compare power consumption specifications with alternative devices if energy efficiency is a primary design constraint.
