72235LB25JI

Overview

The Renesas Electronics Corporation 72235LB25JI is a synchronous FIFO memory device belonging to the 7200 series. It features a storage organization of 2K x 18 bits, providing a total capacity of 36 kilobits. The component operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a PLCC-68 package. This part supports unidirectional data transfer with programmable status flags for buffer management.

Feature Summary

• Synchronous first-in-first-out memory architecture supporting simultaneous read and write operations
• Programmable status flags including Full, Empty, and Half-Full indicators for precise buffer control
• Unidirectional data bus configuration optimized for single-direction data flow applications

Applications

• Multiprocessing systems requiring rate buffering between asynchronous domains
• Data acquisition systems needing temporary storage before processing
• Communication interfaces managing variable data throughput rates

Procurement Notes

Verify exact availability as this specific suffix variant may be discontinued or limited. Confirm package integrity upon receipt due to moisture sensitivity classification. Ensure design compatibility with existing 5V logic levels and PLCC-68 footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 2K x 18 synchronous FIFO is required with 5V operation. Compare against other 72235 variants based on access speed and package type. Ensure system timing constraints align with the specified clock frequency capabilities of the selected speed grade.

Part Context

This device is part of the Renesas 7200 series of high-speed FIFO memories. It shares functional compatibility with previous generations while offering expanded depth and width options. The 72235LB25JI specifically targets applications requiring moderate density with fast synchronous access times in industrial environments.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 7200 series family. Verify if alternative speed grades or package types from Renesas meet the original design specifications without requiring board layout changes.
