72235LB10JG

Overview

The Renesas Electronics Corporation 72235LB10JG is a synchronous FIFO memory device belonging to the 72235 series. It features a storage capacity of 36K bits, organized as 2K words by 18 bits. The component operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a PLCC-68 package. It supports unidirectional data transfer with programmable flags for status monitoring.

Feature Summary

• Synchronous operation for reliable data buffering
• Programmable full and empty flag outputs
• Unidirectional bus interface architecture

Applications

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

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Confirm RoHS compliance status and moisture sensitivity level prior to integration, as legacy stock may vary in environmental certification and handling requirements.

Selection Notes

Engineers replacing this part must account for its discontinued status when designing new hardware. Verify that alternative components match the 18-bit width and 2K depth specifications. Ensure the replacement package type is compatible with existing PCB footprints or design a mechanical adapter if pinouts differ significantly from the PLCC-68 form factor.

Part Context

The 72235LB10JG is part of the broader 72235 family of synchronous FIFOs manufactured by Renesas Electronics. This family provides various access times and packaging options for different speed and density requirements. The specific JG suffix denotes the PLCC-68 plastic leaded chip carrier package variant within this product line.
