72235LB25J8

Overview

The Renesas Electronics Corporation 72235LB25J8 is a synchronous FIFO memory device with a storage capacity of 2K x 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a PLCC-68 package. The component supports unidirectional data transfer and includes programmable flags for status monitoring. It is classified as an end-of-life product.

Feature Summary

• Synchronous first-in, first-out memory architecture
• Programmable full and empty flag outputs
• Unidirectional bus direction configuration

Applications

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

Procurement Notes

This component is officially discontinued by the manufacturer. Availability is restricted to existing stock or third-party distributors. Verify authenticity carefully due to potential obsolescence risks. Check for moisture sensitivity handling requirements if stored long-term. Confirm package integrity before installation.

Selection Notes

Select this part only if legacy compatibility with the 72235 series is required. Ensure system design accommodates the 4.5 V to 5.5 V operating range. Consider the PLCC-68 footprint constraints during PCB layout. Evaluate alternative modern FIFOs if new production is planned.

Part Context

Part of the Renesas 7200 series synchronous FIFO family. Designed for applications requiring reliable data buffering with simple interface control. Shares architectural similarities with other members like the 72225 and 72245 series variants.

Replacement Considerations

Official substitutes include IDT72235LB25J8. Cross-reference pinouts and electrical specifications before substitution. Verify package compatibility with existing board layouts.
