72235LB15J

Overview

The Renesas Electronics Corporation 72235LB15J is a synchronous FIFO memory device with a capacity of 36K bits, organized as 2K words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 66.7 MHz with an access time of 15 ns. The component is housed in a 68-PLCC package and features programmable flags for status monitoring.

Feature Summary

• Synchronous operation supporting high-speed data buffering
• Programmable full and empty flag outputs for flow control
• Unidirectional bus architecture for dedicated data paths

Applications

• High-speed data buffering between asynchronous systems
• Interface bridging in telecommunications equipment
• Data acquisition system temporary storage

Procurement Notes

Verify current availability status as the product may be discontinued or subject to limited supply constraints. Confirm RoHS compliance requirements against specific project standards, noting that older revisions may not meet current environmental directives. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this component when a 2Kx18 synchronous FIFO configuration is required. Compare performance metrics such as access time and clock frequency against alternative models like the 72235LB25J if higher speed is needed. Verify package compatibility with existing PCB layouts, specifically checking for PLCC footprint requirements versus other available options.

Part Context

This part belongs to the 7200 series of synchronous FIFOs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family but differs in speed grade and package type. The 72235LB15J represents a specific performance tier within the broader memory storage portfolio designed for industrial and commercial applications.

Replacement Considerations

The IDT72235LB15J is listed as an alias for this component. Verify pinout and electrical specifications match exactly before substitution. No other cross-manufacturer replacements are confirmed in public documentation.
