72235LB10JI8

Overview

The Renesas Electronics Corporation 72235LB10JI8 is a synchronous FIFO memory device belonging to the 72205LB-72245LB family. It features an organization of 2K x 18 bits, providing a total storage capacity of 36 kilobits. The component operates with a core voltage of 5.0V and supports an I/O frequency of up to 100 MHz. It utilizes a uni-directional bus architecture and is housed in a 68-pin PLCC package with dimensions of 24.0 x 24.0 mm. The device is designed for industrial temperature ranges from 0°C to 70°C.

Feature Summary

• Synchronous operation with dedicated read and write clock inputs
• Uni-directional data transfer capability
• Programmable status flags including full and empty indicators

Applications

• Data buffering between asynchronous system domains
• Interface bridging in high-speed digital communication systems
• Temporary data storage in embedded processing architectures

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and moisture sensitivity level handling requirements prior to assembly. Review official end-of-life notices for availability constraints and long-term supply implications.

Selection Notes

Select this component when a 2K x 18 synchronous FIFO with 100 MHz performance is required. Ensure compatibility with 5.0V logic levels and PLCC-68 footprint constraints. Consider alternative packages within the same family if surface-mount solutions are preferred over leaded packages.

Part Context

This part belongs to the IDT 722x5LB series of synchronous FIFOs manufactured by Renesas Electronics. The series offers various densities and speeds, with the 72235 variant specifically providing 36K-bit capacity. The 'J' suffix typically denotes the PLCC package type and specific speed grade within the product line.

Replacement Considerations

Official substitutes include other variants within the 72235LB series such as 72235LB10TFG8 or 72235LB15PFGI8, provided pinout and electrical specifications match the design requirements.
