72235LB15PFI

Overview

The Renesas 72235LB15PFI is a synchronous FIFO memory integrated circuit featuring a storage capacity of 36K bits, organized as 2K words by 18 bits. It operates with a maximum data rate of 66.7MHz and an access time of 10ns. The device supports unidirectional bus direction and programmable flags within a 64-TQFP package. It functions on a supply voltage range of 4.5V to 5.5V with a maximum current consumption of 60mA.

Feature Summary

• Synchronous operation with high-speed data transfer capabilities
• Configurable memory depth and width expansion
• Programmable status flags for buffer management

Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as packaging variations may exist. Validate pin compatibility during integration planning. Check for available alternative packages or successor series from the manufacturer to ensure long-term supply chain stability.

Selection Notes

Select this component for applications requiring 18-bit wide synchronous buffering at 66.7MHz. Ensure the design accommodates the 64-pin TQFP footprint and 4.5V-5.5V power supply constraints. Consider the unidirectional data flow requirement when designing the interface logic. Verify thermal dissipation needs for the surface-mount package under maximum load conditions.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs. It shares architectural similarities with other members like the 72235LB15PFGI8 but differs in packaging type. The series is designed for high-performance memory buffering applications requiring precise timing control and configurable memory structures.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 72235 family. Evaluate the 72235LB15PFGI8 for similar functionality in tape-and-reel packaging. Consult official documentation for any recommended obsolescence alternatives.
