72235LB10PF8

Overview

The Renesas 72235LB10PF8 is a synchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 36K bits, organized as 2K words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 6.5ns. It operates on a single 4.5V to 5.5V power supply with a maximum current consumption of 60mA. The device is housed in a 64-TQFP package (10x10mm) and is rated for commercial operating temperatures from 0°C to 70°C.

Feature Summary

• Synchronous operation with programmable status flags for precise buffer management
• High-speed data throughput supporting up to 100MHz clock frequencies
• Flexible depth and width expansion capabilities for system integration

Applications

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

Procurement Notes

Verify the specific suffix 'PF8' against official Renesas documentation to confirm package dimensions and lead finish specifications. Confirm end-of-life status and check for available lifecycle notices prior to design-in. Ensure compatibility with existing board space constraints for the 64-TQFP form factor.

Selection Notes

Select this component when a 2K x 18 word synchronous FIFO is required with 6.5ns access speed. Compare against the 72235LB15PFGI8 if lower speed or different packaging is acceptable. Verify that the 0°C to 70°C temperature range meets the operational environment requirements.

Part Context

This part belongs to the IDT/Renesas 72235LB family of synchronous FIFOs. It shares architectural similarities with other members like the 72235LB15PFGI8 but differs in speed grade and package type. The 72235 series is designed for high-performance data buffering applications requiring predictable latency.

Replacement Considerations

Check for direct substitutes within the 72235LB series such as the 72235LB15 variants. Verify pinout compatibility and electrical parameter overlaps before considering alternative manufacturers.
