72235LB10TFG8

Overview

The Renesas 72235LB10TFG8 is a synchronous FIFO memory device with a storage capacity of 36K bits, organized as 2K words by 18 bits. It supports unidirectional data transfer at a maximum data rate of 100MHz and features an access time of 6.5ns. The component operates on a single 4.5V to 5.5V power supply with a maximum current consumption of 60mA. It is housed in a 64-TQFP (10x10) surface-mount package and functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Supports high-speed synchronous data buffering for unidirectional communication links
• Provides programmable full and empty flags for status monitoring
• Offers depth and width expansion capabilities for system scalability

Applications

• High-speed data acquisition systems requiring temporary storage
• Buffering interfaces between asynchronous logic domains
• Data processing pipelines in industrial control equipment

Procurement Notes

Verify the specific suffix TFG8 against official Renesas documentation to confirm the exact package dimensions and tape-and-reel specifications. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Confirm that the operating temperature range meets your application's environmental constraints before finalizing procurement.

Selection Notes

Select this component when a 2K x 18 word synchronous buffer is required for unidirectional data flow. It is suitable for applications needing 100MHz operation speeds with low latency. Consider the 64-TQFP package size for PCB layout constraints and verify that the 4.5V to 5.5V voltage range aligns with your system's power supply architecture.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFO memories. It shares architectural similarities with other members like the 72235LB15PFGI8 but differs in speed grade and packaging. The series is designed for high-performance data buffering in digital signal processing and telecommunications applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the same series. Verify if slower speed grades or different package options are available as substitutes. Ensure any replacement maintains the 18-bit data width and synchronous interface requirements.
