72235LB10TFG

Overview

The Renesas 72235LB10TFG is a synchronous FIFO memory device with a capacity of 36K bits, organized as 2K words by 18 bits. It supports unidirectional data transfer at a maximum clock frequency of 100MHz with a 6.5ns access time. The component operates on a single 4.5V to 5.5V power supply and draws a maximum current of 60mA. It features programmable flags for status monitoring and is housed in a 64-TQFP (10x10) surface-mount package.

Feature Summary

• Provides high-speed synchronous data buffering with 100MHz operation capability
• Includes programmable full and empty flag outputs for flow control
• Supports 18-bit wide data bus architecture for parallel processing

Applications

• High-speed data buffering between asynchronous logic domains
• Interface bridging in telecommunications equipment
• Data acquisition systems requiring precise timing alignment

Procurement Notes

Verify the specific suffix 'TFG' against official Renesas documentation to confirm the exact package dimensions and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 64-TQFP form factor. Confirm RoHS compliance status through the manufacturer's latest environmental declaration, as legacy variants may differ.

Selection Notes

Select this component when an 18-bit data width is required for system integration. The 100MHz speed rating suits applications needing low-latency synchronization. Consider the 64-pin TQFP package constraints for board space. Evaluate if the 2K depth meets buffer requirements compared to deeper alternatives in the 7200 series.

Part Context

This part belongs to the Renesas 7200 series of high-performance synchronous FIFOs. It shares architectural similarities with other members like the 72235LB10J8 but differs in packaging and pinout configuration. The series is designed for demanding digital signal processing and communication interfaces requiring reliable data storage.

Replacement Considerations

The IDT72235LB10TFG is listed as an alias for this component. Verify pin-to-pin compatibility before substitution. Other series members such as the 72235LB15 offer different speed grades but require electrical validation.
