72235LB15TFGI8

Overview

The Renesas Electronics Corporation 72235LB15TFGI8 is a synchronous FIFO integrated circuit belonging to the 7200 series. It features a storage capacity of 36K bits, organized as 2K words by 18 bits. The device supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 60mA. The component is housed in a 64-TQFP package measuring 14x14mm and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with programmable status flags
• Unidirectional data bus architecture
• Extended industrial temperature range capability

Applications

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

Procurement Notes

This component has been officially discontinued by the manufacturer. Product discontinuance notifications confirm that production has ceased. Verification of availability should focus on existing stock or authorized distributors rather than new manufacturing orders. Compliance with RoHS3 standards applies to specific suffix variants; verify environmental compliance documentation for this specific part number before integration.

Selection Notes

Designers requiring equivalent performance must evaluate alternative synchronous FIFOs within the same memory organization class. Key selection criteria include matching the 18-bit data width, ensuring compatible 5V logic levels, and verifying package footprint compatibility with the 64-TQFP form factor. Thermal management considerations remain consistent with the specified 60mA maximum current draw under standard operating conditions.

Part Context

The 72235LB15TFGI8 is part of the IDT/Renesas 7200 series of high-performance synchronous FIFOs. This family is designed for applications requiring fast data throughput and flexible interface capabilities. The 'LB' designation typically indicates low-power consumption characteristics relative to earlier generations, while the '15' suffix denotes the 10ns access time speed grade within the product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material due to the component's discontinued status. Engineers should consult official replacement guides or contact the manufacturer directly for qualified alternatives.
