72215LB25PFI

Overview

The Renesas Electronics Corporation 72215LB25PFI is a synchronous FIFO memory integrated circuit belonging to the 7200 series. It features a storage capacity of 9K bits, organized as 512 words by 18 bits. The device supports unidirectional data transfer with a maximum clock frequency of 40MHz and an access time of 25ns. It operates on a single power supply ranging from 4.5V to 5.5V, with a maximum supply current of 60mA. The component is housed in a 64-pin TQFP package (14x14mm) designed for surface mount installation.

Feature Summary

• Synchronous operation with programmable status flags
• Unidirectional bus directionality for dedicated data flow
• Wide 18-bit data bus width for high-throughput applications

Applications

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

Procurement Notes

This component is officially listed as obsolete and discontinued by the manufacturer. Procurement must rely exclusively on secondary market distributors or surplus inventory channels. Verify part authenticity and condition carefully, as original packaging may be unavailable. Ensure compatibility with existing design specifications before sourcing, as no new production units are available directly from Renesas.

Selection Notes

Select this specific part when a 512x18 synchronous FIFO configuration is required within the 7200 series architecture. It is suitable for designs needing 25ns access times and 40MHz operation under standard 5V logic levels. Consider alternative pin-compatible devices only if the exact depth or width matches are unavailable in the secondary market.

Part Context

The 72215LB25PFI is part of the IDT/Renesas 7200 series of low-power synchronous FIFOs. This series was widely used in embedded systems requiring reliable data buffering. The 'LB' suffix typically denotes low-power CMOS technology, while '25' indicates the 25ns speed grade. The PFI suffix specifies the 64-lead thin quad flat pack package type.

Replacement Considerations

Officially documented equivalent part numbers include IDT72215LB25PFI. Other variants in the same family, such as 72215LB25PF8, offer identical electrical characteristics but differ in reel packaging. Cross-reference datasheets to confirm pinout and functional compatibility before substitution.
