72251L15JGI8

Overview

The 72251L15JGI8 is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 72K bits, organized as 8K words by 9 bits. The component supports data rates up to 66.7 MHz with an access time of 10 ns. It operates on a single supply voltage ranging from 4.5 V to 5.5 V and draws a maximum supply current of 50 mA. The device is housed in a 32-lead PLCC package and is designed for surface mount installation.

Feature Summary

• Synchronous operation with unidirectional bus direction
• Supports programmable flags for status monitoring
• Compatible with standard 32-PLCC surface mount packaging

Applications

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

Procurement Notes

Verify the specific suffix JGI8 against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Check for obsolescence notices or alternative part recommendations directly from the manufacturer.

Selection Notes

Select this component when a synchronous FIFO with 10 ns access time and 66.7 MHz capability is required. Ensure the design utilizes a 4.5 V to 5.5 V power supply. Verify that the 32-PLCC package fits the PCB layout constraints and that unidirectional data flow meets the system architecture needs.

Part Context

This part belongs to the Renesas 7200 series of FIFO memories. It is distinct from asynchronous variants like the 7201 series and higher-speed Terasync models. The 72251 variant specifically offers 8Kx9 organization, differentiating it from other capacities within the same family.

Replacement Considerations

Official direct replacements include IDT72251L15JGI. Verify cross-reference compatibility through Renesas datasheets before substitution.
