72251L15PFGI

Overview

The Renesas 72251L15PFGI is a synchronous FIFO memory device with a storage capacity of 72K bits, organized as 8K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 66.7 MHz. The component features a 10 ns access time and draws a maximum supply current of 50 mA. It is housed in a 32-pin PLCC package and functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Synchronous operation with unidirectional bus direction for dedicated data flow management
• Supports programmable flags to indicate full and empty buffer states
• Surface-mount installation in a compact 32-PLCC package

Applications

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

Procurement Notes

Verify the exact suffix PFGI against official Renesas documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level prior to PCB assembly. Check for obsolescence notices or alternative package options if long-term supply stability is required for production.

Selection Notes

Select this component when a 72K-bit synchronous FIFO with 9-bit width is required. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the 32-PLCC package constraints for board layout and thermal management during high-frequency operation at 66.7 MHz.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFO memories. It provides reliable data buffering capabilities for digital signal processing and communication applications. The device integrates standard control signals for efficient read and write operations without external timing complexity.

Replacement Considerations

IDT72251L15JGI is a confirmed substitute offering identical functionality in a 32-PLCC package.
