72251L15JG8

Overview

The Renesas Electronics Corporation 72251L15JG8 is a synchronous FIFO memory device with a storage capacity of 72K bits, organized as 8K words by 9 bits. It features an access time of 10 ns and supports data rates up to 66.7 MHz. The component operates on a single power supply ranging from 4.5 V to 5.5 V, with a maximum supply current of 50 mA. It utilizes a unidirectional bus interface and is housed in a 32-PLCC package (14x11.46 mm). The device functions within a temperature range of -40°C to +85°C.

Feature Summary

• Synchronous FIFO architecture supporting high-speed data buffering
• Programmable flags for status monitoring
• Unidirectional data bus configuration
• Surface-mount PLCC packaging for automated assembly

Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage
• Network equipment packet buffering

Procurement Notes

Verify the specific suffix JG8 against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Check for recent Product Change Notices regarding material composition or assembly site changes. Confirm end-of-life status and availability through authorized distributors, as this part may be discontinued. Ensure RoHS compliance documentation matches current regulatory requirements for your region.

Selection Notes

Select this component when a synchronous FIFO with 10 ns access time and 66.7 MHz capability is required. Compare against the 72V05L15 series if asynchronous operation or lower voltage (3V) is needed. Consider the 72T18125 series for higher speed or wider data width applications. Verify that the 32-pin PLCC package fits the PCB footprint constraints and that the 4.5V to 5.5V supply range aligns with the system design.

Part Context

This part belongs to the IDT 722x1 family of synchronous FIFOs, designed for high-performance data buffering. It is manufactured by Renesas Electronics Corporation, formerly Integrated Device Technology. The 72251 variant specifically offers 8K x 9 organization. This family is known for low power consumption and flexible programmable flag options, making it suitable for complex digital signal processing and telecommunications applications.

Replacement Considerations

Check for direct substitutes such as the IDT72251L15JGI. Verify pin-to-pin compatibility with other 32-pin PLCC synchronous FIFOs from different manufacturers if sourcing alternatives. Review datasheets for any differences in flag logic or clock specifications.
