7204L25JI8

Overview

The Renesas 7204L25JI8 is an asynchronous FIFO memory device with a 4K x 9 organization, providing 36 Kbits of storage capacity. It operates within a 4.5 V to 5.5 V supply voltage range and features a 25 ns access time. The component supports a maximum data rate of 28.5 MHz and draws a maximum supply current of 60 mA. It is housed in a 32-PLCC package and functions as a unidirectional buffer for parallel data transfer.

Feature Summary

• Supports asynchronous read and write operations for independent clock domains
• Includes status flags such as Full and Empty to manage data flow
• Provides retransmit capability to reset the read pointer

Applications

• Multiprocessing systems requiring data buffering
• Rate matching between different speed components
• Parallel data interface buffering

Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance. Confirm moisture sensitivity level handling requirements during assembly. Check for obsolescence notices or discontinuance alerts from Renesas Electronics. Ensure the specific suffix matches the required package and temperature grade.

Selection Notes

Select this part for applications requiring 4K x 9 depth with 5V logic compatibility. Compare against the 72V04 series if 3.3V operation is required instead of 5V. Verify that the 25 ns access time meets system timing constraints. Consider the PLCC package availability for PCB layout design.

Part Context

This component belongs to the 7204L family of asynchronous FIFO memories. It is functionally compatible with the broader 720X series. The device is designed for high-speed parallel data buffering in industrial and commercial environments.

Replacement Considerations
