7204L12J8

Overview

The Renesas Electronics Corporation 7204L12J8 is an asynchronous FIFO memory device with a storage capacity of 36K bits, organized as 2K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a unidirectional bus architecture. The component provides an access time of 12 ns and supports data rates up to 50 MHz. It is housed in a 32-pin PLCC package and is designed for surface-mount installation.

Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Unidirectional bus architecture simplifies interface design
• CMOS technology ensures low power consumption

Applications

• Data buffering between different clock domains
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the exact suffix designation against official Renesas documentation, as variations such as JG8 or J8 may indicate differences in packaging or compliance status. Confirm current production status, as this part number may be discontinued or subject to limited availability. Ensure moisture sensitivity level requirements are met during handling and storage procedures.

Selection Notes

Select this component when a 2K x 9 asynchronous FIFO with 12 ns access time is required. Consider the 32-PLCC package constraints for PCB layout. Evaluate if the unidirectional bus direction meets system requirements compared to bidirectional alternatives. Verify that the 4.5 V to 5.5 V operating voltage aligns with the target system power rails.

Part Context

This device belongs to the Renesas 7204 series of asynchronous FIFO memories. The series typically offers various speed grades and organization options. The 7204L12J8 specifically denotes the 12 ns speed grade variant within this family, providing a balance between performance and power efficiency for general-purpose memory applications.
