7204L12SOG8

Overview

The Renesas Electronics Corporation 7204L12SOG8 is an asynchronous FIFO memory device with a storage capacity of 36.86 kbit, organized as 4K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum clock frequency of 50 MHz with a 12 ns access time. The component utilizes a 28-SOIC package and supports unidirectional bus directionality. It is designed for surface-mount installation and includes relay capability.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Supports data buffering between systems with different timing requirements
• Includes relay capability for signal transmission

Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous logic circuits
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation to confirm it denotes the reel packaging format rather than a functional variation. Ensure compatibility with RoHS3 standards and check moisture sensitivity level (MSL) ratings before assembly. Confirm that the 28-SOIC footprint matches your PCB design constraints and that the 12 ns access time meets your system's timing requirements.

Selection Notes

Select this component when a 4K x 9 asynchronous FIFO is required with 12 ns performance. Compare against the 7204L15 series if slower speeds are acceptable but wider availability is needed. Consider the 7204L12JG variant if PLCC packaging is preferred over SOIC. Verify that the 50 MHz maximum frequency aligns with your application's clock domain limits.

Part Context

This part belongs to the Renesas 7204L series of asynchronous FIFO memories. It is functionally equivalent to the IDT7204L12SOG8 designation. The series provides non-volatile-like data retention during power cycles via static RAM technology, suitable for applications requiring reliable temporary data storage without complex control logic.

Replacement Considerations

IDT7204L12SOG8 is a confirmed substitute part number.
