7204L30DB

Overview

The Renesas 7204L30DB is a 36K (4K x 9) asynchronous FIFO memory IC in the 7200 series. It features a uni-directional architecture with a maximum data rate of 25MHz and an access time of 30ns. The device operates on a single 5.0V supply, within a range of 4.5V to 5.5V. It utilizes Full and Empty flags for flow control and is housed in a 28-pin CDIP package.

Feature Summary

• Asynchronous first-in/first-out memory architecture
• Uni-directional data transfer capability
• Hardware-based Full and Empty status flag generation

Applications

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

Procurement Notes

Verify the specific suffix 'DB' corresponds to the 28-CDIP package and 30ns speed grade. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current production status as this component may be subject to lifecycle changes.

Selection Notes

Select this part for applications requiring simple uni-directional buffering without complex handshaking. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 30ns access time against your system's timing constraints before finalizing the design.

Part Context

Part of the Renesas 7200 series of dual-port FIFO memories. This series provides reliable data storage solutions for various industrial and commercial applications. The 7204L30DB specifically targets users needing moderate depth and width configurations with standard CMOS compatibility.

Replacement Considerations

Check for direct pin-compatible substitutes from Renesas or other manufacturers offering identical 4Kx9 async FIFO specifications. Verify that any replacement maintains the same 30ns access time and 28-CDIP footprint.
