7204L15J8

Overview

The Renesas Electronics Corporation 7204L15J8 is an asynchronous First-In-First-Out (FIFO) memory device featuring a 4K x 9-bit organization. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a PLCC-32 package. The component supports bidirectional data buses with a maximum access time of 15 ns. It is classified as a CMOS FIFO and is currently marked as obsolete by the manufacturer.

Feature Summary

• Asynchronous operation for flexible interface integration
• Bidirectional data bus architecture
• CMOS technology implementation

Applications

• Data buffering in high-speed digital systems
• Interface bridging between disparate clock domains
• Temporary storage in parallel processing architectures

Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Availability is strictly limited to existing stock from third-party distributors or surplus markets. Verification of part authenticity, physical condition, and lot traceability is critical due to the end-of-life status. Sourcing should prioritize reputable suppliers offering comprehensive documentation to ensure compatibility with legacy designs.

Selection Notes

Designers requiring this specific FIFO configuration must evaluate alternative components due to the discontinuation of the 7204L15J8. Selection criteria should focus on matching the 4K x 9-bit depth, 15 ns access speed, and 5V logic levels. Compatibility with the original PLCC-32 footprint may require adapter solutions or PCB redesign if pin-compatible alternatives are not available.

Part Context

The 7204L15J8 belongs to the Renesas 7204L series of asynchronous FIFOs, designed for parallel data transfer applications. This series was widely used in telecommunications and industrial control systems where reliable data buffering between asynchronous modules was required. The J8 suffix denotes the specific PLCC-32 package variant.
