7204L25J

Overview

The Renesas 7204L25J is a parallel CMOS First-In-First-Out (FIFO) memory device organized as 4K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a PLCC-32 package. The component is classified as an asynchronous FIFO with a maximum data rate of 28.5 MHz and an access time of 25 ns. It supports bidirectional bus directionality and includes relay capability. The device is currently discontinued and marked as End-of-Life.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Bidirectional data bus support for flexible system integration
• Relay capability for signal buffering and driving
• CMOS technology for low power consumption

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between different clock domains
• Temporary storage in high-speed digital communication systems

Procurement Notes

This component is officially discontinued and listed as End-of-Life by the manufacturer. Availability is limited to existing stock or surplus channels. Verify RoHS compliance status, as older revisions may not meet current environmental standards. Confirm package integrity and moisture sensitivity handling requirements before installation due to age.

Selection Notes

Consider the 72V04 series for modern replacements offering similar capacity but with lower voltage operation. Evaluate pin compatibility if substituting directly into existing designs. Ensure new components support required bidirectional bus functionality and meet updated reliability standards for long-term deployment.
