7200L12SOI8

Overview

The Renesas Electronics Corporation 7200L12SOI8 is an asynchronous CMOS parallel FIFO memory device. It features a storage organization of 256 words by 9 bits, providing a total capacity of 2 kilobits. The component supports bidirectional data bus operations and operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a maximum access time of 12 ns and a maximum clock frequency of 50 MHz. The device is housed in a 28-pin SOIC package and is designed for surface mount installation.

Feature Summary

• Asynchronous operation with bidirectional data bus capability
• CMOS technology for low power consumption
• Single circuit configuration for dedicated buffering

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between different speed logic families
• Temporary data storage in high-speed digital systems

Procurement Notes

Verify the specific suffix designation carefully, as the requested model uses the 'I' variant which typically denotes industrial temperature range or specific packaging, distinct from the 'G' variant found in available documentation. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check for end-of-life notices or discontinuation announcements from Renesas Electronics, as availability may be limited. Ensure the supplier provides valid traceability documents for this legacy component.

Selection Notes

Select this component when a small-capacity, high-speed asynchronous FIFO is required for bidirectional data transfer. The 12 ns access time suits applications needing rapid data handshaking. Compare against the 7200L12SOG8 if commercial temperature range suffices, or consider the 7200L25SOI8 if slower speeds allow for cost reduction. Verify that the 28-SOIC package fits the PCB layout constraints and that the 4.5V to 5.5V supply rail matches the system design.

Part Context

This part belongs to the Renesas 7200L series of asynchronous FIFOs, designed for general-purpose data buffering. The series offers various access times and organizations to suit different interface requirements. As a CMOS device, it provides compatibility with standard TTL and CMOS logic levels while maintaining lower power dissipation compared to older bipolar technologies.

Replacement Considerations

Direct substitutes include the IDT7200L12SOI8, as IDT was acquired by Renesas. Cross-reference pinouts and electrical characteristics with the 7200L12SOG8, noting potential differences in temperature rating or packaging suffixes. Verify functional equivalence before replacing.
