7201LA20J8

Overview

The Renesas Electronics Corporation 7201LA20J8 is an asynchronous FIFO memory integrated circuit designed for high-speed data buffering applications. It features a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The device supports a maximum data rate of 33.3MHz with a typical access time of 20ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 80mA. The component utilizes a 32-pin PLCC package with J-leads, suitable for surface mount installation. It functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Supports relay capability to maintain data integrity during bus transitions or system resets.
• Fixed depth and width configuration provides dedicated buffer space without programmable logic overhead.

Applications

• Data buffering between microprocessors and peripheral devices operating at different clock speeds
• Interface bridging in communication systems requiring temporary data storage
• Digital signal processing pipelines needing intermediate memory staging

Procurement Notes

Verify the specific suffix J8 confirms the 32-PLCC package and lead type. Confirm RoHS compliance status as sources indicate non-compliance. Check end-of-life notices for discontinuation impact. Validate supplier authenticity due to potential legacy part availability issues. Ensure environmental specifications meet project requirements.

Selection Notes

Choose this component when a fixed 512x9 asynchronous buffer is required. Compare against other 7201 series variants if different access times or capacities are needed. Verify voltage compatibility with the target system's 5V logic levels. Consider package constraints regarding the 32-PLCC footprint availability.

Part Context

This part belongs to the Renesas 7201L series of asynchronous FIFOs. It shares architectural similarities with other members like the 7202LA20J8 but differs in memory depth. The series is characterized by CMOS technology and parallel interfaces. It serves as a legacy solution for older industrial and communication equipment designs.

Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify functional equivalence for asynchronous buffering needs. Review datasheets for any changes in electrical characteristics or package dimensions before substitution.
