71V416L15BEGI8

Overview

The 71V416L15BEGI8 is a 4 Mbit (256K x 16) asynchronous static random-access memory manufactured by Renesas Electronics. It operates on a single 3.0 V to 3.6 V supply and features a maximum access time of 15 ns. The device utilizes a 48-ball CABGA package with dimensions of 9x9 mm. It supports an industrial temperature range from -40°C to +85°C. The component is classified as End-of-Life, indicating it is no longer in active production.

Feature Summary

• Fully static asynchronous operation requiring no clocks or refresh cycles
• Single 3.3 V CMOS power supply compatibility
• Bidirectional inputs and outputs compatible with LVTTL logic levels

Applications

• High-performance processor secondary cache systems
• Battery backup memory applications
• Industrial control system data storage

Procurement Notes

Verify the End-of-Life status before procurement planning. Confirm that the specific suffix denotes the correct package type and temperature grade. Ensure compliance with RoHS directives if required for the target application. Check for available replacement components due to discontinuation.

Selection Notes

Select this component for designs requiring fast 15 ns access times within a compact 48-ball BGA footprint. Verify voltage compatibility with the 3.0 V to 3.6 V operating range. Consider the industrial temperature rating for harsh environments. Evaluate alternative packages if pinout constraints differ.

Part Context

This part belongs to the 71V416 series of 3.3V CMOS SRAMs. The series offers various access speeds and packaging options. The 'L' designation typically indicates lead-free construction. The 'BEI8' suffix specifies the CABGA package and reel tape-and-reel packaging format.

Replacement Considerations

Consult official Renesas documentation for qualified substitute part numbers. Verify electrical and mechanical compatibility with existing designs.
