71V424L12YG

Overview

The 71V424L12YG is a 4Mbit (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates on a single 3V to 3.6V power supply and features a parallel interface with a maximum access time of 12ns. The device utilizes CMOS technology and is housed in a 36-BSOJ surface-mount package, specifically a 36-SOJ with a width of 10.16mm. It supports an operating temperature range of 0°C to 70°C and complies with RoHS3 standards.

Feature Summary

• Asynchronous operation without requiring external clocks or refresh cycles
• Single 3.3V power supply compatibility for simplified system design
• JEDEC center power and ground pinout configuration to reduce noise generation

Applications

• General-purpose data storage in embedded systems
• Cache memory applications in microcontroller-based designs
• Buffering in industrial control equipment

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures before assembly. Cross-reference datasheet revisions to ensure compatibility with existing board layouts and electrical specifications.

Selection Notes

Select this component when a 4Mbit capacity with 12ns speed is required in a 36-pin SOJ package. Ensure the application environment remains within the commercial temperature range of 0°C to 70°C. Consider the parallel interface requirements and voltage levels against available system resources.
