71V124SA15PHGI8

Overview

The 71V124SA15PHGI8 is a 1-Mbit (128K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It operates on a single 3.0V to 3.6V power supply with a maximum access time of 15 ns. The device utilizes a 32-pin TSOP II surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous parallel interface architecture
• JEDEC center power and ground pinout configuration
• LVTTL-compatible bidirectional I/O lines

Applications

• Industrial equipment control systems
• Embedded data buffering applications
• Consumer electronics memory modules

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Ensure compatibility with existing system voltage levels and timing constraints during integration planning.

Selection Notes

Select this component for designs requiring fast asynchronous access within the specified voltage range. Consider the TSOP II footprint for space-constrained layouts. Evaluate thermal performance against the industrial temperature rating to ensure reliable operation under varying environmental conditions.

Part Context

This part belongs to the 71V124 series of high-performance CMOS SRAMs. It shares architectural similarities with other variants in the family, differing primarily in access speed and packaging options. The series is designed for general-purpose memory applications requiring non-volatile-like retention without refresh cycles.

Replacement Considerations

Check for direct substitutes such as the 71V124SA12PHG8 for faster access times or the 71V124SA15TYGI8 for alternative packaging. Verify pin compatibility and electrical specifications before substitution.
