71V124SA15YGI

Overview

The 71V124SA15YGI is a 3.3V CMOS asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage organization of 128K x 8 bits, providing a total capacity of 1 Megabit. The device offers a maximum access time of 15 nanoseconds and operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. It utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. The component supports an industrial temperature range from -40°C to +85°C.

Feature Summary

Utilizes fully static asynchronous circuitry that eliminates the need for external clocks or periodic refresh cycles during operation.
Features JEDEC center power and ground pinout configuration to reduce noise generation and enhance overall system performance.
Incorporates LVTTL-compatible bidirectional inputs and outputs for direct interfacing with standard logic families.

Applications

High-performance processor secondary cache systems
Industrial equipment requiring extended temperature stability
Embedded control units utilizing asynchronous memory interfaces

Procurement Notes

Verify component authenticity through authorized channels as this part number is listed as obsolete. Confirm specific suffix requirements against original design specifications since manufacturing status may affect availability. Ensure compatibility with existing PCB footprints and thermal management strategies before finalizing procurement decisions.

Selection Notes

Select this component when a 15ns access speed and 128K x 8 organization are required for 3.3V applications. Consider the SOJ package constraints for board space and verify that the industrial temperature rating meets environmental demands. Compare against newer synchronous alternatives if higher bandwidth is needed.

Part Context

This SRAM belongs to the 71V124 series, which provides various access times and package options for 3.3V asynchronous memory needs. The SA suffix typically denotes the specific speed grade and package type within the broader product family. This series is designed for applications requiring reliable data retention without complex controller overhead.
