71V124SA12TYGI8

Overview

The Renesas Electronics Corporation 71V124SA12TYGI8 is a 1 Mbit (128K x 8) asynchronous static random-access memory (SRAM) IC. It operates on a single 3.0 V to 3.6 V power supply and features a parallel interface with a maximum access time of 12 ns. The device utilizes a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. It supports an industrial operating temperature range from -40°C to +85°C and includes moisture sensitivity level 3 classification.

Feature Summary

• Utilizes JEDEC center power and ground pinout architecture to reduce noise generation and improve system performance.
• Employs fully static asynchronous circuitry that requires no clocks or refresh cycles for operation.
• Features LVTTL-compatible bidirectional inputs and outputs for direct interfacing with logic systems.

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller architectures
• Temporary storage in industrial control equipment

Procurement Notes

Verify the specific suffix TYGI8 against the manufacturer's official datasheet to confirm package dimensions, lead finish specifications, and RoHS compliance status. Ensure the design accommodates the required 32-SOJ footprint and thermal characteristics for the specified industrial temperature range before finalizing procurement.

Selection Notes

Select this component when a 12 ns access speed and 3.3 V logic compatibility are required within an industrial temperature environment. The center power/ground pinout makes it suitable for designs prioritizing signal integrity and noise reduction over standard peripheral pin configurations.
