71V124SA15TYGI8

Memory IC Overview

The 71V124SA15TYGI8 is a 1-Mbit (128K x 8) asynchronous static random-access memory manufactured by Renesas Electronics. It operates on a single 3.3V supply with a voltage range of 3.0V to 3.6V and features a 15 ns access time. The device utilizes LVTTL-compatible bidirectional I/Os and employs JEDEC center power/ground pinout architecture to minimize noise. It is housed in a 32-pin Small Outline J-Lead (SOJ) surface-mount package.

Memory IC Feature Summary

• Utilizes fully static asynchronous circuitry requiring no clock signals or refresh cycles for operation.
• Features LVTTL-compatible bidirectional inputs and outputs for direct interface with logic systems.
• Incorporates JEDEC center power and ground pinout design to reduce electromagnetic interference.

Memory IC Applications

• Asynchronous data buffering in embedded systems
• Cache memory implementation in industrial control units
• General-purpose volatile storage in consumer electronics

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part is designated as obsolete. Confirm that the specific suffix matches required packaging and compliance standards. Check for moisture sensitivity handling requirements prior to assembly. Ensure compatibility with existing board layouts due to the SOJ-32 form factor.

Memory IC Selection Notes

Select this component for applications requiring low-power 3.3V SRAM with fast access speeds. Consider the SOJ-32 package constraints for PCB space. Evaluate system noise levels, as the center power pinout offers improved performance over standard configurations. Verify that the LVTTL logic levels align with the host processor specifications.

Memory IC Part Context

This device belongs to the 71V124SA series of high-speed CMOS static RAMs. It shares architectural similarities with other members like the 71V124SA12TYG but differs in access speed and specific package variations. The series is characterized by its use of advanced CMOS technology for low power consumption.

Memory IC Replacement Considerations
