71V124SA15TYGI

Memory IC Overview

The 71V124SA15TYGI is a 1Mbit (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 15ns access time. The device utilizes a 32-pin BSOJ package with JEDEC center power and ground pinout to reduce noise. It supports LVTTL-compatible bidirectional I/O and functions within an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Utilizes fully static asynchronous circuitry requiring no clocks or refresh cycles for operation.
• Features JEDEC center power and ground pinout architecture to minimize noise generation and enhance system performance.
• Incorporates LVTTL-compatible bidirectional inputs and outputs for direct interface with logic systems.

Memory IC Applications

• High-speed data buffering in industrial control systems
• Cache memory implementation in embedded processing units
• Data storage in telecommunications equipment

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part is obsolete. Confirm package integrity and lead condition upon receipt. Check for RoHS compliance status variations between manufacturing lots. Ensure proper ESD handling procedures are followed during installation due to the CMOS technology used in the device construction.

Memory IC Selection Notes

Select this component when a 15ns access speed is required for 128K x 8 memory configurations. Consider the 32-BSOJ package constraints for PCB layout. Evaluate thermal management requirements for the -40°C to +85°C operating range. Compare against newer asynchronous SRAM families if long-term supply stability is a primary design constraint.

Memory IC Part Context

This device belongs to the 71V124 family of high-performance CMOS static RAMs. It shares architectural similarities with other members like the 71V124SA12PHG but differs in access speed and package type. The family is characterized by low power consumption and compatibility with standard logic interfaces, targeting applications requiring reliable non-volatile-like performance without refresh overhead.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers for this specific obsolete model were not identified in available documentation. Designers should consult manufacturer obsolescence notices for recommended alternatives within the same product line or evaluate equivalent specifications from other vendors.
