71V124SA10PHG

Overview

The 71V124SA10PHG is a 1-Mbit (128K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates on a single 3.3V supply with a voltage range of 3.15V to 3.6V and features a 10 ns access time. The device utilizes a parallel interface and is housed in a 32-TSOP II surface-mount package. Designed for industrial reliability, it supports an operating temperature range from -40°C to +85°C. The component is RoHS3 compliant and classified as obsolete.

Feature Summary

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

Applications

• Industrial equipment requiring high-speed data buffering
• Embedded systems utilizing 3.3V logic architectures
• Automotive electronic control units (ECUs)
• Telecommunications infrastructure hardware

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability requires checking authorized distributors for remaining stock or approved replacement part numbers. Sourcing should prioritize manufacturer-recommended substitutes to ensure compatibility and long-term supply chain stability.

Selection Notes

Select this component only if legacy design compatibility with the 71V124 series is required. Engineers must evaluate the 10 ns access speed against current system timing requirements. Consider the TSOP II package dimensions for PCB layout constraints and verify thermal management capabilities within the specified industrial temperature range.

Part Context

The 71V124SA10PHG belongs to the 71V124 family of high-performance CMOS SRAMs. This series is characterized by its low power consumption and robust noise immunity. The specific suffix '10' denotes the 10 nanosecond access speed variant, distinguishing it from slower versions within the same organizational structure.

Replacement Considerations

Renesas recommends the 71V124SA12TYGI as a manufacturer-approved substitute. Verify electrical parameters and pinout compatibility before implementation.
