71V124SA15PHG

Overview

The 71V124SA15PHG is a 1Mb (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 3V to 3.6V. The device features a 15 ns access time and utilizes LVTTL-compatible bidirectional inputs and outputs. It is housed in a 32-pin TSOP II package with dimensions of 20.95 mm x 10.16 mm x 1.0 mm and a 1.27 mm pitch. The component supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes JEDEC center power and ground pinout architecture to reduce noise generation and improve system performance.
• Employs fully static asynchronous circuitry that eliminates the need for external clocks or periodic refresh cycles.
• Features LVTTL-compatible bidirectional I/Os designed for direct interface with standard logic systems.

Applications

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

Procurement Notes

Verify the specific suffix 'PHG' against official Renesas documentation to confirm the exact package type and lead finish specifications. Confirm current production status, as this series may be subject to end-of-life notices. Ensure compatibility with the required 3.3V logic levels and thermal operating range before finalizing procurement decisions.

Selection Notes

Select this component when a 1Mb capacity with 15 ns speed is required in a compact surface-mount form factor. It is suitable for designs needing low-power static operation without clock synchronization. Verify that the 32-pin TSOP II footprint matches the PCB layout constraints and that the -40°C to +85°C industrial temperature rating meets environmental requirements.

Part Context

This part belongs to the 71V124 family of high-performance CMOS SRAMs from Renesas. The family offers various speed grades and packaging options to support diverse embedded memory needs. The 71V124SA15PHG specifically targets applications requiring reliable, fast, and compact volatile memory solutions within industrial and commercial temperature ranges.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference speed grades and package dimensions carefully. Generic equivalents may not match the specific JEDEC pinout or electrical characteristics required for seamless integration.
