71V124SA15TY

Overview

The IDT71V124SA15TYI is a 1Mbit (128K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates with a supply voltage range of 3V to 3.6V and features a maximum access time of 15ns. The device utilizes a parallel interface and is housed in a 32-BSOJ surface-mount package with a width of 0.300 inches (7.62mm). It supports an operating temperature range from -40°C to +85°C. The component is classified as non-RoHS compliant and has reached end-of-life status.

Feature Summary

• Asynchronous parallel SRAM architecture for standard data storage
• CMOS technology ensuring low power consumption
• Wide industrial operating temperature capability

Applications

• Industrial control systems requiring reliable volatile memory
• Embedded applications within the consumer electronics sector
• Telecommunications equipment utilizing asynchronous interfaces

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability is restricted to existing stock held by distributors or secondary market suppliers. Buyers must confirm the specific manufacturing date code and physical condition prior to acquisition, as original manufacturer support is unavailable. Compliance with current environmental regulations should be verified against local requirements due to its non-RoHS status.

Selection Notes

Designers seeking this specific part number must account for its obsolete status when planning long-term production cycles. Alternative solutions within the same family, such as variants with different access speeds or packaging options, may offer better availability. Engineers should evaluate pin-compatible replacements that meet the required 15ns access time and 3.3V logic levels to ensure seamless integration without redesigning the board layout.

Part Context

The IDT71V124SA15TYI belongs to the broader 71V124 series of high-speed CMOS static RAMs originally developed by Integrated Device Technology. Following the acquisition of IDT by Renesas Electronics, product lines were consolidated under the Renesas portfolio. This specific model represents a legacy component designed for general-purpose memory applications where moderate speed and standard parallel connectivity are sufficient.

Replacement Considerations
