71V124SA15YG8

Memory IC Overview

The 71V124SA15YG8 is a 3.3V CMOS asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 1 Mbit, organized as 128K words by 8 bits. The device offers a maximum access time of 15 ns and operates within a supply voltage range of 3.0 V to 3.6 V. It utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology.

Memory IC Feature Summary

• Utilizes a JEDEC center power and ground pinout configuration to reduce noise generation and improve system performance.
• Employs fully static asynchronous circuitry that requires no clocks or refresh cycles for operation.
• Features LVTTL-compatible bidirectional inputs and outputs for direct interfacing with logic systems.

Memory IC Applications

• High-performance processor secondary cache memory
• Industrial equipment control systems
• Embedded data storage applications

Memory IC Procurement Notes

This component is classified as obsolete and has reached the end-of-life stage, meaning it will be discontinued by the manufacturer. Procurement should focus on verifying final availability through authorized distributors. Buyers must confirm lead times and minimum order quantities directly with suppliers, as stock levels are limited and subject to change without notice.

Memory IC Selection Notes

Select this part when a 1 Mbit asynchronous SRAM with 15 ns speed is required in a 32-pin SOJ package. Ensure the design supports a single 3.3V supply and LVTTL logic levels. Verify that the center power/ground pinout aligns with the PCB layout requirements for noise reduction.

Memory IC Part Context

The 71V124SA15YG8 belongs to the 71V124 series of 3.3V CMOS SRAMs. This family is characterized by its low power consumption via chip deselect and compatibility with standard logic families. The specific suffix indicates the 15 ns speed grade and the 32-pin SOJ packaging option.

Memory IC Replacement Considerations

Verify cross-reference part numbers such as IDT71V124SA15Y8 for potential functional equivalence. Confirm that any substitute matches the 128K x 8 organization, 15 ns access time, and 32-pin SOJ physical dimensions before integration.
