71V124SA15YG

Overview

The IDT 71V124SA15YG is a standard asynchronous static random-access memory (SRAM) integrated circuit manufactured by Integrated Device Technology. It features a memory organization of 128K words by 8 bits, providing a total capacity of 1 Megabit. The device supports a maximum access time of 15 nanoseconds and operates within a single 3.3-volt power supply range. It utilizes CMOS technology for low-power consumption and is housed in a 32-pin Thin Small Outline Package (TSOP II).

Feature Summary

• Asynchronous parallel interface architecture for flexible system integration.
• Low-power CMOS technology designed to minimize energy consumption during operation.
• Single 3.3V power supply requirement simplifying voltage regulation design.

Applications

• Data buffering in high-speed digital signal processing systems.
• Cache memory implementation in embedded microcontroller architectures.
• Temporary storage in industrial control and automation equipment.

Procurement Notes

Verify the specific suffix 'YG' against official Renesas or IDT documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for 32-pin TSOP packages. Confirm RoHS compliance status if required for current manufacturing standards. Check for product discontinuation notices as IDT assets are managed by Renesas Electronics.

Selection Notes

Select this component when a 15ns access speed and 1Mbit density are required for asynchronous applications. Consider the 32-pin TSOP form factor for space-constrained designs. Evaluate alternatives only if faster access times or different voltage levels are necessary. Verify that the 3.3V operating range aligns with the target system's power rails.

Part Context

This part belongs to the IDT 71V124 family of 1-Mbit SRAM devices. The family offers various speed grades and packaging options to suit different performance and size requirements. IDT was acquired by Renesas Electronics, which continues to support and distribute these legacy memory products under the Renesas brand portfolio.

Replacement Considerations

Cross-reference with other 71V124 variants such as 71V124SA10 or 71V124SA12 for faster speeds. Verify pinout compatibility before substituting with generic 1Mbit SRAMs from other manufacturers.
