71V124SA10TYG

Overview

The Renesas 71V124SA10TYG is a static random-access memory (SRAM) device organized as 128K words by 8 bits, providing a total storage capacity of 1 megabit. It operates on a single 3.3V power supply and features asynchronous parallel interface technology. The component utilizes a JEDEC standard center power and ground pinout configuration to minimize electrical noise and enhance system performance stability. Access times are specified at 10 nanoseconds for the commercial temperature grade variant. The inputs and outputs are compatible with LVTTTL logic levels, ensuring interoperability with standard digital systems without requiring additional level shifting circuitry.

Feature Summary

• Utilizes a JEDEC standard center power and ground pinout architecture to reduce signal noise and improve overall system reliability.
• Features fully static asynchronous circuitry that eliminates the need for external clock signals or periodic data refresh cycles.
• Incorporates LVTTTL-compatible bidirectional inputs and outputs for direct integration with standard logic families.
• Operates from a single 3.3V power supply with low power consumption capabilities achieved through chip deselect modes.

Applications

• Data buffering in high-speed digital processing systems
• Cache memory implementation in embedded controllers
• Temporary storage in industrial automation equipment
• Memory expansion for microprocessor-based applications

Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm the exact access time and temperature range. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check for product discontinuation notices or last-time-buy notifications as availability may be limited. Ensure the selected package type matches the intended PCB layout constraints.

Selection Notes

Select this component when a 1-megabit asynchronous SRAM with 10-nanosecond access speed is required for 3.3V logic systems. Consider the center power/ground pinout for designs prioritizing noise reduction over standard peripheral pin configurations. Evaluate thermal operating ranges to ensure the commercial grade meets environmental specifications. Verify LVTTTL compatibility with existing bus architectures before finalizing the design.

Part Context

This part belongs to the 71V124 family of 3.3V CMOS SRAMs manufactured by Renesas Electronics. The family offers various access speeds and package options to suit different performance and form-factor requirements. These devices are designed for general-purpose memory applications where fast, random access to volatile data is essential for system operation.

Replacement Considerations

Cross-reference with other 71V124 variants offering different access times or package styles if pinout compatibility allows. Verify functional equivalence with IDT-branded equivalents under current Renesas ownership. Ensure substitute parts maintain the same center power/ground pinout configuration to avoid PCB redesign.
