71V124SA10YG8

Overview

The Renesas 71V124SA10YG8 is a 1-Mbit (128K x 8) asynchronous static random-access memory (SRAM) device. It operates from a single 3.3V power supply and features LVTTL-compatible bidirectional inputs and outputs. The component utilizes a JEDEC center power and ground pinout configuration to reduce noise generation and improve system performance. Access times are specified at 10 nanoseconds, with equal access and cycle times. The device employs fully static circuitry, requiring no clocks or refresh cycles for operation.

Feature Summary

• JEDEC center power and ground pinout design reduces noise generation and enhances system performance
• LVTTL-compatible bidirectional inputs and outputs for standard logic interfacing
• Fully static asynchronous architecture eliminates the need for clock signals or refresh cycles

Applications

• General-purpose data storage in embedded systems
• Buffering applications in industrial control equipment
• Cache memory solutions for microcontroller-based designs

Procurement Notes

Verify the specific suffix YG8 against official Renesas documentation to confirm package type and temperature range. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any product change notices or end-of-life announcements that may affect long-term availability. Ensure voltage levels match your system's 3.3V supply specifications.

Selection Notes

Select this component when a 128K x 8 organization is required with 10ns access speed. The center power/ground pinout is critical for noise-sensitive designs. Verify compatibility with LVTTL logic levels. Consider the TSOP II package constraints for PCB layout. Ensure the operating temperature range meets your application environment.
