71V124SA10TYG8

Overview

The Renesas Electronics Corporation 71V124SA10TYG8 is a 3.3V CMOS static random-access memory (SRAM) organized as 128K x 8 bits, providing a total storage capacity of 1 Megabit. It operates with a maximum access time of 10 nanoseconds and utilizes a single 3.3V power supply. The device features an asynchronous interface with LVTTL-compatible bidirectional inputs and outputs. It employs fully static circuitry that requires no clocks or refresh cycles for operation.

Feature Summary

• JEDEC center power and ground pinout configuration to reduce noise generation and improve system performance
• LVTTL-compatible bidirectional inputs and outputs for direct interfacing with logic families
• Fully static asynchronous architecture eliminating the need for external clock signals or periodic refresh operations

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller-based designs
• Temporary storage in industrial control applications

Procurement Notes

Verify component authenticity through authorized channels due to potential availability from secondary markets. Confirm package integrity and moisture sensitivity level handling requirements prior to assembly. Review manufacturer documentation for any product change notices or lifecycle status updates affecting long-term supply continuity.

Selection Notes

Select this component when low latency and deterministic access times are critical for system responsiveness. The 10ns speed grade suits high-performance asynchronous interfaces. Ensure voltage levels align with the 3.3V supply requirement and verify compatibility with LVTTL logic standards in the target design environment.

Part Context

This part belongs to the 71V124 family of 3.3V SRAMs, which offers various speed grades including 10ns, 12ns, 15ns, and 20ns options. The family shares a common 128K x 8 organization and JEDEC center power/ground pinout standard. Variants differ primarily in access time specifications and package types such as SOJ or TSOP.
