71V256S12YG8

Overview

The Renesas Electronics Corporation 71V256S12YG8 is a 3.3V CMOS Asynchronous Static RAM organized as 32K x 8. It features a 12 ns access time and operates on a single 3.3V power supply. The device utilizes LVTTL-compatible inputs and outputs, ensuring compatibility with standard logic families. It is housed in a 28-pin SOJ package and supports commercial temperature ranges. The component employs fully static asynchronous circuitry, eliminating the need for clocks or refresh cycles during operation.

Feature Summary

• Low standby current characteristics contribute to extended battery life when in standby mode.
• Fully static asynchronous circuitry requires no clocks or refreshes for operation.
• Inputs and outputs are LVTTL-compatible for broad system integration.

Applications

• High-performance processor secondary cache
• Battery-powered systems requiring low standby power
• General-purpose memory storage in embedded applications

Procurement Notes

Verify the exact part number spelling against official documentation, as '71V256S' may be a variant of the '71V256SA' series. Confirm availability status, as many variants in this family are listed as obsolete or discontinued. Ensure the specific suffix 'YG8' matches the required reel packaging format if automated assembly is planned. Cross-reference with Renesas official datasheets for final electrical specifications before procurement.

Selection Notes

Select this component for designs requiring fast asynchronous access without clock synchronization. The 3.3V operating voltage makes it suitable for modern low-voltage digital systems. Consider the 28-pin SOJ package constraints for PCB layout. Verify that the LVTTL input/output levels align with the driving and receiving logic interfaces in the target application architecture.

Part Context

This component belongs to the 71V256SA series of high-speed SRAMs from Renesas Electronics. The series is designed for applications needing reliable, non-volatile-like performance with volatile speed. Variants differ primarily by access speed, temperature grade, and physical package type. The SA designation typically indicates the 3.3V logic family within the broader 71V256 product line.
