71V256SA15YGI

Memory IC Overview

The 71V256SA15YGI is a 3.3V CMOS Asynchronous Static Random Access Memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage capacity of 256Kb, organized as 32K words by 8 bits. The device offers a maximum access time of 15 ns and utilizes a parallel interface. It operates within a supply voltage range of 3V to 3.6V and supports an industrial temperature range of -40°C to +85°C. The component is housed in a 28-pin Small Outline J-Lead (SOJ) package.

Memory IC Feature Summary

• Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation.
• Low standby current characteristics designed to extend battery life in portable applications.
• LVTTL-compatible inputs and outputs for direct interfacing with logic systems.

Memory IC Applications

• High-performance processor secondary cache memory
• Battery-powered devices requiring low standby power consumption
• Industrial control systems operating in extended temperature environments

Memory IC Procurement Notes

Verify the specific suffix YGI against official datasheets to confirm the 28-SOJ package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check for product end-of-life notices or obsolescence announcements from Renesas Electronics before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 32Kx8 organization with 15 ns speed is required in a 28-pin SOJ form factor. Ensure system design accommodates the 3.3V single supply voltage and LVTTL logic levels. Consider alternative packages such as TSOP if board space constraints differ from the SOJ footprint requirements.
