71V256S10YG

Memory IC Overview

The IDT71V256S10YG 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 utilizes a parallel interface and offers a maximum access time of 10 ns. It operates within a supply voltage range of 3.0V to 3.6V and supports an industrial temperature range from -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 operation requiring no clocks or refresh cycles
• Low power standby mode with guaranteed consumption under 6.6mW
• CMOS level chip select for efficient battery life extension
• Direct TTL-compatible input and output interfaces

Memory IC Applications

• Battery-powered portable electronic devices
• Industrial control systems
• Communication equipment buffers
• Embedded system data storage

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as historical records indicate non-compliance for this specific part number variant. Confirm the manufacturer's discontinuation status and check for valid replacement components before procurement planning. Ensure the supplier provides official datasheets matching the 28-SOJ package specifications.

Memory IC Selection Notes

Select this component when a 10 ns access speed is required for 32Kx8 memory configurations. It is suitable for designs needing low standby power and 3.3V operation. Verify that the 28-SOJ package fits the board layout constraints. Consider the industrial temperature rating for harsh environments.

Memory IC Part Context

This part belongs to the 71V256SA family of high-performance SRAMs. It shares architectural similarities with other variants like the IDT71V256SA20YI but offers faster access times. The SOJ package distinguishes it from surface-mount alternatives, targeting specific legacy or specialized mounting requirements.

Memory IC Replacement Considerations

Check for direct pin-to-pin replacements such as the AS7C3256A series from Alliance Memory. Verify electrical compatibility regarding access times and voltage levels. Ensure the substitute component matches the 28-SOJ package form factor.
