IDT71V256SA10YGI8

Memory IC Overview

The IDT71V256SA10YGI8 is a 3.3V CMOS Asynchronous Static RAM organized as 32K x 8, providing 256 Kbit of storage capacity. It features a fast access time of 10 ns and operates on a single 3.3V power supply with a maximum voltage of 3.6V. The device utilizes fully static asynchronous circuitry, eliminating the need for clocks or refresh cycles. It supports industrial temperature ranges from -40°C to +85°C and is housed in a 28-pin SOJ package.

Memory IC Feature Summary

• Low standby current consumption for extended battery life
• LVTTL-compatible inputs and outputs
• No clocks or refreshes required for operation

Memory IC Applications

• High-performance processor secondary cache
• Industrial systems requiring low power standby
• Battery-powered applications needing data retention

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors due to obsolete status. Confirm package integrity and moisture sensitivity handling procedures before assembly. Check for specific lead-free compliance documentation if required by target market regulations. Ensure compatibility with existing PCB footprints for 28-pin SOJ packages.

Memory IC Selection Notes

Select this component for designs requiring fast 10 ns access times within a 3.3V logic environment. Consider the industrial temperature range suitability for harsh operating conditions. Evaluate the low standby power benefits against system-level cooling requirements. Compare pinout compatibility with alternative SRAM families if space constraints exist.

Memory IC Part Context

This part belongs to the 71V256SA family of 3.3V asynchronous SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members like the IDT71V256SA12YGI8 but offers faster access speeds. The series is designed for applications demanding high reliability and low power consumption in compact surface-mount packages.

Memory IC Replacement Considerations

IDT71V256SA12YGI8: Slower access time (12 ns) but compatible package and voltage. IDT71V256SA15YGI8: Further reduced speed (15 ns) with identical interface. Verify electrical characteristics match design margins when substituting.
