71V256SA15PZGI

Overview

The 71V256SA15PZGI 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 provides a maximum access time of 15 nanoseconds and operates on a single 3.3V power supply with a voltage range of 3V to 3.6V. It utilizes a parallel interface and is housed in a 28-pin Thin Shrink Small Outline Package (TSOP). The component supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation.
• Low standby power consumption contributing to extended battery life in portable applications.
• LVTTL-compatible inputs and outputs for direct interfacing with logic systems.
• Single 3.3V power supply operation simplifying system design.

Applications

• High-performance processor secondary cache memory
• Industrial equipment control systems
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific suffix PZGI confirms the 28-TSOP package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official Renesas documentation, as older variants may differ. Check for Product Change Notifications (PCN) regarding lead content or assembly site changes. Ensure the source document explicitly lists this exact part number to avoid confusion with commercial grade or different package options.

Selection Notes

Select this component when a 32K x 8 asynchronous SRAM with 15ns access speed is required for industrial environments. It is suitable for designs needing LVTTL compatibility and low standby power. Compare against other 71V256SA variants based on package type and temperature rating. Ensure the system voltage aligns with the 3V to 3.6V operating range.

Part Context

This part belongs to the 71V256SA family of 3.3V CMOS Asynchronous SRAMs. The family offers various access times and package options including SOJ and TSOP. The 71V256SA series is designed for high-performance applications such as processor caches. Renesas Electronics continues to support this legacy product line for industrial and commercial uses.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Verify if other suffixes within the 71V256SA family (e.g., 71V256SA15PZG) offer equivalent electrical characteristics with different packaging or temperature grades.
