Overview
The 71V256SA15YGI8 is a 3.3V CMOS Asynchronous Static Random Access Memory (SRAM) manufactured by Renesas Electronics Corporation. It features a memory organization of 32K x 8, providing a total storage capacity of 256 Kbit. The device operates with a maximum access time of 15 ns and utilizes a parallel interface. It supports a supply voltage range from 3 V to 3.6 V and functions within an industrial temperature range of -40°C to +85°C. The component is housed in a 28-pin Small Outline J-Lead (SOJ) package designed for surface mount technology.
Feature Summary
- Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation
- Low standby power consumption ensuring extended battery life in portable applications
- LVTTL-compatible inputs and outputs for direct interfacing with logic systems
- Single 3.3V power supply requirement simplifying system design
Applications
- High-performance processor secondary cache memory
- Industrial control systems operating in wide temperature environments
- Portable electronic devices requiring low-power static RAM solutions
Procurement Notes
Verify the current lifecycle status before procurement as this specific part number is listed as obsolete and end-of-life. Confirm that alternative packages or speed grades within the 71V256SA series are acceptable substitutes. Check for moisture sensitivity level requirements during handling and storage to prevent damage. Ensure compatibility with existing board layouts for the 28-SOJ footprint if replacement is necessary.
Selection Notes
Select this component when a 32K x 8 asynchronous SRAM with 15 ns access time is required for industrial temperature ranges. Consider the 28-SOJ package constraints for surface mount assembly. Evaluate power consumption limits against the 3.3V supply specifications. Compare against other speed grades like 10 ns or 12 ns variants if faster performance is needed but availability permits.
Part Context
This component belongs to the 71V256SA family of 3.3V CMOS Asynchronous SRAMs. The family offers various access times and packaging options including TSOP and SOJ types. It is designed for commercial and industrial applications requiring reliable static memory without refresh overhead. The manufacturer provides multiple suffixes indicating different temperature grades and package styles within the same core architecture.
