Overview
The Renesas Electronics Corporation 71V256SA12YGI is a 3.3V CMOS Asynchronous Static Random Access Memory (SRAM) organized as 32K x 8, providing a total storage capacity of 256 Kbit. It features a parallel interface with a maximum access time of 12 ns. The device operates within a supply voltage range of 3 V to 3.6 V and supports an industrial temperature range from -40°C to +85°C. It is housed in a 28-pin Small Outline J-Lead (SOJ) package.
Feature Summary
- Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation
- Low standby current consumption extending battery life in portable applications
- LVTTL-compatible inputs and outputs for direct interfacing with logic systems
Applications
- High-performance processor secondary cache memory
- Battery-powered devices requiring low power standby modes
- Industrial control systems operating in extended temperature environments
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm lead-free compliance and moisture sensitivity level requirements before assembly. Check for specific RoHS exemptions if applicable to the manufacturing date code. Ensure proper handling procedures are followed during storage and installation.
Selection Notes
Select this component for designs requiring fast asynchronous access times with low power dissipation. Consider the 28-pin SOJ package constraints for PCB layout. Evaluate thermal management needs for industrial temperature ranges. Verify compatibility with existing LVTTL logic levels in the system architecture.
Part Context
This part belongs to the 71V256SA series of 3.3V SRAMs. It shares architectural similarities with other variants in the family but differs in package type and temperature grade. The SOJ packaging distinguishes it from TSOP or DIP alternatives within the same speed and organization class.
Replacement Considerations
IDT71V256SA12YGI is a verified equivalent part number representing the same component under the Integrated Device Technology brand prior to acquisition.
