6116SA25TPG

Overview

The Renesas Electronics Corporation 6116SA25TPG is a 16 Kbit Asynchronous Static Random Access Memory (SRAM) organized as 2K x 8. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 25 ns. The device utilizes a parallel interface and is housed in a 24-PDIP through-hole package. It supports standard single data rate (SDR) operations with fully static asynchronous circuitry, requiring no clocks or refreshing for operation.

Feature Summary

• Fully static asynchronous architecture eliminates the need for external clock signals or periodic refresh cycles during operation.
• Integrated reduced power standby mode significantly lowers energy consumption when the device is not actively accessed.
• TTL-compatible inputs and outputs ensure straightforward integration with standard logic families without additional level shifting.

Applications

• Secondary cache memory for microprocessor systems
• Buffer storage in industrial control applications
• Data logging and temporary storage in embedded devices

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details via official datasheets. Check for alternate assembly facilities listed in Product Change Notices. Validate package dimensions against ECAD models before PCB layout finalization.

Selection Notes

Select this component for designs requiring low-power static RAM with TTL compatibility. Ensure operating temperature ranges match environmental conditions. Verify that the 25 ns access time meets system timing requirements. Consider the 24-PDIP package constraints for mechanical integration.

Part Context

This part belongs to the 6116 series of 5V CMOS SRAMs. It shares architectural similarities with other variants in the family but differs in speed grade and packaging. The SA suffix typically denotes specific speed and package combinations within the Renesas memory portfolio.

Replacement Considerations

IDT6116SA25TPGI is a documented alias for this component. Verify pinout and electrical specifications against original datasheets before substitution. Cross-reference with current Renesas product availability lists for active alternatives.
