6116SA20SOG

Overview

The Renesas Electronics Corporation 6116SA20SOG is a 16Kb (2K x 8) asynchronous static random-access memory (SRAM) IC. It features a parallel interface with a maximum access time of 20 ns and a write cycle time of 20 ns. The device operates on a single 4.5V to 5.5V power supply and supports surface-mount installation in a 24-SOIC package (7.50mm width). It is designed for commercial temperature ranges from 0°C to 70°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clocks or refreshing for operation
• Reduced power standby mode capability
• TTL-compatible inputs and outputs

Applications

• General-purpose data storage in embedded systems
• Buffer memory applications
• Cache memory implementations

Procurement Notes

Verify component authenticity through authorized channels, as the part status is listed as obsolete. Confirm RoHS3 compliance and check for specific manufacturing date codes if required for legacy system maintenance. Ensure the 24-SOIC package dimensions match the target PCB footprint before procurement.

Selection Notes

Select this component when a 20 ns access speed is sufficient for the application. Consider the 6116LA series variants if battery backup data retention or lower standby current is required. Verify that the 24-SOIC package size fits the available board space and that the operating voltage range aligns with the system's power rails.

Part Context

This part belongs to the 6116SA family of 5V CMOS SRAMs. It shares architectural similarities with other members like the 6116SA15SOG and 6116SA25SOG, differing primarily in access speed specifications. The 'SA' suffix typically denotes standard performance within the asynchronous SRAM lineup.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT6116LA20SOG and IDT6116LA20SOGI.
