6116LA20SOG8

Overview

The IDT6116LA20SOG8 is a 16Kb (2K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 5.5V and features a maximum access time of 20ns. The device utilizes a parallel interface and is housed in a 24-SOIC surface-mount package with a width of 7.50mm. Designed for industrial applications, it supports an operating temperature range of 0°C to 70°C. The component includes low-power standby modes and TTL-compatible inputs and outputs.

Feature Summary

• Low-power architecture with reduced standby current consumption
• Battery backup data retention capability for critical data preservation
• Fully static asynchronous operation requiring no clock signals or refreshing
• TTL-compatible input and output logic levels

Applications

• Industrial control systems requiring non-volatile-like data retention via battery backup
• Embedded memory storage for microcontroller-based designs
• Data buffering in high-speed parallel communication interfaces
• Consumer electronics utilizing standard 5V logic families

Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation, as local sources primarily list 'IDT6116LA20SO' or '6116LA20SOG'. Confirm RoHS compliance status, as some variants in this family are marked non-compliant while others meet RoHS3 standards. Check for End-of-Life (EOL) notices, as several related 6116LA parts have been discontinued. Ensure the 24-SOIC package dimensions match your PCB footprint requirements.

Selection Notes

Select this component when a 20ns access speed is required for 16Kb parallel SRAM. The LA designation indicates low-power characteristics suitable for battery-backed applications. Compare against the 6116SA series if industrial temperature ranges (-40°C to 85°C) are needed instead of commercial ranges. Verify that the 24-SOIC package fits the available board space and that the 5V logic compatibility aligns with the system's I/O standards.

Part Context

This part belongs to the IDT 6116 family of CMOS SRAMs, originally developed by Integrated Device Technology (IDT) and now produced by Renesas Electronics. The family offers various access speeds and temperature grades. The 'LA' variant specifically targets low-power applications with battery backup support. These devices are widely used in legacy and industrial systems requiring reliable, fast, static memory without refresh cycles.

Replacement Considerations

Publicly confirmed substitutes include IDT6116LA25SOG8 and IDT6116SA25SOG8. Note that these alternatives may have different access times (25ns) or temperature ranges. Verify pinout compatibility and electrical specifications before substitution.
