6116LA20SOGI

Overview

The IDT6116LA20SOGI 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 20ns access time. 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 from -40°C to +85°C. The component includes low-power standby modes and TTL-compatible inputs and outputs.

Feature Summary

• Low-power standby mode reduces power consumption significantly during inactive periods
• Battery backup data retention capability allows operation on a 2V battery with minimal current draw
• Fully static asynchronous architecture eliminates the need for external clocks or refreshing cycles
• TTL-compatible inputs and outputs ensure straightforward integration with standard logic families

Applications

• Industrial control systems requiring reliable non-volatile-like storage without complexity
• Embedded systems needing fast, clock-free data buffering
• Battery-powered devices utilizing the low-power standby and retention features
• General-purpose memory expansion in microcontroller-based designs

Procurement Notes

Verify the specific suffix 'GI' against official Renesas documentation to confirm lead-free status and RoHS compliance details. Confirm that the 24-SOIC package dimensions match your PCB footprint requirements precisely. Check for any recent product change notices regarding assembly sites or material declarations before finalizing procurement plans.

Selection Notes

Select this component when a 20ns access speed is required alongside industrial temperature ratings. The LA variant is appropriate for designs prioritizing low standby power and battery backup functionality over higher-speed commercial variants. Ensure the system design accommodates the 4.5V to 5.5V supply voltage range and provides adequate thermal management for the SOIC-24 package.

Part Context

This part belongs to the 6116 family of 16Kb CMOS SRAMs. It shares architectural similarities with other members like the IDT6116SA series but differs in temperature rating and power characteristics. The LA designation specifically indicates the low-power version with enhanced standby capabilities compared to standard commercial grades.

Replacement Considerations

Publicly confirmed substitutes include IDT6116LA25SOGI and IDT6116SA25SOGI. These alternatives offer similar pinouts and functionality but feature a 25ns access time instead of 20ns. Verify compatibility with existing timing constraints before substitution.
