6116SA35SOG

Overview

The IDT6116SA35SOG is a 16K-bit (2K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates within a voltage range of 4.5V to 5.5V and features a maximum access time of 35 ns. The device utilizes a parallel interface and is housed in a 24-SOIC surface-mount package with a width of 7.50 mm. Designed for industrial applications, it supports an operating temperature range from -40°C to +85°C. The component is classified as volatile memory technology.

Feature Summary

• Asynchronous operation requiring no external clock signals or periodic refreshing cycles
• Reduced power standby mode for energy conservation
• TTL-compatible inputs and outputs for direct logic interfacing

Applications

• Industrial control systems
• Data acquisition modules
• Embedded storage buffers

Procurement Notes

Verify RoHS compliance status carefully, as the specific suffix variant may not meet current environmental directives. Confirm end-of-life status through official Renesas channels before finalizing design-in decisions. Ensure supply chain stability due to potential discontinuation risks associated with legacy SRAM families.

Selection Notes

Select this component when a 35 ns access speed is sufficient for the target application. Compare against faster variants like the 25 ns version if higher throughput is required. Verify that the 24-SOIC footprint aligns with existing PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the IDT6116 family of CMOS SRAMs. The 'SA' suffix typically denotes standard asynchronous performance, while '35' indicates the access speed class. The 'SOG' suffix specifies the SOIC-24 plastic package configuration. This series provides a cost-effective solution for low-density memory needs in embedded environments.

Replacement Considerations

Direct substitutes include other 16Kb asynchronous SRAMs with identical pinouts and electrical characteristics. Check for updated lead-free versions within the same manufacturer's portfolio to ensure regulatory compliance.
