6116LA20SOG

Overview

The IDT6116LA20SOG is a 16Kb (2K x 8) asynchronous static random access memory 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. It supports an industrial operating temperature range of 0°C to 70°C. The component includes a reduced power standby mode and offers battery backup data retention capability, consuming typically 1μW to 4μW when operating off a 2V battery.

Feature Summary

• Low-power architecture with dedicated battery backup data retention capability for extended data preservation
• Fully static asynchronous circuitry operation requiring no external clocks or periodic refreshing cycles
• TTL-compatible inputs and outputs ensuring direct integration with standard logic families

Applications

• Industrial control systems requiring reliable non-volatile-like data storage during power interruptions
• Embedded applications utilizing battery-backed memory configurations for critical parameter retention
• General-purpose digital circuits employing TTL-compatible interfaces for simplified system design

Procurement Notes

Verify the specific suffix 'G' against official documentation to confirm compliance status, as historical records indicate variations between RoHS-compliant and non-compliant versions for this part family. Confirm the manufacturer's current production status, as multiple sources classify this component as obsolete or end-of-life. Ensure the required package type matches the intended PCB footprint before procurement.

Selection Notes

Select this component when a 20ns access speed is sufficient for the target application and low standby power consumption is a priority. The battery backup feature makes it suitable for designs needing data retention without complex power management circuits. Verify that the 0°C to 70°C temperature range meets the environmental requirements of the final assembly.

Part Context

This device belongs to the 6116LA series of 5V CMOS SRAMs, which are organized as 2K x 8 bits. The LA designation specifically indicates the low-power variant equipped with battery backup functionality. This series represents a standard solution for parallel memory interfaces in legacy and industrial electronic designs.

Replacement Considerations

Publicly confirmed substitute part numbers include 6116LA25SOG8 and 6116SA20SOG8.
