6116LA19TPG

Overview

The Renesas 6116LA19TPG is a 16Kbit asynchronous static random-access memory (SRAM) organized as 2K x 8. It features a parallel interface with a maximum access time of 19 nanoseconds. The device operates on a single 5.0V supply voltage and supports an industrial temperature range from -40°C to +85°C. It is housed in a 24-pin Thin Small Outline Package (TSOP). Key electrical characteristics include a write cycle time of 19ns and TTL-compatible inputs and outputs, ensuring compatibility with standard logic families.

Feature Summary

• Low-power standby mode for reduced energy consumption
• Battery backup data retention capability with micro-watt current draw
• Fully static asynchronous operation requiring no clocks or refreshing
• TTL-compatible inputs and outputs for broad system integration

Applications

• Industrial control systems requiring non-volatile-like data retention via battery backup
• Embedded applications needing fast, clock-free memory access
• Military grade electronic equipment operating in extreme temperatures
• Portable devices utilizing low-power standby modes

Procurement Notes

Verify the specific suffix 'TPG' corresponds to the TSOP-24 package and industrial temperature range (-40°C to +85°C). Confirm RoHS3 compliance status for environmental regulations. Ensure the source document explicitly lists this part number as active or obsolete to determine availability. Cross-reference pinouts with official datasheets to prevent integration errors during PCB design.

Selection Notes

Select this component when a 16Kbit capacity with 19ns speed is required in a TSOP-24 form factor. It is suitable for designs needing battery-backed SRAM functionality without complex refresh cycles. Compare against the 6116LA25 variant if slower speeds are acceptable for cost reduction. Ensure the system voltage aligns with the 5V requirement and that TTL input compatibility meets interface standards.

Part Context

This part belongs to the 6116 family of 5V CMOS SRAMs from Renesas. The 'LA' designation indicates the low-power version with battery backup support. The '19' denotes the 19ns access speed class. The 'TPG' suffix specifies the TSOP-24 plastic package and industrial temperature rating. This family is designed for general-purpose memory applications where power efficiency and data retention are critical.

Replacement Considerations

The 6116LA25TPG is a similar alternative with a 25ns access time. Verify package compatibility and speed requirements before substitution. Check for any differences in standby current specifications between variants.
