6116SA15TPGI

Overview

The Renesas Electronics Corporation 6116SA15TPGI is a 16-kbit asynchronous static random-access memory (SRAM) organized as 2048 words by 8 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The device utilizes a parallel interface and is housed in a 24-pin plastic dual in-line package (PDIP). It supports through-hole mounting and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clocks or refreshing for operation
• Reduced power standby mode with battery backup data retention capability
• TTL-compatible inputs and outputs for direct logic interfacing

Applications

• High-speed buffer memory in embedded systems
• Secondary cache storage for microprocessors
• Data logging applications requiring non-volatile-like retention via battery backup

Procurement Notes

Verify component authenticity and datasheet alignment, as the 6116SA15TPG series has reached end-of-life status. Confirm that the specific suffix corresponds to the PDIP-24 package variant. Check for RoHS compliance documentation and ensure availability from authorized distributors or surplus suppliers due to discontinuation.

Selection Notes

Select this component when a 15 ns access speed and 2Kx8 organization are required for asynchronous SRAM applications. Ensure the design accommodates the 4.5V to 5.5V supply voltage range and the 24-pin DIP footprint. Consider the low-power standby feature if battery-backed retention is necessary for the target application environment.

Part Context

This part belongs to the 6116 family of 5V CMOS SRAMs manufactured by Renesas Electronics. The family offers various access times and packaging options, including SOIC and TSOP variants. The 6116SA15TPGI specifically denotes the 15 ns speed grade in a through-hole DIP package, serving legacy designs requiring robust, clockless memory solutions.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT6116SA15TPG. Verify pinout compatibility and electrical specifications before substitution.
