6116SA19TPG

Overview

The 6116SA19TPG is a 16Kbit asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface and is organized as 2K x 8 bits. The device operates within a supply voltage range of 4.5V to 5.5V and has a typical access time of 19 nanoseconds. It is housed in a 24-pin plastic dual in-line package (PDIP) with a 0.300-inch pitch, designed for through-hole mounting. The component supports standard TTL-compatible inputs and outputs.

Feature Summary

• Fully static asynchronous operation requiring no clock signals or refreshing cycles
• Reduced power standby mode capability for energy efficiency
• TTL-compatible input and output logic levels
• Military grade product availability within the series

Applications

• Embedded systems requiring non-volatile-like data retention during power loss via battery backup
• Industrial control systems utilizing through-hole packaging standards
• Legacy hardware maintenance and replacement scenarios

Procurement Notes

This component is officially classified as obsolete and is no longer manufactured by Renesas Electronics Corporation. Verification of authenticity is critical when sourcing from secondary markets, as counterfeit parts may exist. Buyers should confirm the specific suffix variations and check for official Product Change Notices regarding assembly facility changes or labeling updates before procurement.

Selection Notes

Select this part only if through-hole DIP packaging is strictly required by the board design. Verify that the 19ns access time meets system timing constraints. Consider the 6116LA variant if lower standby current or battery backup functionality is needed. Ensure the 5V logic compatibility aligns with the host microcontroller or processor I/O specifications.

Part Context

The 6116SA series belongs to Renesas' legacy CMOS SRAM family, originally developed by IDT. These devices are widely recognized for their reliability in industrial and military applications. The SA suffix denotes standard speed grades, while the TPG indicates the specific tape-and-reel or tube packaging configuration within the PDIP form factor.

Replacement Considerations

Official substitutes include other members of the 6116SA series with different access times or packaging options. Cross-reference with IDT6116SA equivalents. Verify pinout compatibility and electrical characteristics before substituting.
