Product Summary

The 29SF040 is a CMOS Small-Sector Flash (SSF) manufactured with SST’s proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. The 29SF040 is suited for applications that require convenient and economical updating of program, configuration, or data memory.
