Features & Applications
NOTE: This SST product is migrating to the preferred Microchip (MCP) part number. All products bearing the Microchip part number are identical in form, fit and function to the products with the legacy SST prefix/logo mark.
The SST39LF400A-55-4C-EKE is a part of SST39LF series Multi-Purpose Flash. It has an standard commercial operating temperature ranging from 0°C to +70°C, it comes in a TSOP-48 package.
The SST39LF400A is a 256 K x16 CMOS Multi-Purpose Flash (MPF) manufactured with SST 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.
