●PRODUCT DESCRIPTION
●The SST89E516RDx and SST89V516RDx are members of the FlashFlex family of 8-bit microcontroller products designed and manufactured with SST’s patented and proprietary SuperFlash CMOS semiconductor process technology. The split-gate cell design and thick-oxide tunneling injector offer significant costand reliability benefits for SST’s customers. The devices use the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontrol ler devices.
