FlashFlex MCU
SST89E516RD2 / SST89E516RD
SST89V516RD2 / SST89V516RD
Data Sheet
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 cost and reli-
ability benefits for SST’s customers. The devices use the 8051 instruction set and
are pin-for-pin compatible with standard 8051 microcontroller devices.
