PRODUCT DESCRIPTION

The SST89E5xRD2/RD and SST89V5xRD2/RD are members of the FlashFlex51 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 reliability benefits for SST¡¯s customers. The devices use the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontroller devices.
