PRODUCT DESCRIPTION

SST89E564RD, SST89V564RD, SST89E554RC, and SST89V554RC are members of the FlashFlex51 family of 8-bit microcontrollers. The FlashFlex51 is a family of microcontroller products designed and manufactured on the state-ofthe-art SuperFlash CMOS semiconductor process technology. The device uses the same powerful instruction set and is pin-for-pin compatible with standard 8xC5x microcontroller devices.
