PRODUCT DESCRIPTION

SST89E564, SST89V564, SST89E554, and SST89V554 are members of the FlashFlex51 family of 8-bit microcontrollers. The FlashFlex51 is a family of microcontroller products designed and manufactured on the state-of-the-art SuperFlash CMOS semiconductor process technology. The device uses the same powerful instruction set and is pin-forpin compatible with standard 8xC5x microcontroller devices.
