SST89V51 Datasheet PDF

Silicon Storage Technology SST89V51

The SST89E/V54RC, SST89E/V52RC, and SST89E/ V51RC 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 our customers.The devices use the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontroller devices. The primary partition occupies 16/8/4 KByte of internal program memory space and the secondary partition occupies 1 KByte of internal program memory space.
