FlashFlex MCU
SST89C58RC
SST89C58RC is a member of the FlashFlex family of 8-bit microcontrollers
designed and manufactured with patented and proprietary SuperFlash CMOS
semiconductor process technology. The split-gate cell design and thick-oxide tun-
neling injector offer significant cost and reliability benefits for customers. It uses
the 8051 instruction set and is pin-for-pin compatible with standard 8051 micro-
controller devices.
