SST (Silicon Storage Technology) is now a wholly owned subsidiary of Microchip Technology, which acquired SST in April 2010. SST bases its FlashFlex family of 8-bit microcontroller products on the company's SuperFlash CMOS-semiconductor-process technology. These microcontrollers implement the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontroller devices. FlashFlex microcontrollers are available in single- or dual-block configurations, and they are ISP (in-system-programmable) and IAP (in-application-programmable). These microcontrollers target consumer, communication/wired, imaging and video, audio, industrial, and motor-control applications.
